SITE DESCRIPTION
Current / Proposed State, Topography & Drainage
The proposed development is located on the eastern side of Hoey Street.
It currently houses 15 units, 1 community building and 1 utility shed.
The development proposes to remove 8 of these units and the utility shed and replace with 12
units giving a total of 19 units.
The site is extremely flat with low point pockets around the site with elevations around RL
16.50m.
In its current state it is hard to determine if there is an upstream catchment entering the site, it is
assumed that in a flood event the flood waters would be a sheet flow around the site.
The site currently has an internal drainage system that appears to discharge all rainwater off
site in a controlled manner.
It is intended to abandon this existing system and direct all future site runoff including the roof,
pavement and landscaping to the existing 1200 dia pipe in Hoey Street.
As such this is deemed to be the legal point of discharge.

Soils
A Geotechnical investigation has not been undertaken for this site to date. For the purposes of
this report only it is assumed that the soils in this region are silty clay.
Watercourses
There are no defined watercourses from upstream catchments running through the site, the
upstream catchment if not restricted will sheet flow through the site.
Flooding Issues
The site is in close proximity of Plane Creek and although the Mimaps system does not indicate
it is in a flood zone it must be categorised as high risk. Checks should be undertaken with
Council to confirm the status of the site and any floor levels be set 300mm above any flood level
Data
Existing Stormwater Infrastructure
A review of the site survey information indicates there is an existing 1200 dia pipe in Hoey
Street.
It is intended that the proposed drainage system discharges to this system.
Related Studies
No studies are known to have been undertaken on the surrounding catchment.
Stormwater Management Plans
The Site Based Stormwater Management Plan (SBSMP) described below is in accordance with;
• The Queensland State Planning Policy – July 2014
• Mackay Regional Council – MUSIC Modelling Guidelines
• The Queensland Urban Drainage Manual and the
• EPA Best Practice Urban Stormwater Management – Erosion & Sediment Control
Guidelines.
Hydrologic & Hydraulic needs/wants
As the site is extremely flat it is difficult to anticipate where the runoff will discharge from the
site. As such it is recommended that the site have various low points with inlet pits in locations
similar to those shown on the plans attached to this document. The locations of these are to be
confirmed during the civil works design stage.
Water Quality/Stream Health
No study has been undertaken to determine the water quality of the recipient waterway and
does not form a part of this document.

OPPORTUNITIES AND CONSTRAINTS
Key Site Characteristics
The current capacity of the existing 1200 dia pipe is unknown, an analysis to check its current
capacity and a comparison with the possibility of the upstream catchment being fully developed
has been undertaken and is discussed further in this document.
There are no major constraints for the proposed development that cannot be dealt with using
conventional engineering design practices.
Previous Studies / Plans
There are no known previous studies undertaken for this site.

STORMWATER QUANTITY
Methodology
To undertake the hydrologic analysis of the development, the Queensland Urban Drainage
Manual (QUDM) has been used. Flows and levels have been calculated using a rainfall intensity chart developed using the Bureau of Meteorology IFD software (refer Appendix A) for the
Serina area.
Watercom Drains
A hydrologic assessment of the proposed system has been undertaken using Watercom Drains,
producing an Ilsax model to assess the runoff.
The model has been set up with two systems, the first being the pre-developed, unmitigated,
site, the second is the developed site.
The developed scenario will require onsite detention to mitigate the increase in flows, it is
proposed to use the bio-retention system (discussed further in this report) as the detention basin with the storage volume for detention being stored above the extended detention level for
treatment.
Therefore the detention volume has been calculated ignoring the possible volume between the
top of the filter level and the top of the outlet pit.
Assessment
Two assessments have been undertaken the first is an onsite analysis of stormwater runoff, the
second is an analysis of the existing 1200 dia pipe.
1. Analysis of Site Runoff
From the supplied survey information a hydraulic analysis comparing the existing &
proposed final development has been undertaken.
This was undertaken using Watercom drains with the following parameters being
adopted.
It should be noted that only the area of development has been assessed the two units
on the southern leg of the site have been excluded from all calculations.

Using these parameters the modelling produces a runoff for the pre-developed site of
0.398m3/s & 0.713m3/s for the 20% & 1% AEP events respectively.
The developed site produces 0.424m3/s 0.760m3/s for the same storm events.
This results in an increase 0.026m3/s (6.5% increase) and 0.047m3/s (6.6% increase)
when compared to the existing scenario.
Full calculations can be found in Appendix B
2. Existing 1200 diameter pipe capacity check.
From a desktop study of a Google Earth image and its associated surface contours,
Mimaps contours and discussions with Council it is determined that a contributing upstream catchment of around 1.0Ha can be attributed to the 1200 diameter pipe.
Using Bransby Williams formula we ascertain that the time of concentration for this
catchment is 28 minutes. For the purposes of calculation 30 minutes has been adopted.
Refer Appendix C
This pipe has then been modelled in Watercom Drains to determine the HGL levels for
the current catchment and a possible fully developed upstream catchment.
The following parameters were adopted;
Parameter Existing (Fi 0.10) Possibly Developed (Fi 0.70)
Site Area (ha) 28.197 28.197
Impervious 10 70
Pervious 90 30
Time of Concentration (mins) 30 30
It should be noted that the pipe details have been adopted as best as possible from Council
supplied as constructed information no pit losses were adopted due to lack of information, pipe
has been modelled as one continuous length.
The resulting calculations indicate a headwater level of 16.37 for the Fi 0.10 option and 16.58
for the Fi 0.70 option.
The surface level at this point is 16.81 therefore there is satisfactory headwater freeboard to
suggest that the existing 1200 dia pipe has sufficient capacity to convey the increased flow from
the proposed development.
Please note that the Google earth surface levels have not been confirmed and may be
inaccurate but are deemed sufficient to assess an approximate contributing catchment for the
purposes of overland flow assessment.
Full calculations can be found in Appendix C

Proposed mitigation measures
The following is proposed as a best practice site specific solution.
Various aspects of this development has been considered when assessing any mitigation
measures including the existing 1200 dia pipe, the increase in runoff for the developed site and
the proximity of the site to Plane Creek with the following deductions made;
1. The increase in runoff due to the development is only 27l/s or 6% more than the existing
site for the 20% AEP event.
2. The 1200 diameter pipe has sufficient capacity to include this additional runoff.
3. The site is in close proximity to Plane Creek, a continuously flowing waterway, being
only 30m from this waterway.
Due to the above considerations it is deemed unlikely that the increase in runoff from the site will impact on any neighbouring properties or the existing drainage system.
As such no mitigation to the increase in runoff is proposed.

Stormwater Quality
Existing Conditions
As previously stated the site is an existing unit development that was undertaken some years
ago and has no stormwater quality devices or management plans in place.
Receiving Waters
The receiving water for this development has been identified as Plane Creek which is
approximately 30m to the south of the site.
The proposed works for the site are not considered substantial enough to impact greatly on this
system and is discussed further in this document.
The main concern for pollutants entering the water body is the possibility of sediment entering
the stormwater system during the construction phase. The mitigation measures for the
construction phase are detailed in the following section.
Identification of Environmental Values & Water Quality
Being a development that is in close to the receiving waterway it is highly likely that this
development could have some impact on the receiving waters.
Objectives
The State Planning Policy July 2014 Part E defines the criteria used to determine a whether the
policy applies to a material change of use development as being the following; i. Greater than 2500m2 and will either;
a. result in an impervious area greater than 25% or
b. result in 6 or more additional dwellings.
The site exceeds all of these trigger points and as such stormwater management is referable to
the Queensland Department of State Development, Infrastructure & Planning (DSDIP).
This development does not trigger any requirements for Waster Water Management or Non-
Tidal Artificial Waterways so only the sections of the State planning policy that relate to
Stormwater Quality have been addressed and has been assessed in accordance with Part D –
Environment & Heritage – Water Quality and Part H – Appendix 2.
A MUSIC model prepared in accordance with the Mackay Regional Council – MUSIC Modelling
Guidelines and will be used to determine the level of treatment for this development.

During the construction phase the pollutants typically generated are;
Pollutant Sources
Litter Paper, construction packaging, food packaging, cement bags,
offcuts
Sediment Unprotected exposed soils and stockpiles during earthworks & building
Hydrocarbons Fuel & Oil spills, leaks from construction equipment
Toxic Materials Cement slurry, solvents, wash waters (e.g. from tile works)
pH altering substances Acid sulphate soils, cement slurry and washwaters
During the operational phase the pollutants typically generated for townhouse developments
are;
Pollutant
Litter Pathogens Surfactants
Sediment Faecal coliforms Thermal Pollution
Nitrogen Hydrocarbons
Phosphate Heavy Metals
This section details the treatment to be used for the construction phase of the development.
Acid Sulphate Soils
Councils Mimaps system indicates that the site is not in a potential acid sulphate soil area.
Construction Phase Potential Sediment Generation
The development will result in one catchment from which sediment can be generated. The area
to be disturbed is 0.6200ha which is the areas of pavement and building works only, the
remainder of the site is not anticipated to be disturbed. While the potential exists for sediment
to be generated during the construction phase, the potential sediment volume is dependent
upon rainfall, site topography, the material type exposed, flow characteristics, and the
construction practices and programme.
The potential for sediment generation for the site in the pre-development stage and due to the
development is calculated using the Revised Universal Soil Loss Equation. The sediment generation potential for the pre-development stage is calculated at 1.11m
3/year. Detailed
calculations are contained in Appendix D.
The potential sediment yield during construction will vary with the extent of site exposed during
the construction programme. The potential for impact will be staged as follows:
• After clearing, the site of works will be subject to the erosion impacts (total area
0.6200ha).
• The estimated time for reshaping ground for building platforms and roadways will take some 28 days. After this time the site, will progress directly to the construction phase.
• It is estimated the time from the completion of the reshaping to the completion of the
building pads will be 120 days. After this time the site contribution to potential sediment
generation, will be reduced.
• It is estimated the time from the completion of the reshaping to the completion of the driveway and other hardstand areas will be approximately 28 days.

STRUCTURAL AND CIVIL ENGINEERING FOR RESIDENTIAL, COMMERCIAL AND INFRASTRUCTURE PROJECTS
Based on this program the estimated potential yield of sediment during construction is
calculated at 3.54m3.
The possible sediment generated is not considerable and the use of a sedimentation fence is
deemed satisfactory.
Upon completion of the proposed development the potential sediment yield is 0.33m3/year.
This is considerably less than the pre-development stage yield and is due to the increase in
non-erodible surface area.
The external environment will benefit greatly as a result of the decrease in sediment load.
Construction Phase Control Measures
The works proposed to control erosion are:
• Construct stabilised shake down area at the site access.
• Erect sediment fences as detailed on the civil works drawings.
• Strip topsoil and stockpile within the controlled area on site. Remove from the site any material which is not required for rehabilitation of disturbed areas.
• Exposed soils and stockpiles are to be watered, as required, to minimise soil losses as
a result of wind.
• Ensure all litter is collected and disposed of onsite in an appropriate fashion.
• Ensure all machinery is in good working order, repair any leaks immediately.
• Contain any spills immediately to ensure that they do not enter the stormwater system.
• All wash waters are to be kept away from the stormwater system.
• Finalised earthworks to be top soiled and seeded/hydro-mulched or landscaped as directed
• Place geo-textile field gully inlet filters around entry points to the drainage system until
the pavement is complete or until grass is established.
• Construct buildings and hardstand areas.
• Geo-textile filters to be replaced with mesh filters until landscaping is complete and stabilised.
• Maintain all sediment devices and other interim controls regularly
• Remove sediment fences and inlet filters after the establishment of the landscaping and
grass cover.
Refer to drawing 2758-SK1 & SK2 for location and details
Erosion and Sediment Control Management
The installation of erosion and sediment control devices requires maintenance of these devices
to ensure their effectiveness in the control of potential environmental impact. Summary of the objectives and maintenance requirements for this project are detailed below.
Objectives
The objectives of this erosion and sediment control plan are:
To ensure that the water quality of the receiving waters is not worsened by the site’s
development minimise sediment transport in surface water runoff during the construction and
operational stages.
And to provide a monitoring and maintenance programme for implementation during the construction phase.

STRUCTURAL AND CIVIL ENGINEERING FOR RESIDENTIAL, COMMERCIAL AND INFRASTRUCTURE PROJECTS
Maintenance of Controls
The Contractor is responsible for the installation and maintenance of the sediment and erosion
control measures during the construction phase and the defects liability period (normally six
months).
Maintenance responsibilities for the establishment of vegetation, which is the requirement to
irrigate the plants and grass used to generate ground cover, lies with the Contractor initially but
ultimately reverts to the property owners once the defects liability period has expired.
Maintenance will require:
• Inspection of silt fences, diversion drains and hay bale barriers weekly during construction and after any rainfall event.
• Inspection of temporary sediment ponds weekly during construction and after any
rainfall event
• Clean out sediment build-up following each event that causes deposits.
• Clean up soil and sediment deposits promptly as they occur.
• Provide inlet protection where soil disturbance is to occur.
Responses to Complaints
Complaints during this type of construction usually relate to noise and dust. Generally the complaint is made known to the Contractor, the Principal, the Superintendent and/or the
Council.
The Contractor shall keep a record of all complaints identifying the nature of the complaint and
any remedial action taken to address such complaint. The Contractor shall act as soon as
possible to remedy the problem, if the complaint is considered valid and reasonable. A
complaints record shall be made available by the contractor for regular inspection by the
Superintendent. For the purpose of direction by others, the Contractor’s details are to be
supplied to Council prior to commencement of the works.
Complaints relating to dust shall require the Contractor to immediately water the exposed earth
surfaces and any soil stockpile areas as well as haul roads to control dust. Such watering shall occur immediately the complaint is registered with the Contractor. Watering should continue
periodically until conditions suit, or the works are completed to a state that prevents dust
transport.
Monitoring
The installation of the erosion and sediment control measures as detailed in this plan will
ameliorate potential impact to water quality in the receiving waters. A monitoring program is
proposed to ensure that the control measures achieve the desired goals.
A visual monitoring program is proposed due to the relatively small size of the development and
the amount of earthworks is to take place.

Operational Phase
The operational phase of the development will require any mitigation of the stormwater quality in accordance with the State Planning Policy – July 2014.
As this development triggers referral to the DSDIP and as such site based stormwater quality
treatment must be implemented to achieve the objectives of the State Planning Policy.
Therefore a MUSIC Model has been developed in accordance with the Mackay Regional
Council – MUSIC Modelling Guidelines to determine the best practice technique to be adopted
for this development.
Existing Conditions The site is currently one catchment with a formal drainage system that will be removed and
replaced with a new system, the existing system does not have any treatment devices installed.
This catchment has been defined by contours supplied by field survey.
Receiving Waters The existing condition of the receiving waterway is unknown so it is intended to keep the post
development runoff levels to those required by the State Planning Policy – July 2014. The
objectives of which are detailed below.
The receiving waterway may be impacted upon due to an increase of nutrient pollutants as a
result of this development. Any increase in litter, nutrients or suspended solids entering this
body of water can impact on the ecosystem therefore all runoff will be treated to ensure a
beneficial effect on water quality.
Objectives
The use of stormwater quality improvement devices (SQUIDs) will address the State Planning
Policy objectives for South East Queensland as detailed below.
80% reduction in total Suspended Sediment (TSS)
60% reduction in total Nitrogen
45% reduction in total Phosphorous
90% reduction in total Gross Pollutants
These have been adopted from Appendix 2, Table B of the above document and are in relation
to the developed untreated site.
Methodology The pollutant impact assessment has been carried out using the MUSIC model system. The
pollutant assessment considered two scenarios as follows:
Post Development untreated.
Post Development treated.
The post development model has numerous catchments which have divided into separate
categories that represent roof, hardstand & landscaping.
The catchment land use for each of the post-development nodes has been set up in accordance

with Section 4.2 of the MUSIC guidelines for Urban Residential Use.
The pluviograph data used in the modelling was the Serina Post Office Station Number 033067. A ten year, six minute time step rainfall data was used from 01 January 1990 to 31 December
1999 to run the MUSIC model.
The daily values for average areal potential evapotranspiration for the site were inputted based
on Section 4.1 Table 3 of the Music Modelling Guidelines.
The proposed treatment train for the sub-catchments is as follows:
• Stormwater from the roofs of the proposed units are to be captured by a minimum 3KL rainwater tank, as the units are small (150m2) the entire roof is to be captured.
• Stormwater from the ground, both pervious & impervious areas, such as garden, grass,
landscaping, footpaths and accessway is to drain to the internal drainage system within
the site.
• All pits are to have an Enviropod 200 installed.
• This system is to discharge to a proposed filter chamber that incorporates 6x storm 360 ZPG filters (460mm high) or similar approved product.
• This chamber is to discharge to the existing 1200 dia pipe in Hoey Street..
The treatment train nodes and catchments have been set up in accordance with the MUSIC
Modelling Guidelines.
The post developed scenarios are tabulated below.
It should be noted that the drainage links were modelled with no routing as each catchment had
a similar time of concentration.
Model Analysis The modelling resulted in the following:

A review of the MUSIC model results shows that the proposed stormwater treatment train
through the use of the Storm 360 Enviropod filters and the filter system system will reduce the
expectant pollutant export loads leaving the site. The comparison of results between Post
Development (untreated) and Post Development (treated) models shows that the inclusion of
the proposed stormwater treatment train will reduce the TSS loads by 88%, the TP loads by
60% and the TN loads by 61%.

Impact of Development
The development of this site will increase loadings on the stormwater quality which is to be
minimised by the implementation of primary and secondary treatment devices as detailed in this report and will be monitored and reported as detailed in Appendix F.
Proposed Management Strategies
The objective is to provide a stormwater drainage system that reduces the impact of the
development compared with the existing pre-development loads. Management practices to
assist in the reduction of the reliance on the primary treatment structures will be implemented.
Provision of long term water quality monitoring for this development is considered impractical.
Hence, the operational monitoring will consist of 1 to 2 event samplings per year collecting
stormwater prior to it leaving the site if requested by Council. Monitoring shall be for the
following:

STORMWATER MANAGEMENT OPTIONS
Selection & Assessment of Stormwater Quality Controls.
Two forms of treatment are proposed to address the stormwater quality within the site.
Storm 360 Enviropod 200 baskets are to be used as primary treatment devices for water from
the site catchment, these devices are to be installed in all pits.
Secondary treatment will be in the form of a bio-retention system.
These are to be installed and maintained in accordance with the manufacturers’ specification for the proprietary devices shown in Appendix F.
Integration with Waterway Corridor
The catchment will drain into the public drainage system that connects to the receiving
waterway.

Maintaining the EnviroPod® Stormwater Gully Pit Insert
Maintenance is as integral to every stormwater management system as it is to any other item of machinery or equipment.
The primary purpose of the EnviroPod® Stormwater Gully Pit insert is to filter out and remove pollutants from entering our waterways. To ensure that the EnviroPod® continues to function effectively, it is important that the pollutants it captures are periodically removed, and the filtration components properly cleaned.
Maintenance requirements and frequency are dependent on the pollutant load characteristics of each site, as well as the occurrence of events such as chemical spills or excessive sediment loading due to site erosion or extreme storms. Similarly, the system should be inspected after all major storm events.
2 Stormwater360 Operations and maintenance

Treatment Train Specifications
Stormwater360 Operations and maintenance 3
The components of any proposed the treatment train or technology, including a gully pit basket upstream of a radial flow cartridge filtration system, must be evaluated for a range of pollutants and these performance expectations must comply with current best practice guidelines, i.e. Water by Design "MUSIC Modeling Guidelines version 1.0 2010" for South East Queensland.
In short, the performance evaluation of any system must show:
1 Any reduction efficiencies are justified by rigorous scientific testing as determined by an independent peer reviewer and the results further peer reviewed and published in a credible scientific journal. Any potential or perceived conflicts of interest should be disclosed within the published article.
2 Published article providing insight into the pollutant composition (e.g. soluble vs particulate for nitrogen) and the mean concentration of inflow and outflow to compare to local and or regional conditions.
3 Performance evaluation undertaken in dry weather conditions or a method to take into account any potential leaching of nutrients that may occur in the system(s).
4 Evaluation is conducted using full-scale systems with details of treatable flow rates sampled and how they correlate to discrete removal efficiencies and comparisons to the designed treatable flow rates of the device. A comparison should also be made to the climatic conditions especially where un-restricted filters are used.
Maintenance Overview
The primary purpose of the Stormwater Treatment Train is to filter out and prevent pollutants from entering our waterways. Like any effective filtration system, periodically these pollutants must be removed to restore the system to its full efficiency and effectiveness.
Maintenance requirements and frequency are dependent on the pollutant load characteristics of each site. Maintenance must be performed in accordance with the Treatment Trains Operation and Maintenance Guidelines.

This manual has been designed to assist you with cleaning and maintaining the EnviroPod Stormwater Gully Pit Insert, using the methods recommended by the manufacturer.
The cleaning process and methods described cover all aspects of the system, including:
• Removing the grate
• Cleaning the filter bag
• Inspecting the unit
• Rejuvenating the filter bag
• Re-installing the filter bags.
The manual should be used in conjunction with your site’s traffic management and safety plans, as well as other appropriate Stormwater360 (IES) documents such as the IES Employee Health and Safety Manual. We also recommend that maintenance and cleaning contractors, or device owners, develop their own site-specific health and safety activity plans to ensure a safe work environment.
Please note: This manual consists primarily of the processes and tasks associated with the hand maintenance and inductor maintenance procedures. It does not include details of the site’s traffic management or occupational health and safety requirements. Contractors or IES staff should utilise their own Employee Health and Safety Manual, which details the policies and procedures for safe work.
Why cleaning and maintenance are so vitally important
Adhering to the inspection and maintenance schedule of each stormwater treatment device is essential to ensuring that it works properly throughout its estimated design life.
During each inspection and clean, details of the mass, volume and type of material that has been collected by the device should be recorded. This data will assist with the revision of future management plans and help determine maintenance interval frequency. It’s also essential that qualified and experienced personnel carry out all maintenance (including inspections, recording and reporting) in a systematic manner. To ensure consistency, we recommend that one person be responsible for overseeing the management of the maintenance and cleaning process.
Maintenance of your stormwater management system is essential to ensuring ongoing at-source control of stormwater pollution. Maintenance also helps prevent structural failures (e.g. prevents blocked outlets) and aesthetic failures (e.g. debris build up).
Introduction
Stormwater360 Operations and maintenance 5
The EnviroPod has been designed to trap and retain pollutants in stormwater runoff, helping to maintain the quality of water entering our aquatic ecosystems. Depending on the nature of your site, pollutants can range from organic material such as leaves and sticks through to debris such as broken glass, syringes or other potentially harmful materials.
Access to gully pits containing EnviroPods may require removing heavy protective grates, while cleaning such pits may entail working in confined spaces. For these reasons, all aspects of maintaining and cleaning your EnviroPod require careful adherence to Occupational Health and Safety (OH&S) guidelines. Doing so will ensure that all maintenance personnel are adequately protected and have been properly trained before taking part in any specialist activities. The same level of care needs to be taken to protect non-work personnel in and around the site, while appropriate traffic control measures must be put in place where collection pits are situated in, or adjacent to, roadways or car parks.
The procedures indicated in the Operations section of this manual are recommended as the safest and most efficient manner of conducting the maintenance of EnviroPod units (Section 2), however contractors and cleaning staff may vary the procedure in response to the site conditions; varying work practices; or general preferences in the cleaning techniques. Please note that procedures outlined in this manual are not exhaustive, and that any changes made should always comply with general safe work practices.
Cleaning of EnviroPod filters and StormFilters is a specialist activity. The material collected by the devices can be harmful, and needs to be handled correctly. For example, sediments may contain heavy metals and carcinogenic substances as well as harmful objects such as broken glass and syringes. It is essential that Occupational Safety and Health guidelines are followed at all times, and that the following steps are carried out to ensure safe and successful maintenance operations.
In addition to the dangers associated with the cleaning and handling of material in the filter bags, precaution needs to be taken with activities such as removing the grate as well as with managing the traffic, pedestrians and other non-worker personnel at the site. The general workplace hazards associated with working outdoors also need to be taken into account..
Health and safety
6 Stormwater360 Operations and maintenance
2.1 Personnel health and safety
All contractors and staff must comply with all current workplace health and safety legislation and take all practicable steps to:
• Comply with all applicable laws, regulations and standards
• Ensure that all employees, contractors and visitors are informed of and understand their obligations in respect of current workplace health and safety legislation
• Ensure that employees understand and accept their responsibility to practice and promote a safe and healthy work environment.
Take proper care. Pollutants can range from organic materials such as leaves and sticks through to debris such as broken glass, syringes or other potentially harmful materials.
While cleaning and maintaining filters, all relevant precautions must be taken to prevent contact with sediment and litter. This includes wearing the following personal protective and safety equipment:
• Puncture resistant gloves
• Steel capped safety boots
• Fluorescent safety vest
• Overalls or similar skin protection
• Safety apron (if necessary)*
• Eye protection (if necessary)*.
* Higher personal safety conditions may be required when maintaining units that may contain more hazardous material, for example pits where syringes have been observed or pits located in areas associated with such activities.
Stormwater360 Operations and maintenance 7
2.2 Traffic control
Stormwater collection pits are typically situated either in or on roads and car parks, or adjacent to roads in a footpath or swale. Traffic control requirements across all such locations differ with most of the state and local road authorities requiring the same controls to be implemented whether the work is to be conducted on the road or on the road reserve.
As traffic requirements differ depending on road usage and the specific road configuration, separate traffic control plans should be prepared for each site. Given that maintenance is typically a quick process, the contractor should liaise with the relevant road authority to determine the specific road safety requirements for each location to ensure that on site workers can conduct the cleaning operations safely and efficiently, while complying with all laws and regulations.
State government publications such as the NSW RMS Traffic Control at Work Sites safety manual outline the signage requirements, placement of barricades or witches hats and the positioning of traffic control personnel that’s required when working on public roads. For increased safety, IES recommends that the maintenance vehicle be used to shield the work area from oncoming traffic.
Photo 1 shows the maintenance vehicle with cones placed around and positioned to shield the work area. Photo 2 shows the head-on view, note the vehicle is positioned to allow access to the drive, whilst still blocking the pit from on-coming traffic. The vehicle has a flashing light on the roof and the hazard lights switched on.
Photo 1 Vehicle positioned near pit, preventing traffic from passing close to the pit.
2.3 Confined spaces
Confined space entry procedures are not included as part of this manual. For IES employees these procedures are included as part of the IES Safety Manual. It is recommended that all contractors evaluate their own needs for confined space entry and compliance with Occupational Health and Safety regulations.
When repairs or maintenance activities cannot be conducted from the surface, and there is a need to enter and work in a confined space, only staff with current confined space training are permitted to operate in a confined space. Appropriate measures and controls must be put in place to meet confined space entry requirements. At all times the necessary safety equipment must be worn, and where gas or oxygen hazards occur, only staff trained in its use will use breathing apparatus gear. Non-trained staff must not go into confined spaces.
Confined spaces pose a serious safety hazard for all personnel; however during the normal maintenance procedures there should be no reason to enter a confined space and all maintenance procedures are able to be conducted from the surface.
Photo 2 Head-on view, indicating the placement of the vehicle near the pit.
8 Stormwater360 Operations and maintenance
EnviroPod units need to be regularly inspected to determine whether they require maintenance or cleaning. This process involves several steps, and may require two or more maintenance personnel working together, as well the use of specialised equipment such as a hydraulic lifting arm or an inductor truck with a vacuum hose.
As gully pit grates are usually quite heavy, it is important that correct lifting procedures are adopted, and that the area surrounding the opened pit is shielded from access to non-work personnel.
If inspection reveals that the filter bag needs to be emptied and rejuvenated, the entire unit should also be examined to ensure that all connections and joints are sound. Any material that has accumulated in the overflow diversion channels or outlet pipes also needs to be removed, with those areas then being flushed. Where required, filter bags may need to be cleaned or repaired, and all waste material must be disposed of according to local guidelines at either an approved disposal site or transfer station.
This section outlines the procedures for cleaning the EnviroPod units. It has been written so that someone who has never previously encountered a stormwater pit or an EnviroPod unit can carry out such maintenance by simply following the outlined steps.
3.1 Maintenance and monitoring of EnviroPod filters
To ensure that each EnviroPod unit achieves optimal performance, the material collected by the filter bag should be emptied when the level of material is no more than approximately half to two thirds of the total bag depth or when there is evidence of material overflow. While the bag has a greater storage capacity, it is recommended that it is not left to fill completely prior to emptying, for the following reasons:
• the bags are capable of retaining a heavy mass of material (in excess of 50kg), which will make them more difficult to lift and empty
• material near the top of the bag can be re-suspended during high to extreme rainfall events
• blockage of the overflow sections can occur, when material is allowed to build up above the filter bag.
It is also recommended that additional monitoring is conducted following moderate to extreme rainfall events, especially when preceding months have had little or no rainfall. This increased frequency of monitoring is necessary as there is a greater accumulation of surface contamination during low rainfall periods, which will then enter the unit with the higher volumes of runoff generated during a major rainfall event. It is also important to ensure that the units have not been damaged due to high pipe velocities.

Stormwater360 Operations and maintenance 9
3.2 Stormwater pit cover removal
3.2.1 Hinged pit grates
These are the steps for opening a hinged pit grate:
1 Insert the lifting hooks beneath the grate. (Position indicated in Photo 3)
2 Check hinge point is not damaged and debris is not caught in the hinge area.
3 Fully open pit grate, ensuring that the grate will stay in the open position without any external forces applied. Grates that do not remain open without being held should be removed or secured during cleaning or maintenance activities. Photo 4 indicates the grate being opened and grate resting freely in the open position, respectively.
Please note: Many cast iron hinges are not hinged securely (to enable the removal of the grate). This may result in the pit grate not being able to sit in an open position. Additionally the hinge pins may also be damaged or corroded, which may allow the grate to fall into the pit. Such pit grates can be removed using the method indicated below for non-hinged grates.

3.2.2 Non-hinged pit grates
To remove a non-hinged pit grate:
1 Place lifting hooks beneath grate, where possible in the four corners of the grate (see Photo 6). Concrete lids may have Gatic lifting points, a key arrangement or holes in the lid, which may require special equipment such as Gatic lifters
2 Position each person either side of the grate (see Photo 7)
3 Lift the grate, ensuring that good heavy lifting posture is used at all times
4 Place the grate on an angle on the gutter, to allow for the lifting hooks to be removed (see Photo 8)
5 For extremely heavy one-piece grates and concrete Gatic covers, insert the lifters in place and slide the lids back. Note some lids may still require two people

3.3 Cleaning methods
One of the following maintenance methods should be used for servicing EnviroPod Filters:
3.3.1 Cleaning using an inductor truck
Follow these steps to safely and efficiently clean the EnviroPod using an inductor truck:
1 Open gully pit (See Section 3.2)
2 Place the inductor hose over the material collected in the filter bag and switch on the inductor
3 Using the inductor hose, suck out all of the sediment, organic leaf material, litter etc. collected in the filter bag
4 Allow the filter bag to be sucked up into the inductor hose for a few seconds to allow for the filter mesh pores to be cleaned. Care is to be taken that there are no sharp edges on the inductor hose that can damage the filter bag
5 If material has built up around the overflows, use the inductor hose to clear the accumulated material
6 Remove filter bag from the pit
7 Sediment retained in the gully pit grate is to be removed
8 Back-opening channels are to be cleared of any debris to ensure flow is not hindered. This debris can also be collected using the inductor truck
9 All gully pit waste is to be removed from the pit
10 Check the EnviroPod unit (Section 3.4)
11 Check filter bag (Section 3.4)
12 Reinstate filter bag and gully pit lids
Photo 11 Cleaning an EnviroPod using the inductor method
3.3.2 Hand maintenance
To clean the EnviroPod manually by hand, follow these steps:
1 Open gully pit (See Section 1)
2 Place the lifting hooks in the lifting loops of the filter bag (See Photo 12)
3 For extremely heavy and overfilled bags either use a hydraulic lifting arm to lift the bag, or remove excess material using a shovel or similar piece of equipment. IES prefers the use of a post hole shovel, due to the reduced strain on the back when digging and the ability of the shovel to grab material vertically
4 Lift the bag vertically off the supporting frame, ensuring that no undue pressure is placed on the filter bag. (See Photo 13)
5 Lift the bag clear of the stormwater pit (See Photo 14)
6 Position the bag over the truck or other collection vehicle, taking hold of the loops at the base of the bag (See Photo 15 and Photo 16)
7 Lift and empty the filter bag by holding the bottom lifting loops only (See Photo 17)
8 Completely empty the filter bag (See Photo 18)
9 Brush the filter bag with a stiff brush to remove bound sediment from the filter pores
10 Check the EnviroPod unit (Section 3.4)
11 Check the filter bag (Section 3.5)
12 Reinstate filter bag, ensuring bag is installed the correct way (See Photo 19 and Photo 20)
13 Reinstate gully pit lids (See Photo 21 and Photo 22)

Photo 23 Check seals are pushed against the pit walls
3.4 Unit inspection
After the EnviroPod filter bag has been removed, emptied and cleaned, the following should be checked to ensure that the unit has not been damaged:
• All connections and joints should be checked and broken rivets replaced (See Photo 23)
• The plastic pit seals should be inspected for unit movement or damage (See Photo 24)
• The cage should be inspected for damage or movement.
The overflow diversion channels, and the area between the EnviroPod cage and pit wall should also be inspected for any accumulated debris. Any observed debris should be removed and disposed of off-site. Accumulated material within the outlet pipe may also need to be flushed.
If spare parts are required, Stormwater360 is able to provide these at a cost to the owner of the EnviroPod unit, although these parts may also be obtained from other suppliers.
Please note: If the units are not cleaned regularly, the mobilisation of material collected in the EnviroPod unit may occur. As such, cleaning of the units in accordance with this management plan is required. As this plan is based on observations and data collected during the monitoring period, ongoing adjustment of the cleaning frequency is generally required to improve the overall efficiency in the removal of collected material and prevent material overflow.
Photo 24 Check joining rivets (two piece unit shown above)
3.5 Filter bag inspection and rejuvenation
After the filter bags have been emptied and cleaned, they should be inspected to evaluate their condition. Given the nature of stormwater, the filter bag may become considerably clogged with fine sediment or damaged by various objects in stormwater as well as fauna. Sharp material such as sticks, combined with high velocity water and a large mass in the filter bag, can cause small tears in the filter material. Animals such as rats have also been known to chew through fine mesh filter bags located in gully pits near takeaway food outlets.
3.5.1 Clogged filters
Clogged filter bags can be cleaned using several different methods. If the techniques described in the general maintenance sections above do not adequately clean the filter bags, the following options should be considered:
• Using a stiff brush and a bucket of soapy water, scrub the filter bag surface.
• Remove filter bags from the pit and wash the bags using a high pressure water spray, taking care not to transfer the contamination elsewhere. Wastewater from the process should be collected and disposed of correctly.
• Remove the filter bags from the pits and the support rings and wash the bags in an industrial washing machine.
This final option typically results in the bags appearing like new, with no visible stain or pore clogging within the filter mesh.
Stormwater360 Operations and maintenance 15
Photo 25 Slightly clogged filter bag, indicated by the brown stain on in the centre of the bag
3.5.2 Damaged filters
Damaged filter bags can often be repaired, provided the damage is small. Small tears in the fabric may occur due to several reasons, however the overall strength and structure of the nylon fabric typically prevents small tears becoming much larger. Although the bag is unlikely to tear further, care must be used when cleaning torn bags so as not to spill the collected material into the pit.
Small tears may be repaired by either sewing the tear back together with additional fabric to increase the strength of the stitching, or by sewing a patch of the filter material onto the filter bag. If large tears are present, the filter bag may need to be replaced as it is no longer able to function as intended.
Photo 26 A clean used filter bag
3.6 Disposal of material
All gully pit wastes are to be taken off site and disposed of at a transfer station or similar approved disposal site. Stormwater sediments can contain lead, copper, zinc, mercury, hydrocarbons and PCBs, which are harmful to both humans and the receiving environment. Appropriate sampling and laboratory analysis may be required to classify the material as suitable for reuse, or disposal under appropriate local guidelines.
16 Stormwater360 Operations and maintenance
Spills and blockages can have an immediate impact on the performance of a stormwater management system, and can potentially result in serious damage to built infrastructure as well as the surrounding waterways and wetlands.
In these types of emergencies, it is important to act quickly to remediate the problem by removing affected sediment or clearing the cause of the blockage, so that the system can resume normal and effective functioning as soon as possible.
4.1 Spill procedures
In the event of a spill discharging into any gully pit, all sediment is to be extracted and the filter bags are to be removed and replaced with rejuvenated filter bags. Normal operation procedures apply to additional cleaning as a result of spills.
4.2 Blockages
In the unlikely event of surface flooding around a gully pit fitted with an EnviroPod the following steps should be carried out:
1 Check EnviroPod overflow bypass. The EnviroPod filter has been designed with an overflow mechanism built into the filter box. If surface flooding still exists, check the overflow slots underneath the rubber seal. If debris is lodged in the overflow slots it can be easily cleared by hand or a steel rod.
2 If overflow is clear and surface flooding still exists remove EnviroPod and check outlet pipe for blockages.
3 Removal of the EnviroPod may be difficult if the filter is clogged and the EnviroPod is holding water. If the filter is clogged, brush the sidewalls of the filter with a yard broom or similar. This will dislodge particles trapped at the interface allowing contained water to flow through the filter.
4 If the outlet pipe is blocked, it is likely that a gully sucker truck will be required to unblock it. Debris should be removed from the EnviroPod with the gully sucker truck before removal of the EnviroPod filter. If a gully sucker truck is not available and the EnviroPod needs to be removed by hand, follow the steps below:
a Remove excess debris by hand or brush the side of the filter.
b Lift and place filter ring through the filter box and into cage.
c Remove Filter box.
d Lift cage containing filter bag and ring out of the pit.
e Unblock outlet pipe.

The Stormwater Management StormFilter®
For almost two decades the Stormwater Management StormFilter ® has helped meet the most stringent stormwater quality requirements.
The system has been continually tested and refined, to ensure it achieves maximum reliability and performance.
As a best management practice (BMP) system, it removes the most challenging target pollutants – including fine solids, soluble heavy metals, oils and total nutrients (including soluble) – by using a variety of media to achieve site-specific pollutant removal objectives.
18 Stormwater360 Operations and maintenance
1.1 Description
StormFilter is a passive, flow-through stormwater filtration system consisting of vaults that house rechargeable cartridges filled with a variety of filter media, and is installed in-line with storm drains. The StormFilter works by passing stormwater through media-filled cartridges, which trap particulates and adsorb materials such as dissolved metals and hydrocarbons. After being filtered through the media, the treated stormwater flows into a collection pipe or discharges into an open channel drainage way. StormFilter is offered in three different configurations: cast-in-place, precast and linear. The precast and linear models utilise pre-manufactured vaults. The cast-in-place units are customised for larger flows and may be either covered or uncovered underground units.
1.2 Operation
1.2.1 Purpose
The StormFilter is a passive stormwater filtration system designed to improve the quality of stormwater runoff from the urban environment before it enters receiving waterways.
Through independent third party studies, it has been demonstrated that the StormFilter is highly effective for treatment of first flush flows, and fast-paced flows, during the latter part of a storm. In general, StormFilter’s efficiency is highest when pollutant concentrations are highest. The primary target pollutants for removal are: sediments (TSS), soluble metals, soluble phosphorus, nitrates, and oil and grease.
1.2.2 Sizing
The StormFilter is typically sized to meet design water quality objectives, which are subject to legislation regulated by local government authorities and other relevant environmental bodies. MUSIC modelling software is used to determine pollutant loads from a site, influenced by a number of factors such as site area, imperviousness and land use. Pollutant load reduction capabilities, based on third party testing, allows the number of StormFilter cartridges required to achieve the relevant objectives to be established. Cartridges are designed to treat a peak flow between 0.7 and 1.6 litres/second, depending on the cartridge size used. For example, 10 standard sized cartridges (460mm) are able to treat 11 L/s, as each filter can treat 1.1 L/s.
Because of the highly porous nature of the granular filter media, the flow through a newly installed cartridge is restricted to 1 L/s (average 460mm), using a restrictor disc, to ensure adequate pollutant-media contact time.
Photo 27 Filter cartridge
StormFilter® overview
Stormwater360 Operations and maintenance 19
1.2.3 Basic function
The StormFilter is designed to siphon stormwater runoff through a filter cartridge containing media. The variety of media available can be designed to act as a mechanical filter to remove sediments, as an ion exchanger to remove dissolved heavy metals, and as an absorber to remove oils and greases.
1.2.4 Priming system function
The treated stormwater collects in the centre tube of the cartridge, which is equipped with a self-priming siphon system. (Figure 1 illustrates this system.) The key component of the system is the plastic float, consisting of a ball located at the base leading up to a larger portion, which provides increased buoyancy. Initially the ball rests in a seat, effectively closing off the port to the drainage manifold.
As a result, the filter fills the centre drainage tube until the water level has risen high enough to purge the air from the filter cartridges and displaces the float. At a water depth of 22 inches the float pulls loose and allows the filtered water to drain out through the manifold. This effectively “primes” a siphon within the drainage tube and greatly increases the potential across the filter. The priming system increases StormFilter’s ability to be loaded with sediment. A related feature is the cartridge “hood”. This hood maintains the siphon effect by preventing air from being drawn into the cartridge until the external water level drops below the bottom of the hood.
Cartridges are connected to the manifold with a plastic connector. These can be either quarter turn connectors or in the older systems, threaded connectors.
StormFilter is also equipped with flow spreaders that trap floating debris and surface films, even during overflow conditions. Depending on individual site characteristics, some systems are equipped with high and/or low flow bypasses. High flow bypasses are installed when the calculated peak storm event generates a flow that overcomes the overflow capacity of the system. This is especially important for precast systems. Low flow bypasses are sometimes installed to bypass continuous inflows caused by ground water seepage, which usually do not require treatment. All StormFilter units are designed with an overflow. The overflow operates when the inflow rate is greater than the infiltration capacity of the filter media.
1.2.5 Maintenance overview
The primary purpose of the StormFilter is to filter out and prevent pollutants from entering our waterways. Like any effective filtration system, these pollutants must be removed periodically to restore the StormFilter to its full efficiency and effectiveness. Maintenance requirements and frequency are dependent on the pollutant load characteristics of each site. To assist the owner with maintenance issues, Stormwater360 provides detailed Operation and Maintenance Guidelines with each unit.
Stormwater360 can provide maintenance services completely, or in part. Available services include tracking of installed systems, advising the system’s owner of maintenance needs, and notification of the regulatory agency once the system has been maintained.
Maintenance is usually performed in the dryer periods to rejuvenate the filter media and prepare the system for the next rainy period. Maintenance activities can also be required in the event of a chemical spill or excessive sediment loading due to site erosion or extreme storms. It is good practice to inspect the system after severe storm events.

20 Stormwater360 Operations and maintenance
To ensure the optimal and ongoing performance of the StormFilter, the system requires systematic inspection, cleaning and maintenance. This maintenance regime falls into two categories – ongoing minor inspection and maintenance, and major cleaning and maintenance. The maintenance frequency is largely determined by the conditions of each site, and the amount of sedimentation in the stormwater runoff that flows through the system. Unexpected events such as chemical spills, erosion or extreme storm activity require immediate inspection of the system, together with removal of debris or contaminated sediment, and where appropriate, replacement of the media cartridges.
While some maintenance activities can be completed by hand, others require specialised equipment such as an inductor truck with a vacuum hose. In all cases, it is important that maintenance staff are properly trained in the functioning of the StormFilter system and have a good knowledge of the correct procedures for disposing contaminated sediment as well as the methods for removing and installing StormFilter media cartridges.
At all times, appropriate safety equipment must be used, and Occupational Health And Safety (OH&S) guidelines adhered to.
StormFilter® maintenance and performance expectations
Stormwater360 Operations and maintenance 21
2.1 Types of maintenance
Presently, procedures have been developed for two levels of maintenance:
• Inspection and/or minor maintenance
• Major maintenance.
Inspection/minor maintenance activities are combined since the minor maintenance does not require special equipment and typically little or no materials are in need of disposal.
Inspection/minor maintenance typically involves opening the flow restricting valves (to pre-set levels) and cleaning up vegetation and debris. Major maintenance typically includes cartridge recharging. Major maintenance may involve disposal of materials that require consideration of regulatory guidelines. Depending on the particular unit configuration and equipment used, major maintenance may require an understanding of OSHA rules. Table 1 summarises the primary activities associated with StormFilter maintenance.

22 Stormwater360 Operations and maintenance
2.2 Maintenance activities
2.2.1 Maintenance activity timing
Two scheduled inspections/maintenance activities should take place during the year. During the minor maintenance activities (routine inspection, debris removal), the type of major maintenance required is determined and, if required for disposal, samples of the sediments and media are obtained.
The next scheduled date is to perform major maintenance activities (replacement of the filter cartridges and associated sediment removal). In addition to the scheduled activities, it is important to check the condition of the filter after major storms to check for damage caused by high flows and to check for high sediment accumulation, which may be caused by localised erosion in the drainage area. It may be necessary to adjust maintenance activity scheduling depending on the actual operating conditions encountered by the system.
2.2.2 Maintenance activity frequency
The primary factor controlling timing of maintenance for the StormFilter is sedimentation. A properly functioning system will remove solids from water by trapping these particulates within the porous structure of the media. The flow through the system will naturally decrease as more and more solids are trapped. Eventually the flow through a system will be low enough to require replacement of the cartridges. Sediment should be removed from upstream trapping devices on an as-needed basis to prevent material from being re-suspended and discharged to the system.
Site conditions greatly influence maintenance requirements. StormFilter units located in areas with erosion or active construction should be inspected and maintained more often than those in fully established areas. The maintenance frequency may be adjusted as additional monitoring information becomes available during the inspection program. Areas that develop known problems should be inspected more frequently than areas that demonstrate no problems, particularly after large storms. Ultimately, inspection and maintenance activities should be scheduled based on the historic records and characteristics of an individual filter.
2.3 Maintenance crew requirements
Table 2 lists the anticipated crew requirements for maintenance operations. Removal of water and sediments during major maintenance activities can be accomplished using either a pump and water truck or a vacuum truck. All
applicable occupational health and safety (OH&S) and disposal regulations should be followed. A general description of the maintenance activities follows.

2.4.1 Minor maintenance/inspection (twice a year)
Minor maintenance typically will involve the steps below, however if it appears that a spill of some type has occurred, the local hazard control agency and Stormwater360 should be notified immediately.
Steps for Minor Maintenance/Inspection
1 Maintenance to be performed by a skilled worker familiar with StormFilter units.
2 If applicable, set up safety equipment to protect pedestrians from fall hazards presented by open access covers. Also set up appropriate safety equipment for work near roadways.
3 Inspect the external condition of the unit and take notes concerning defects/problems.
4 Open the access covers to the vault and allow the system to air out for 5-10 minutes.
5 Without entering the vault, inspect the inside of the unit, including components.
6 Take notes about the external and internal condition. This includes inspecting pit penetrations, walls, lids, ladders and grates etc.
7 Give particular attention to recording the level of sediment build-up on the floor of the vault and on top of the internal components. If flow is occurring, note the level of water and estimate the flow rate per drainage pipe. Record all observations.
8 Remove large loose debris and litter using a pole with a grapple or net on the end.
9 Close and fasten the access cover, and remove safety equipment.
10 Finally, make notes about the local drainage area relative to ongoing construction, erosion problems, or high loadings of other materials to the system.
In the case of a spill, workers should abort maintenance activities until the proper guidance has been obtained.
24 Stormwater360 Operations and maintenance
2.4.2 Major maintenance inspection (once a year)
The primary goal of the major maintenance inspection is to assess the condition of the cartridges relative to the level of sediment loading. It may be desirable to conduct this inspection during a storm to observe the relative flow through the filter cartridges. If the submerged cartridges are severely plugged, large amounts of sediments should be present and very little flow will be discharging from the drainage pipes. It is likely that the cartridges need to be replaced. Major maintenance inspection will typically involve the steps below. However, if it appears that a spill of some type has occurred, the local hazard control agency and Stormwater360 should be notified immediately. In the case of a spill, the worker should abort maintenance activities until the proper guidance has been obtained.
Steps for Pre-Major Maintenance Inspection
1 Maintenance to be performed by a skilled worker familiar with StormFilter units.
2 If applicable, set up safety equipment to protect pedestrians from fall hazards presented by open doors. Also, set up appropriate safety equipment for work near roadways.
3 Inspect the external condition of the unit and take notes concerning defects/problems.
4 Open the access covers to the vault and allow the vault to air out for 5-10 minutes.
5 Without entering the vault, give the inside of the unit, including components, a general condition inspection.
6 Take notes about the external and internal condition.
7 Give particular attention to recording the level of sediment build-up on the floor of the vault, and on top of the internal components.
8 Remove large loose debris and litter using a pole with a grapple or net on the end.
9 If the visit is during a storm, make the flow observations discussed above.
10 Close and fasten the access cover, and remove safety equipment.
11 Make notes about the local drainage area relative to ongoing construction, erosion problems, or high loading of other materials to the system.
12 Review the condition reports from the previous minor and major maintenance visits and schedule for cartridge replacement if needed.
2.4.3 Major maintenance: sediment removal and cartridge replacement (and emergency)
Major maintenance/filter cartridge replacement typically involves the steps below. However, if it appears that a spill of some type has occurred, the local hazard control agency and Stormwater360 should be notified immediately. In the case of a spill, the worker should abort maintenance activities until the proper guidance has been obtained.
Depending on the configuration of the particular system, a worker may be required to enter the vault to perform some tasks. If vault entry is required, OH&S rules for general confined space entry must be strictly adhered to. Filter cartridge replacement should occur during dry weather and it may be necessary to plug the filter inlet pipe if base flows exist. Standing water present in the vault should be regarded as polluted and contained during this operation by temporarily capping the manifold connectors.
Please note: Confined space entry may be required on StormFilter systems. In this case, please ensure that appropriate Confined Space entry training and subsequent certification has been undertaken and is valid, and work procedures are strictly adhered to. If you are unsure, do not enter the vault and contact Stormwater360 immediately.

Steps For Cartridge Replacement Maintenance
1 Depending on the particular unit, one or two utility workers and a hauling truck operator will deliver the replacement cartridges to the site. Information concerning how to obtain the replacement cartridges is available from Stormwater360.
2 If applicable, set up safety equipment to protect pedestrians from fall hazards presented by open doors. Also, set up appropriate safety equipment for work near roadways.
3 Inspect the external condition of the unit and take notes concerning defects/problems.
4 Open the doors to the vault and allow the system to air out for 5-10 minutes.
5 Without entering the vault, give the inside of the unit, including components, a general condition inspection.
6 Make notes about the external and internal condition.
7 Give particular attention to recording the level of sediment build-up on the floor of the vault and on top of the internal components.
8 Ensuring safe working procedures are met, off load the replacement cartridges (16-39kgs each) and set aside.
9 Remove the top cap (threaded), upper seal and float from the cartridge. Repeat procedure for every cartridge within StormFilter vault. Place items in a large plastic container to be lifted form the vault.
10 Using a cordless drill and 8mm hex head, remove the three screws located around the top perimeter of the cartridge hood. Place screws in the large plastic container and, once full or completed, remove plastic container from vault.
11 Move the vacuum truck near the StormFilter vault on the down-wind side. Be sure that the truck is not too close to the vault so that fumes will not enter the vault. Make sure that the last 500mm of the nozzle is approximately 100-125mm in outside diameter.
12 Feed vacuum nozzle into cartridge bay and start vacuum truck. Remove cartridge hood and place nozzle directly onto filter media. Completely remove media from each cartridge and repeat process for every cartridge in vault.
13 Once completed disconnect cartridges from vault floor and place hood back on cartridges
14 Using the appropriate lifting cap, attach the cable and remove the cartridge (up to 10kgs. each) from the vault. It is strictly prohibited to have personnel standing under suspended cartridges. Care must also be used to avoid damaging the cartridges during removal and installation. The cost of repairing components damaged during maintenance will be the responsibility of the owner unless Stormwater360 is performing maintenance activities and damage is not related to discharges to the system.
15 Set the used cartridge aside or load onto the hauling truck.
16 Repeat steps 14 to 15 until all cartridges have been removed.
17 Remove deposited sediment from the floor of the vault. This can be accomplished by using the vacuum truck
18 Once the sediments are removed, it is necessary to assess the condition of the vault, particularly the manifold and the connectors. These are short sections of 2-inch schedule 50 PVC, or threaded schedule 80 PVC that should protrude above the floor of the vault. If required, apply a light coating of FDA approved silicon grease to the outside of the exposed portion of the connectors. This ensures a watertight connection between the cartridge and the drainage pipe. Replace any damaged connectors.
19 Using the boom, crane, or tripod, lower and install the new cartridges (typically 30kg for standard 460 cartridges). Once again, take care not to damage connectors.
20 Close and fasten the access cover, and remove safety equipment.
21 Make notes about the local drainage area relative to ongoing construction, erosion problems, or high loadings of other materials to the system.
22 Finally, dispose of the residual materials in accordance with applicable regulations. Make arrangements to return the used cartridges to Stormwater360.
26 Stormwater360 Operations and maintenance
2.4.4 Related maintenance activities (performed on an as-needed basis)
StormFilter units are often just one of many components in a more comprehensive stormwater drainage and treatment system. The entire system may include catch basins, detention vaults, sedimentation vaults and manholes, detention/retention ponds, swales, artificial wetlands, and other miscellaneous components. In order for maintenance of the StormFilter to be successful, it is imperative that all other
components be properly maintained. The maintenance/repair of upstream facilities should be carried out prior to StormFilter maintenance activities. In addition to considering upstream facilities, it is also important to correct any problems identified in the drainage area. Drainage area concerns may include: erosion problems, heavy oil and grease loading, and discharges of inappropriate materials.
2.5 Typical equipment required for maintenance activities
Typical equipment required for conducting maintenance is shown in Table 3. Some of the materials listed are suggestions rather than requirements. It should be noted that there is more than one way to accomplish some tasks. Owners
with available labour and equipment resources may desire to use alternative methods. However, it is advisable that guidance from Stormwater360 be obtained prior to using alternative techniques.

Stormwater360 Operations and maintenance 27
2.6 Material Disposal
The accumulated sediment found in stormwater treatment and conveyance systems must be handled and disposed of in a manner that will not allow the material to affect surface or ground water. It is possible for sediments to contain measurable concentrations of heavy metals and organic chemicals (such as pesticides and petroleum products). Areas with the greatest potential for high pollutant loading include industrial areas and heavily travelled roads. Sediments and water must be disposed of in accordance with all applicable waste disposal regulations.
It is not appropriate to discharge these materials back to the stormwater drainage system. Part of arranging for maintenance to occur should include coordination of disposal of solids (landfill coordination) and liquids (municipal vacuum truck decant facility, local wastewater treatment plant, on-site treatment and discharge). Owners should contact the local public works department and inquire about how the department disposes of their street waste residuals. Stormwater360 will determine disposal methods or reuse of the media contained in the cartridges. If the material has been contaminated with any unusual substance, the cost of special handling and disposal will be the responsibility of the owner.

TECHNICAL MEMORANDUM To: Ronald Suarez
From: Joshua May, David Colledge
CC: Ricardo Ramirez, Andy Lees
Date: 10 March, 2016
Re: 4 to 10 Hoey Street, Sarina QLD - Water and Sewer Network Capacity Assessment
INTRODUCTION
Mackay Regional Council (MRC) issued an Information Request (IR), dated 9 November 2015, for a
Material Change of Use (MCU) application for the proposed development at 4 to 10 Hoey Street,
Sarina QLD. The development will comprise of removing 8 existing aged care units and constructing
an additional 24 aged care units. Please refer to Attachment 1 for site layout plan.
A component of MRC’s IR included the following:
“2. Water & Sewerage
a. Calculate the sewer and water demands generated for the proposed development and for the
ultimate development.
b. Determine if the existing water and sewer infrastructure will have capacity for the proposed &
ultimate developments.
c. Provide details of any firefighting requirements associated with the proposed & ultimate
developments.”
On behalf of Suarez Drafting and Design Pty Ltd, this memo has been prepared to address Item 2 of
the IR issued by MRC.
DEMAND ASSESSMENT
A demand assessment of the site was undertaken to determine the approximate water and sewage
volumes attributed to the proposed development. The associated demands were calculated using
MRC’s adopted Equivalent Persons (EP) unit rates and standard Average Day Demands (ADD) for water
and sewage (300 L/EP/day and 230 L/EP/day respectively).
Please refer below for the demand estimations of the development.

PROPOSED CONNECTION POINTS
The site connection points will potentially be located on the existing water and sewer mains along
Brewers Road. Please refer Attachment 2 for further details.
FIREFIGHTING REQUIREMENT
As per MRC’s service standards, the following firefighting requirements are to be achieved.
15 L/s at 2/3 peak hour; and
12 m residual pressure, at Council hydrants.
INFORMATION REQUEST
On behalf of Suarez Drafting and Design Pty Ltd, H2One Pty Ltd requested MRC to undertake a water
and sewer network capacity assessment, using the information provided in this memorandum, and
submitting the outcome to the undersigned below.
CONCLUSION
To address Mackay Regional Council’s (MRC) Information Request (IR) dated 9 November 2015, the
details within this technical memorandum were issued to MRC. Based on the calculated demands of
the proposed development, MRC completed a hydraulic analysis to confirm the capacity of the existing
infrastructure to service the Material Change of Use (MCU) for the proposed development site.
Analysis showed that based on the estimated site demand of 20 Equivalent Persons (EP), the proposed
development can be serviced from the existing network whilst meeting the required MRC Desired
Standards of Service for water and sewer. Water and sewer infrastructure upgrades are therefore not
required.
Please refer Attachment 3 for MRC correspondence.
Yours Sincerely,
Joshua May Senior Water and Sewer Network Engineer H2One Pty Ltd E [email protected] P 0423 264 390 W h2one.com.au
