1 Introduction

SLR Consulting Australia Pty Ltd (SLR) was retained by South East Water to conduct a predictive noise impact assessment of the proposed water recycling plant which will service the Aquarevo Estate in Lyndhurst.

The assessment will form part of South East Water’s Works Approval request to the Victorian Environment Protection Authority (EPA Victoria).

The objectives of this study were to:

1. Determine noise limits applicable at the closest noise sensitive (residential premises) in accordance with the Victorian Environment Protection Authority (EPA Victoria) policy document ‘State Environment Protection Policy (Control of noise from commerce, industry and trade) No. N-1’ (SEPP N-1).

2. Predict noise from the proposed facility to these dwellings based on provided noise data, and plant layout information.

3. Assess noise from the facility at the nearest potentially affected noise sensitive receivers to determine compliance or otherwise. Where the predicted noise levels exceed relevant SEPP N-1 noise criteria, conceptual noise control advice will be provided.

2 Project Description and Site Details

2.1 Project Description

South East Water, in partnership with Villawood Holdings, is building a residential development at Evans Road, Lyndhurst, called Aquarevo. Aquarevo is being implemented as one of the most water and energy efficient developments of its type in Australia. It includes features to use Class A recycled water and rainwater at each house to reduce drinking water consumption by up to 70%. In addition, each house will incorporate solar panels and provision for a solar battery, that would reduce use of mains power by up to 80%.

Aquarevo also includes a pressure sewer system, whereby each house has a 1,000 L pod with macerating pump to collect and discharge wastewater. Each pod is monitored and controlled by South East Water’s propriety OneBox+® controller, which determines at what point the pump will be activated. This can lead to significant smoothing out of flows through the sewer system. The pressure sewer shall discharge to the local water recycling / Waste Water Treatment Plant (WWTP) where it will be treated to Class A recycled water.

The Masterplan is reproduced in Figure 1 which shows the general location of the Aquarevo Development and proposed water recycling plant in relation to existing residential developments

For the first time in Australia the recycling plant will incorporate the use of an Organica Food Chain Reactor (FCR) process, which has a low energy footprint and contains odour within the structure. Widely used in urban settings across Europe and China, this state-of-the-art treatment process combines natural and artificial root environments to provide a highly robust and energy efficient treatment process with a low carbon footprint.

South East Water intends to build the local water recycling plant on-site, to treat waste from the ultimate 460 lot development (230 kL/day). Following an Expression-of-Interest process in 2014 / 2015, Hydroflux was selected to construct the Organica FCR (known as a Bluehouse). The Bluehouse can begin construction when there is at least 40% of the design flow (this equates to approximately 180 houses on line), which is forecast to occur by July 2020.

The Organica Bluehouse is a pre-fabricated sewage treatment system whereby all process equipment, instruments and controls are integrated into a series of modified shipping containers, located within a Glasshouse structure. The Bluehouse consists of a pre-treatment, aeration and clarification zone. Screenings and grit are removed in the pre-treatment area using a packaged inlet works system. The aerated reactor consists of the Organica FCR Cascade process, with six reactors operating in series. The first reactor is an anoxic zone, followed by five aerobic zones. The aeration demand is controlled by air supplied using positive displacement blowers and a fine bubble diffused aeration system. The excess biomass wasted from the Bluehouse will be pumped to the adjoining 1200 mm Cranbourne Main Sewer.

The Class C effluent produced from the Bluehouse shall be treated to Class A through an additional tertiary system including Ultra-filtration, UV Sterilisation, Storage and post chlorination. Backwash from the Class A process shall be directed to the trunk sewer for disposal. A process flow diagram illustrating the procedure is provided in Figure 2.

2.2 Location

The Aquarevo Bluehouse FCR will be installed at the greenfield site 183 Brookwater Pde, Lyndhurst. The street backs onto the Cranbourne railway line to the east, which separates the development from the Cranbourne Wetlands Nature Reserve. Major roads in the area consist of the South Gippsland Hwy which is located approximately 1 km to the east, Thompsons Rd roughly 1.1 km south of the site, and Western Port Highway approximately 1.2 km to the west. Evans Rd which runs in a north – south direction, connecting both the South Gippsland Fwy and Thompsons Rd is approximately 400 m to the east; however, this road carries significantly less traffic.

It is understood that construction of the development began in early 2019, with the completed residential dwellings mostly located to the south of the site north of Noremac Grove (see Figure 4).

Construction of the residential area surrounding the proposed WWTP has not yet commenced. However, it is understood that the closest residential properties that could potentially be affected by noise from the facility will be located approximately 25 m both north (at 185 Brookwater Pde) and south (at 181 Brookwater Pde) of the Aquarevo Bluehouse building.

3 State Environment Protection Policy No. N-1

Residents in metropolitan Melbourne are protected from excessive noise from commerce, industry and trade under the provisions of Victorian Environment Protection Authority (EPA Victoria) policy document ‘State Environment Protection Policy (Control of noise from commerce, industry and trade) No. N-1’ (SEPP N-1).

SEPP N-1 provides a method for determining noise limits applicable at a noise sensitive area (i.e. a residential dwelling) against which noise from the commercial premises can be assessed.

Different noise limits are determined for different periods, with the most onerous normally applicable during night time. Definitions of the different time periods are shown in Table 1.

Table 1 SEPP N-1 definitions of daytime, evening and night-time periods

Period Day Time

Daytime Monday to Friday

Saturday

07:00h to 18:00h

07:00h to 13:00h

Evening Monday to Friday

Saturday

Sunday and public holidays

18:00h to 22:00h

13:00h to 22:00h

07:00h to 22:00h

Night time Monday to Sunday 22:00h to 24:00h

00:00h to 07:00h

Under the Policy, the noise limit at a residential dwelling is based on the land use zoning of the surrounding area as defined by the relevant planning scheme, and the measured background noise levels where those levels are particularly high or low.

To determine whether noise emissions from commercial premises are excessive under the Policy, the noise limit is compared with the effective noise level. The effective noise level is the level due to the industry measured at a residential dwelling or noise sensitive location, which has had adjustments applied to it to account for certain characteristics such as tone, impulse, duration, intermittency, etc. which may make the noise more or less annoying to residents than the measured level alone would indicate.

3.1 SEPP N-1 Noise Criteria

3.1.1 Zoning Levels

To determine the SEPP N-1 noise limit at the closest residential dwellings the zoning level was determined. The zoning level provides an indication of the ratio of residential to commercial or industrial land usage around the sensitive receiver. The method for determining the zoning level is provided in SEPP N-1 and involves the drawing of 140 m and 400 m diameter circles centred on the receiver location.

The surrounding land includes:

• General Residential Zone 1 (GRZ1): For residential land on both sides of the railway alignment, including the Organica FCR site.

• Public Use Zone 5 (PUZ4): For the Melbourne to Cranbourne railway alignment.



For the determination of influencing factors and zoning levels PUZ4 is classified as Type 2 usage, with GRZ1 classified as Type 1.

Appendix A illustrates the zoning circles used for calculation of zoning levels (shown in Table 2) for the closest, most exposed dwelling south of the site. Where the background noise at the receiver location falls within the outlined ‘neutral range’ the resultant SEPP N-1 noise limits are based on the zoning levels.

Table 2 Calculated SEPP N-1 Zoning Levels for 181 and 185 Brookwater Parade, Lyndhurst

Time of Day Zoning Level, dBA(1) L90(2) Range to achieve neutral condition, dBA

Saturday (1300h-1800h) 46 37 < Neutral < 43

Sunday (0700h-1800h) 46 37 < Neutral < 43

Evening (1800h-2200h) 46 37 < Neutral < 43

Night (2200h-0700h) 41 32 < Neutral < 41

3.1.2 Background Noise Levels

As the facility will operate on a 24 hours per day, 7 days per week basis, background noise measurements were taken during the critical night / early morning period between 3:00 am and 4:00 am when background noise levels are generally at their lowest.

Noise measurements were taken using a Rion NA-28, Type-1 1/3 Octave Band Sound Level Meter (Serial No.: 01181098) which was calibration checked using a Brüel&Kjær 4230 calibrator (Serial No.: 3002675) immediately before and after the noise survey. All equipment used carries current NATA certification and complies with applicable calibration requirements.

The attended noise measurement results taken at locations deemed representative of the completed development site are shown in Table 3. Weather conditions during the survey were calm, dry, and slightly overcast.

(1) dBA The overall level of a sound is sually expressed in terms of dBA, which is measured using a sound level meter with an “A-weighting”

filter. This is an electronic filter having a frequency response corresponding approximately to that of human hearing

(2) L90 The noise level exceeded for 90% of the sample period. This noise level is described as the average minimum background sound

level (in the absence of the source under consideration), or simply the background noise level.

- Measured baseline noise levels noticeably quieter ~27 to 28 dBA

- Periodic smooth flowing traffic on Thompsons Rd ~30 to 35 dBA

- Intermittent large trucks ~37 to 52 dBA

3.1.3 SEPP N-1 Noise Limits

The measured background noise data was used in conjunction with the land use zoning to determine the applicable SEPP N-1 noise limits. Given noise from the frogs (as measured closer to the development site) could be seasonal in nature, the lower background measurement results from the intersection of Brookwater Pde and Colandy Cl were adopted.

The derivation of the noise limit is summarised in Table 4.

Note: Background noise measurements were not taken during the day and evening periods when applicable zoning levels are significantly higher.

4 Assessment of Mechanical Plant Noise

In order to determine the noise levels at the nearest residential receivers, a noise model was prepared using SoundPlan 8.1 noise modelling software.

Noise modelling of the proposed operations used the ISO 9613 algorithm as implemented in the SoundPLAN noise modelling package. Elevation for the site was assumed flat ground, with other inputs to the model including noise source data from equipment on site (see Table 5), ground cover, shielding by barriers / residential property boundaries, and/or adjacent buildings and atmospheric information.

(3) Leq The equivalent continuous noise level. It is defined as the steady sound level that contains the same amount of acoustical energy

as the corresponding time-varying sound.



4.1 Noise Sources

SLR was provided with general noise data for the proposed significant plant items that will be used on site.

The input noise data for the dominant mechanical plant items is provided in Table 5

Note A: Estimated SWL based off conformal area of blower, assuming SPL < 75 dBA at 1m from enclosure (supplier data)

Note C: Estimated SWL based off 3x pumps, assuming SPL for each pump SPL < 75 dBA at 1m (supplier data)

Note D: Estimated SWL based off 3x pumps, assuming SPL for each pump SPL < 50 dBA at 1m (supplier data)

The motors associated with the Huber Minicop © spiral screen located within the inlet works shipping container will also generate noise. However, given the low noise output from this plant (rated by the manufacturer at less than 40 dBA at 1 m), with the equipment located inside an enclosed steel room, and generally only operated for 2 hours / day, any contributions from this plant will be negligible. The only mechanical plant associated with the water recycling plant that will be installed outdoors is the Soliquator, which is stationary, has no moving parts, and therefore understood to create no noise.

A Site plan and elevation drawing showing the layout of the facility is provided in Figure 5. Figure 6 shows the equipment plant layout and the mechanical container which houses the blowers can clearly be seen (Organica Drawing M-012-001, dated 8 December 2016).

4.2 Noise Modelling Assumptions

To predict noise from the Aquarevo Bluehouse WWTP, predictions were made to determine the break-out noise from the mechanical shipping container, and resultant reverberant noise levels inside of the Glasshouse.

The predicted noise levels assume a 0.5m x 0.5m square opening (0.25 m²) from the mechanical shipping container to the Glasshouse for intake air purposes. The resultant noise inside the Glasshouse area (as dominated by noise break-out through the hole) was 72 dBA.

The predicted noise levels were input to the SoundPLAN (Version 8.1) noise modelling package to predict the resultant noise levels at the closest residential receptors.

The noise model also assumes the external Glasshouse structure (as part of the Bluehouse) is constructed of 6 mm thick Perspex (Rw = 26 dB), with the louvres on the top of the southeast wall assumed to be open to the outside (i.e., NOT acoustically treated) with dimensions of 0.8 m x 15 m facing the closest dwelling to the south.

5 Noise Modelling Results

5.1 Unmitigated (as-is) Condition

Table 6 shows the predicted noise levels from the operation of the proposed facility for typical operations. A noise contour plot showing the predicted noise levels to the surrounding residential area is shown in Appendix C, Map 1.

Table 6 Predicted Noise Levels – Aquarevo Bluehouse WWTP – Unmitigated Options

Receiver Noise Level, Leq dBA SEPP N-1 Noise Limit, dBA, Leff Compliance Status

Day Evening Night

North 185 Brookwater Pde 36 52 46 38 Y / Y / Y

South 181 Brookwater Pde 49 52 46 38 Y / N / N

From Table 6 it can be seen that the predicted noise levels at 181 Brookwater Pde (the closest dwelling to the south) exceed the night-time SEPP N-1 noise criteria by up to 11 dBA, and the evening noise limit (assumed to be in the neutral / ‘zoning’ range) by 3 dBA. Noise levels at this location are significantly louder than those predicted to the north due to the orientation of the Glasshouse, with the louvres at the top of the southeast wall (effectively providing a 12 m² opening) facing this dwelling.

There is potential for noise levels at proposed dwellings to the southwest (opposite Brookwater Pde) to also exceed the SEPP N-1 Night time noise limit by a small margin. As per the dwelling to the south, noise levels at these properties would also be dominated by break-out noise from the mechanical container, transmitted through the open louvres. Assuming mitigation treatments are implemented to ensure night time compliance with SEPP N-1 noise limits at the most exposed dwelling to the south (i.e., 181 Brookwater Pde), the transmitted noise levels at all other dwellings will also comply.

The noise modelling results indicate that noise from the facility will comply with SEPP N-1 noise criteria at most other dwellings, including the property to the north at 185 Brookwater Pde.



5.2 Mitigated Conditions

The noise model was updated to include silencing on the penetrations between the mechanical plant shipping container and the main glasshouse. The silencing assumes the following transmission loss (TL - see Table 7) which is based off a 500 mm x 500 mm, 1.5 m long internally lined duct w/ 50 mm thick absorptive insulation.

Table 7 Minimum Insertion Loss of ~0.25 m² opening from Shipping Container to main Glasshouse, dB

-2 -3 -6 -17 -16 -14 -11 -10

With the above acoustic treatment, the reverberant noise level inside the Glasshouse area was reduced from 72 dBA to 61 dBA.

The predicted noise levels with the above noise control incorporated into the design are provided in Table 8.

Day Evening Night

North 185 Brookwater Pde 27 52 46 38 Y / Y / Y

South 181 Brookwater Pde 38 52 46 38 Y / Y / Y

From the results presented above it is evident that with appropriate noise control, noise from the Aquarevo Bluehouse FCR is predicted to comply with the most onerous night time noise criteria at all receptor locations.



6 Conclusion

SLR Consulting Australia Pty Ltd (SLR) was retained by South East Water to assess noise levels from the proposed operation of the Hydroflux Bluehouse Waste Water Treatment Plant, which will serve the proposed 410 dwelling Aquarevo Residential Development in Lyndhurst.

Relevant noise limits according to the EPA Victoria SEPP N-1 noise criteria have been determined and noise from the facility modelled.

Noise emissions from the existing facility have been predicted to comply with the most critical night-time noise limits at all future surrounding sensitive residential dwellings, provided sufficient noise control is included to any penetrations between the mechanical plant shipping container and the enclosing Glasshouse.

The assessment is based on the following assumptions which must be maintained:

1. Acoustic Silencer to the penetration between the mechanical container and Glasshouse to achieve performance as per Table 7. Note: if larger or additional penetrations are to be provided, these will need to be acoustically treated and the attenuation performance revised.

2. Any access doors to include perimeter compression seals.

3. Sound Power Levels of equipment as nominated in Table 5 are to be achieved (or the Sound Pressure Level as per manufacturer / supplier data at 1 m).

4. The Glasshouse structure is to be built of minimum 6 mm thick Perspex, with no additional openings apart from the 15 m x 0.8 m louvres.

In order to ensure noise from the facility complies with SEPP N-1 noise limits, it is recommended that a compliance noise survey is undertaken after the facility is online in mid-2020.

Assuming noise complies with the most onerous SEPP N-1 night-time noise criteria, it will comply at all other times.
