Use of inventory to make efficiency savings in gully

cleansing

Scrutiny recommendations Current geographical

approach to gully cleansing is continued.

Collection of gully information to be included in any such contracts.

Contracted out gully-cleansing should be done through one contract which will cover more than one District area.

A more intelligence-led approach to gully cleansing should be adopted along with some record updating information on gullies being cleansed.

A contract and tendering process should be developed to include all of the gully-related work currently undertaken by Districts on our behalf.

Policy seeks to ensure that all gullies are cleansed at least once a year. It is acknowledged that arrangements are in place to permit greater local flexibility to meet local needs.


Intelligent gully cleansing project aims• To capture intelligent data relating to cyclic gully

cleansing operations.• Provide and develop in cab technology to operatives

with mapping in GIS format.• Show known gully positions on in cab mapping,

allowing data to be edited, relocated, created or deleted.

• Time and date stamping of site operations so as to provide better management information;• customer complaints/queries.

• Reduce/remove the requirement for paper based processes.

• Look to promote efficiency, better informed service delivery and cost savings.

How does intelligent data capture help drive - efficiencies

Less administration of paper records Simple reporting Map / Table / Spread sheet’s

Less need for manual data input Quantified problem/Defects/Jobs

Budget efficencies and savings identification Improved management of gully cleansing

Help drive consistent level of service


Where do we want to go and how can we get there?

• Streamline the service

– Reduce some cleansing– Increase others– Weather related cleansing – refer to flood risk register– Consistent level of service

• Looking for

– Efficiencies– Cost savings– Better data management– Reduce flood risk– Improve asset register - gullies and linear drainage


Using data to support changes in level of service

• Road classification (must be minor estate road).• Low speeds (<30mph)• Must not be a tree lined street.• Must not have an historic report of flooding. • Must not be a street which interacts with DCC

surface water flood maps (predictive)• >70% of the recorded information must state

that the gullies are reported as 0-10% arising's.• If >30% of the gullies have been reported as

needing a dig out then the street stays in.• Must not have any blockage defects.


Using data to support changes in level of service

• Road classification (must be minor estate road).• Low speeds (<30mph)• Allow for some trees on the street.• Must not have an historic report of flooding. • Must not be a street which interacts with DCC

surface water flood maps (predictive)• >70% of the recorded information must state

that the gullies are reported as 0-10% arising's.• If >30% of the gullies have been reported as

needing a dig out then the street stays in.• Allow 15% blockage defects.
