Current and Upcoming CRR Projects

Projects scheduled for Construction in 2024/2025

Pecan Close, Cherrybrook Gross Pollutant Trap (GPT)

  • A gross pollutant trap (GPT) is planned for construction at Pecan Close to improve the performance of the existing biofilter.
  • The GPT is expected to annually remove around 17 tonnes of pollutants captured from the surrounding 17-hectare catchment area.
  • It will be an underground vortex style GPT.
  • The addition of this GPT will allow the bio-basin to better remove the dissolved pollutants in the stormwater.

Derribong Place, Thornleigh Gross Pollutant Trap

  • A gross pollutant trap (GPT) has been designed for Derribong Place. This device will complement the other gross pollutant traps within Larool Creek catchment.
  • The GPT is expected to annually remove around 100 tonnes of pollutants captured from the surrounding 130-hectare catchment area.
  • It will be an underground vortex style GPT.

Edward Bennett Treatment Train

  • A GPT, bio-basin and stormwater harvesting device is planned for construction at Edward Bennett Oval, Cherrybrook.
  • This treatment train will clean the stormwater and make it viable for use in the sports field irrigation of Edward Bennett Oval.
  • Around 50,000 litres of storage for treated stormwater will be built.
  • The infrastructure will be built into the landscape and will become a feature of Edward Bennett Oval.

Projects Planned for Design in 2024/2025

All designs will be advertised for public consultation.

The Lakes of Cherrybrook

  • The Lakes of Cherrybrook will have 2 GPT’s designed during the 2024/25 financial year, one for each inlet.
  • They will both be underground vortex style GPT’s. Together they are forecast to capture up to 32 tonnes of pollution each year.
  • The goal will be to improve the amenity of the Lakes of Cherrybrook.

Wetland investigations and design

  • Council will undertake investigations and design at 3 wetland locations.
  • The designs will improve the performance of the wetlands for pollution capture, habitat values, urban cooling and amenity.
  • If the investigations are favourable, Council will proceed to detailed design.
  • Possible locations include Lakes of Cherrybrook, Clarinda Wetlands and Walumeda Wetlands.
