Our City is lucky to have the beautiful Nepean River and many creeks. Council and our community care about the health of these waterways.
Ways we work for healthy waterways include:
Stormwater is rainwater that doesn't soak into the ground but flows from roofs, driveways, gutters and roads into the stormwater system. Urban environments generate a lot of stormwater because of all the hard surfaces.
Stormwater runs into our creeks and rivers. Unlike sewage, it isn't treated before it goes into the waterways.
Any litter, garden waste, oil or other chemicals that the water collects on hard surfaces like roads and in the gutters will end up in the waterways we use for swimming, fishing and recreation.
Council is responsible for stormwater management, which involves transporting this rainwater from urbanised areas to the natural waterways. We build and maintain pathways and gutters.
We install and empty Gross Pollutant Traps (GPTs) to reduce the amount of litter that gets into the stormwater system.
Please help keep pollutants out of our stormwater, to improve the quality of our waterways.
Water Sensitive Urban Design Policy (PDF 240KB) was adopted in December 2013. The policy includes controls to reduce the impact of urban development on the health of the Nepean River and local waterways. The policy also links to our
City Strategy 2013, builds on previous Stormwater Management Plans and complements Council's work with our community to protect our environment now and for the future.
WSUD is the sustainable management of water in urban areas through intelligent and integrated design. It considers all aspects of the urban water cycle including potable (drinking quality) water, rainwater, wastewater, stormwater and groundwater.
Key principles include:
The policy introduces a framework for industrial, residential and commercial developments to improve stormwater quality and reduce potable water consumption to help restore the natural water cycle. It details catchment management and water quality controls which depend on a
development's scale and type. Performance criteria outlined for stormwater conservation, quality and quantity would apply to developments including:
The policy evaluates total gross pollutants, total suspended solids (TSS), Nitrogen (TN) and Phosphorus (TP) and includes a flow management target to reduce erosion within creeks. A WSUD Strategy would also be required under the policy including stormwater modelling
to demonstrate how targets can be met.
Water Sensitive Urban Design Technical Guidelines (pdf 1MB) and
Addendum 1: Deemed to Comply Toolkit for Residential, Industrial & Commercial Developments (pdf 5MB) which help industry comply with the Policy. They will be regularly reviewed and updated to reflect changes within the industry and best practice.
