Stormwater Pollution Prevention
The City of Norwood Payneham & St Peters is committed to reducing the detrimental impact stormwater pollution can have on our natural waterways.
In 2019, the Council began a project that will see the City’s stormwater drainage infrastructure upgraded over a 15-year period.
The $38.4 million upgrade will address and reduce the impacts of flooding and reduce stormwater water run-off, helping to protect residents, their homes and property, as well as the City’s assets such as footpaths, kerbing and street trees.

Stormwater and stormwater pollution
Stormwater is water which collects on areas such as footpaths, roads, gutters and other surfaces after heavy rain. As rain falls on and runs off mostly non-porous surfaces, it can accumulate pollutants, rubbish or fine matter on the surface, such as, oil, grease, heavy metals, nutrients, sediment, organic matter and litter. When stormwater is contaminated by these pollutants, our natural waterways also become polluted.
Stormwater pollution causes problems for our waterways, such as fish deaths, loss of native vegetation and algal blooms, all of which degrade the water quality in the waterway.
Most of the stormwater drains in the Council area flow to either First, Second or Third Creeks, which flow into the River Torrens, which then flows to Gulf St Vincent.
There is no treatment of stormwater entering our gutters; therefore only clean rain runoff is legally allowed to enter the stormwater system.
Under the Environment Protection (Water Quality) Policy 2015, every person, business, industry and government agency has an obligation to protect water quality and prevent stormwater pollution.
