Understand the impacts of stormwater and sediment run-off from construction sites and how you'll need to control this.
As a builder or developer it’s important to understand the environmental and infrastructure impacts of stormwater and sediment run-off from construction sites and your responsibility to prevent it through suitable controls and measures.
Stormwater, sediment and erosion control should be implemented when development involves:
If suitable controls and measures aren’t put into place, polluted sediment such as mud, sand and soil can enter our stormwater drainage system, impacting our waterways including the Murray river and other local creeks, streams and habitats.
Sediment run-off can also block our stormwater drainage system increasing the risk of localised flooding.
As a builder or developer on a construction site, it’s important to familiarise yourself with the following policies and guidelines to help you understand, plan and meet your obligations for stormwater, sediment and erosion control.
For single lot developments, we typically require a drainage plan and sediment control plan to be submitted with your Development Application.
Large scale developments that involve extensive earthworks over a large area, such as a subdivision, typically require the following to be submitted with your development application:
Generally we also require onsite stormwater detention, such as a sediment basin, to form part of the design. Soil and erosion control conditions placed on your development consent will vary depending on the type and scale of your development and site specific circumstances.
Developers and builders are responsible for connecting a subdivision’s stormwater and drainage system to a legal point of discharge. This is to reduce the impact on neighbouring properties by managing stormwater on the premises and directing it into our stormwater drainage system.
You’ll find the technical requirements for stormwater management as follows:
It is an offence to allow any substance other than rainwater to enter our stormwater drainage system. If pollution occurs, notify us immediately on 02 6023 8111.
This allows for appropriate steps to be taken to minimise any harm to the environment and impacts on our stormwater drainage system.
