Stormwater and sediment control

Details

Last Updated: Wednesday, 17 November 2021 08:50

Some of the effects of rainfall from storms and stormwater carrying sediment are:

• an increase in amount and speed of water – affecting hydrology, erosion and flooding.
• the change in quality of water – potential pollutant export and movement and deposition of sediments.

In large amounts, these substances can affect waterways as either potable water supplies or aquatic ecosystems.

Urban, commercial and industrial areas have extensive areas of waterproof surfaces such as roofs, roads, driveways, car parks and paving which create stormwater runoff. As a result of steadily increasing water-repellent surface areas, increasing runoff is a pressure on creek areas. Soil at building sites can also be washed onto roads which may flow into creek areas.

You can access information below on how to control and minimise erosion impacts from building sites.
