Sediment and erosion control

Managing sediment runoff from a construction site

Sediment generated from soil erosion on building and construction sites can be a major source of pollution to local waterways. In fact, a single building block can lose four truckloads of soil in one storm. Any sediment that moves off-site typically enters stormwater drains, clogging the stormwater system and transporting attached pollutants including oils, heavy metals and hydrocarbons into local waterways. Excessive sediment can kill fish and aquatic plants, silt up streams, and block stormwater pipes, which can lead to increased flooding.

The building and construction industry is responsible for soil and water management throughout all phases of a development. The soil and water management guidelines discussed in the Fact Sheets minimise erosion and sediment run-off from building sites. Benefits include:

  • Greater compliance with the appropriate regulations including state environmental laws, thereby reducing the risk of fines and other penalties.
  • Improved wet weather working conditions, reduced downtime and earlier building completion.
  • Fewer public complaints and a better public image for businesses.
  • Reduced stockpile losses and clean up costs.
  • Healthier waterways and a cleaner environment for everyone.
