The benefits of action on sediment control

Together with builders, residents, Local Government and environmental managers, the Sediment Task Force is working to control sediment to:
  • Protect hydrological functions of rivers, wetlands and other water ways
  • Reduce the risk of flooding houses and roads as a result of blocked stormwater drains
  • Prevent sediment from smothering the reeds, plants and seagrasses that keep our rivers, wetlands and oceans healthy
  • Protect aquatic invertebrates and benthic algae populations, whose presence is necessary for waterways to remain healthy ecosystems
  • Prevent fish, prawns, crabs and other aquatic wildlife being killed due to the detrimental effects of sediments entering ecosystems
  • Prevent sediment from covering grass in the parks that receive stormwater runoff
  • Reduce nutrient enrichment of waterways and associated algal blooms
  • Prevent the creation of breeding grounds for pest and potential disease causing mosquitoes and midges and protect public health from mosquito-borne diseases and pathogens
  • Help to maintain stormwater management systems such as biofilters, pervious paving, infiltration cells and tree pits that are critical to protecting our rivers, wetlands, marshlands and oceans
  • Reduce the risks of accidents on roads and paths.
Success in sediment control will:
  • Reduce the costs to governments and the community for stormwater and river and wetland management
  • Protect wetland hydrological and biological functions and water quality values
  • Protect our local parks (where storm water is often discharged)
  • Protect the aesthetic value of rivers, wetlands, marshlands and oceans that are icons of the natural beauty of Perth and regional WA
  • Reduce sand and sediment build up on roads
  • Reduce the costs of supplying sand for building sites and fill for urban development.
