Sedimentation

Sedimentation is a process that removes pollutants in water through gravity settling. Sedimentation systems reduce the flow rate of the water, allowing particles to settle to the bottom or float to the surface. A well-functioning system will let fine particles clump together and then settle.

Sedimentation occurs in:

• Sedimentation basins
• Tanks
• Ponds and lakes
• Wetlands

Sedimentation can be used as a stand-alone treatment for water or as part of a larger treatment system.

The Fitzroy Gardens Stormwater Harvesting System uses sedimentation as part of the treatment process.
