Pre-Sedimentation Not all systems use pre-sedimentation, but pre-sedimentation is often used when raw water turbidity is high or highly variable. Pre-sedimentation basins range in size, depending on the flow, and the water is sometimes pre-treated with a coagulant and/or a polymer prior to entering the pre-sedimentation basin (AWWA, 1999).

Horizontal flow tanks. The simplest form of sedimentation is to fill a jar or tank with water, leave alone for a long enough time for particles to settle and then decant off the resulting water without the sediment. In practice this is rarely viable in treating water for townships, and therefore sedimentation tanks are operated continuously.
