Sediment traps and basins should be constructed prior to disturbance of upslope areas, if possible, and continue functioning until the contributing drainage area is fully stabilized. These structures are typically placed near the perimeter of the site, where flows concentrate in swales, ditches, or other low areas. They represent one of the most effective and reliable measures for treating sediment-laden runoff from construction sites. Sediment traps and basins are very similar in their siting, sizing, and design, with sediment traps serving areas of five acres or less and basins handling larger areas. Sediment basins typically serve larger areas than sediment traps and may feature earthen embankments that retain runoff for longer periods of time, releasing runoff via floating, perforated, or slotted risers or floating skimmers that draw clarified water from the surface Sediment traps may serve several small catchments on a site, retaining runoff using embankments and other barriers and discharging through an armored overflow or piped outlet to a vegetated swale or other drainage feature. Sediment traps and basins function by intercepting and detaining site runoff, which allows soil particles to settle out prior to discharge.

Sediment traps and basins are very useful on construction sites with moderate to steep slopes. Temporary sediment basins can be converted to permanent stormwater management basins after construction is complete. Sediment traps are often temporary and usually decommissioned after the disturbed area is stabilized (i.e., with vegetation or other cover). Proper use of these structures can greatly reduce sediment transport off-site if properly designed, installed, and maintained, sediment removal efficiency of 80 percent or greater can be achieved, depending on soil particle size. They may be constructed as smaller sediment traps – serving disturbed areas of less than five acres – or as larger sediment basins, handling mass grading runoff from subdivisions, commercial/institutional sites, or roadway projects. Sediment traps and basins are settling ponds formed by excavation and/or an embankment that intercept and retain sediment-laden runoff from a construction site for a sufficient period of time to allow the majority of sediment to settle out prior to being released from the site.
