Sediment Trap
also called: sed trap
Small excavated basin sized to hold sediment-laden runoff long enough for soil particles to settle out.
A sediment trap is a temporary basin, usually at a low point on a construction site, sized to capture concentrated runoff and hold it long enough for the suspended sediment to fall out. The cleaner water then overflows out through a spillway or outlet pipe.
Used where flow is too concentrated for silt fence to handle, at storm drain inlets, at the outlet of a stormed-out channel, at the toe of a long graded slope. Required as a SWPPP element on most regulated construction sites.
Maintenance is required: sediment that falls out has to be excavated and removed periodically or the trap fills up and starts passing the very sediment it was supposed to catch.
