Sediment Trap
Typically constructed on site using low cost vertical corrugated metal (CMP) and trash rack placed in stormwater flow path to capture sediment, debris, coarse particles and associated pollutants in a deep (>5ft) sump. Minimal to no volume loss occurs due to vertical accumulation of road side particulates and relatively small footprint. Typically located on road shoulder stormwater flow paths. Small sized Treatment BMP type constructed in Lake Tahoe.
