Silt and Contamination Prevention

Poor management of silt and silty water is a major cause of serious pollution incidents from construction sites. Silt for these purposes is a fine inert sediment derived from soil and rocks. Silt pollution can:

• damage and kill aquatic life by smothering and suffocating

• reduce water quality

• cause flooding by blocking culverts and channels Many construction processes produce silty water: movement and maintenance of plant and vehicles on site, rain water run-off from exposed ground, trenches or foundations and even from plant, wheel and boot wash facilities. If you can, prevent water becoming contaminated with silt in the first place, as this reduces the risk of pollution and the overall cost of your control measures.
