Silt Chambers

Purpose-built high density polyethylene (HDPE) pre-fabricated catchpit chambers are ideal for stormwater drainage systems. WASP Catchpit chambers are designed to separate silt and other particles, helping to improve the quality of water before it is reintroduced into the environment. They can be integrated into any drainage system requiring ‘in line’ silt and debris separation prior to attenuation or infiltration.
