WASP Catchpit Chambers

catchpit chambers

WASP catchpits are designed to separate and retain silt and other particles from stormwater, helping to protect the downstream drainage system and local environment. WASP catchpits are bespoke, watertight, structured wall chambers, manufactured to suit project-specific requirements. Health and Safety benefits become apparent during handling and installation, due to their strong, lightweight construction and integral lifting points. In addition, off-site fabrication ensures uncompromised, high quality products being delivered to site ready-to-install, reducing installation time and costs.
