Weholite CSO Control Chambers are manufactured and assembled off-site and are designed to meet project-specific requirements using a standard set of components. This improves site productivity, reduces installation time and construction materials, and provides major savings on programme costs.

Having been prefabricated at the manufacturing plant in Newport, Chambers are delivered ready to install with any type of CSO control devices factory-fitted.

Weholite is unique in providing chamber systems in HDPE without any need for concrete inside or outside providing structural integrity.
