Civil Engineered Chambers

Product Overview:

Pipex Thermoplastic Civil Engineered chambers are designed by us to suit your project specific requirements. Whether it’s a Combined Sewer Overflow (CSO), Flow Splitter Chamber, or Distribution style chamber, we can produce a model to suit your hydraulic designed chamber. Chambers can be supplied with factory fitted rebar, designed by our engineers, to suit the specific ground conditions.

We will liaise with your allocated third party equipment specialists and co-ordinate the installation of screens, pumps, and valves at our manufacturing facility.

The result will be a complete, off-site built engineered chamber delivered to your project site fully prepared for fast track installation

Ideally suited for urban areas, or remote locations, where traditional build methods involve traffic management issues and risk to operatives working for long periods in open excavations. Watch how we installed a 29.5 tonne chamber, complete with rebar, shuttering and internal equipment in just one day here.

All internal equipment such and valves and screens can be installed at our manufacturing facility. Each chamber is modelled in 3D to provide a working visual environment.
