Inspection Chambers and Catch Pits

Our high-strength inspection chambers and catchpits have been developed to support efficient surface water management systems, providing reliable above-ground access for inspection and maintenance.

The range includes a variety of access chambers suitable for a wide range of applications while remaining fully compatible with the complete MetroDrain pipe, fitting and accessory portfolio. The MetroDrain inspection chamber and catchpit range has been specifically engineered to accept 150 mm MetroDrain and N-Drain systems at all inlet connections, as well as at the outlet.

Installation is simplified through the use of EASY FIT SEAL technology, which enables rapid connection of pipes and accessories while ensuring a secure, watertight interface with the chamber base.
