The Watertight Manhole System provides a quicker, safer, high quality precast concrete manhole system with a main tapered channel in the base to eliminate cascade.
The Stanton Bonna Watertight Manhole System is a precast off-site solution which enables contractors to install a modular water tight manhole without the need for a concrete surround.
Made here in Derbyshire, this quick assembly system comprises of a monolithic precast concrete base pre-benched to any inlet / outlet configuration, together with thick walled chamber rings with water tight joints incorporating an elastomeric gasket and a sealed cover slab. The unique design includes a main tapered channel which eliminates any cascading between main inlet and outlet pipe – where the main inlet pipe is a smaller diameter to the main outlet pipe. The system also incorporates push fit elastometric seals for inlet and outlet pipes.
Specifiers, designers and contractors can be assured that the Stanton Bonna Watertight Manhole System offers a safer, faster, sustainable, off-site bespoke manhole solution.
