Engineered steel manholes are installed underground to provide access to control valves, piping systems, and other equipment that frequently require observation, inspection, cleaning, and maintenance.


PERMA-PIPE offers custom, watertight prefabricated steel manholes to reduce installation and life-cycle maintenance costs over traditional concrete manholes. They are fully assembled and tested with all valves and other equipment as required.
