Excess water seeps in, reducing pipe capacity, forcing unnecessary water treatment and, in some cases, causing overflows.
Because traditional manholes are often the first segment in a collection system to fail, Hamilton Kent has engineered The Lifespan System to eliminate the inflow of extraneous water into the sanitary sewer.
Not only is it an easy-to-install, integrated system, but Lifespan also seals all critical points: manhole structure to risers, risers to frame, and frame to cover. Lifespan provides a watertight, naturally corrosion-proof, and highly durable frame and cover system that delivers a longer service life.
Hamilton Kent also provides a number of pipe and manhole gaskets and flexible pipe-to-manhole connectors that would assist in sealing sanitary sewer systems if major replacement or relining of pipe and/or structures is required.
