Stormseal Manhole Inserts

In the United States, and much of the populated world, accommodating ever escalating demands on municipal water treatment and distribution
In the United States, and much of the populated world, accommodating ever escalating demands on municipal water treatment and distribution coupled with wastewater treatment and disposition while controlling capital, operating and maintenance costs is a Key Challenge confronting almost every community.

The added strain of rainwater (or other unanticipated sheet flow) influent, pouring into sanitary sewer systems, can quickly exceed the maximum capacity of sanitary sewer systems, lift stations, and treatment facilities, causing problems including regulatory violations, manhole overflows, spills, pick hole geysers, sewage backup into homes and offices, lid blow offs, and generally inefficient and costly water treatment and use practices.

A simple yet effective solution to control this problem is the installation of manhole inserts. The manhole insert acts to prevent flow into the manhole. By keeping the flow out of the manhole, sanitary sewer system integrity can be preserved.
