The Sewer Sentry Solution


Traditional manhole covers are a weak link in our fight against sewer overflow, leaking as much as 7,200 gallons of water in a single day. 

Heavy rain inflow leads to more water in the storm drain and sewer that needs to be processed thus overwhelming the pumps.

Sewer Sentry is a game-changer – with our technology, leakage is drastically reduced to approximately 110 gallons per day*, ensuring efficiency and sustainability.

That's a 98% reduction in inflow!

* Tested and verified by the Trenchless Technology Center (TTC) at Louisiana Tech University in April 2024.



With the Sewer Sentry installed on a cast iron or composite manhole, the amount of leakage reduces drastically.

A sobering insight from the Neenah Foundry Company reveals the stark inefficiency of standard management practices: A single inch-hole in a 24” manhole cover during a rainstorm can admit an astonishing 13.23 gallons of water per minute

For a town with 400 manholes, that’s an excess of 843,360 gallons due to a four-hour storm

The Sewer Sentry slashes this number to less than 85,000 gallons. The savings for your municipality? Enormous, in both finances and resources.
