The Sewer Sentry System dramatically reduces rainwater inflow and corrosive gasses
Inflow reduction technology, US Patent 8,851,781 B1
Our Sanitary Sewer Overflow Solution
The Sewer Sentry is a device for manhole covers that dramatically reduces inflow during rainstorms, allowing water to flow through storm drains where it belongs. Its patented design also provides the ventilation needed to prevent the buildup of corrosive gases.
With Your Sewer Collection Systems
Inflow during rainstorms adds significant cost to wastewater processing. It also may create SSOs (sanitary sewer overflows), leading to possible fines or flooding of homes.
Sewer systems need to “breathe,” both in and out. When not enough oxygen reaches the sewer, hydrogen sulfide forms. That’s the gas that smells like rotten eggs. Customers complain.
The Sanitary Sewer Overflow Solution
Solves Both Problems Simply & Economically
The Sewer Sentry device stops storm water from going through hole in the manhole cover simply by creating a new point of entry ―a “raised hole”―that is 5/8” higher than the surface of the manhole. At the same time, it reduces sewer gas problems, by allowing enough oxygen to reach the sewer.
