The Sewer Sentry System Reduces Sanitary Sewer Overflow Problems By

Dramatically Reducing Inflow During Rainstorms

AND

Reducing Exposure To Corrosive Gasses

Sewer Sentry Overflow

THE PROBLEM

With Your Sewer Collection Systems

YOUR FIRST ENEMY

INFLOW DURING RAINSTORMS

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.

YOUR SECOND ENEMY

SEWER GASES

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

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.

Standard

MANHOLE

With a standard manhole, heavy rain inflow leads to more water in the storm drain and sewer that needs to be processed thus overwhelming the pumps.

MANHOLE

With the Sewer Sentry manhole, the rain water is correctly diverted to the storm drain, allowing the system to breathe properly and not overwhelming the pumps.
