Inflow Protectors without Odor Control

During rainy weather, an average manhole allows slugloads from 4,000 to 12,000 gallons per day of rain water,to enter the treatment system.

PEC Manhole Inserts eliminate this problem, while built-in pressure relief valves allow the manhole to "breathe." Units are made to exact size from virtually indestructible material and can be supplied with odor control media when required. Simple to install, long lasting product that eliminates in-flow of rain water into the sanitary sewer system. Added advantages are the elimination of debris and dirt, reduced or eliminated manhole odors, and no more manhole cover rattle noise.
