Although it is an everyday occurrence, it can be costly for municipalities when lift
station check valves fail and leak sewage back into the wet well from force mains.
Pump wear, as well as the operational expense of inspecting, cleaning, repairing
and maintaining check valves, is well documented. Also understood is the expense
of force main sewage backflow into the wet well having to be pumped multiple times.
This paper is a brief discussion of the techniques and use of Inline Duck Bill All
Elastomeric Check Valves to prevent force main sewage backflow.
