Lewiston, New York, USA - Wapro Access with WaStop DN110

City of Lewiston| Lewiston, New York, USA| Flood protection

The problem

A section of Upper Mountain Road in Lewiston, New York was repeatedly experiencing basement floodings. This was the result of having a combined wastewater and stormwater sewer in an area prone to flooding from the Niagara River. Jeffery Ritter from the city of Lewiston met with Bob Wiltshire from Koester Associates, and they discussed the benefits of installing WaStop inline elastomeric check valves in order to prevent backflows and flooding. Jeff suspected that the WaStop might be just what Lewiston needed.

Solution

WaStop^® Inline Check valve

In 2013, a packaged residential WaStop unit was installed in a private home in an area where previous floods had caused more than $4,000 of damage to basements each time flooding occurred. Since the Wapro Access unit was installed, there have been no more flooded basements.

Design: Wapro Access Chamber with a WaStop module. Note the 8' extension tube installed as a riser from the Wapro Access Chamber.
