Xylem's Godwin Pumps Tackle Large Bypass System In Greenwich, Connecticut


Eight-week bypass schedule allows for completion of major infrastructure upgrades

The town of Greenwich, Connecticut’s existing 54-in. diameter concrete sanitary sewer line, which carried nearly all of the town’s wastewater flow, was being attacked by hydrogen sulfide and deteriorating. After a condition assessment, it was determined that this critical infrastructure should be rehabilitated as soon as possible. In order to complete the sanitary sewer rehabilitation while maintaining treatment operations, a 40.9 million gallons-per-day temporary bypass system was needed to divert the fl ow from three areas of town to the wastewater treatment plant.

Along with the town’s consulting engineer, CDM Smith, Richard Feminella, P.E., Wastewater Division Manager for the Greenwich Department of Public Works, reached out to Andy Culver, Outside Sales Representative for Xylem, for a pump rental solution. Culver and the Xylem team had worked with the town of Greenwich in 2011 on a bypass system at the wastewater treatment plant. Feminella selected Godwin pumps for this large bypass job, based on the town’s previous experience with the company. “They certainly have the ability and the experience, and they’re very responsive,” Feminella said. “In our own experience, Godwin has the most reliable pumping system.”
