Xylem's Bypass Enables Critical Upgrades For Aging Sewer Lines In Greenwich, Connecticut

To help upgrade a historic town’s infrastructure, local Xylem team designs a comprehensive temporary bypass that employs a successful CIPP solution

Greenwich, Connecticut, located in the tristate area immediately surrounding New York City, is a scenic New England town that is home to approximately 60,000 people.

It was first settled in 1640 on a spot between the Asamuck and Patomuck Rivers, and like many historic towns, Greenwich proactively addresses aging infrastructure on a continuing basis. Its ongoing initiatives include repairs and upgrades to the town’s wastewater treatment plant and 28 pumping stations.

“Some components of our sanitary sewer and wastewater system are well beyond their expected useful life,” says Richard Feminella, Wastewater Division Manager for the Town of Greenwich, “so each year we budget for ongoing repair, replacement or upgrade projects.”

The Sewer Division of the Greenwich Department of Public Works planned to upgrade critical sewer line at multiple sewer manholes along Bruce Park Avenue, a busy roadway parallel to Interstate 95 in downtown Greenwich. Given the proximity to the town center and substantial traffic volume, the project was high-visibility and high-profile.
