The Upper Ely Interceptor Sewer System is part of the City’s Northern Area Master Plan and is intended to foster development and increase sewer capacity to provide a higher level of sewer service to the area. Phase IV extends the existing interceptor by approximately 7,400 feet of 30” sanitary sewer with a termination point set to allow for future connection and development growth, as well as a future Phase V of the interceptor.
Shrewsberry provided complete engineering services on this project, including preliminary engineering for the routing study, design phase services, project management, construction administration assistance, and public outreach. The design accommodated a mixture of open-cut gravity installation and trenchless installation technology.
There were unique features which impacted the design and construction of this project included poor soils, such as marl; wetland coordination; utility coordination; lift station removal; and flow reduction to a second area lift station. The designed route went through a well-established neighborhood, therefore public outreach and coordination was an important component of the project.
