The Upper Ely Interceptor Sewer System was part of the City’s Northern Area Master Plan. The intent of the system was to foster development and increase sewer capacity to provide a higher level of sewer service to the area. Phase IV extended the existing interceptor by approximately 7,400 feet of 30” sanitary sewer.
Unique features impacting 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 route was through a well-established neighborhood, as such, public outreach and coordination was an important component of the project.
The termination point was set to allow for future connection and development growth, as well as a future Phase V of the interceptor. The design accommodated a mixture of open-cut gravity installation and trenchless installation technology.
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.
