Work Performed
The project included the installation of 3,304 LF of 48” and 60” FRP sanitary sewer that served as two of the three primary sanitary sewer interceptor lines for the City of Billings. Along with the interceptor installation, the project also included concrete-encased FRP Tee installation that acted as access manways or sanitary sewer manholes and abandonment in place of existing interceptor lines with flow fill. Two major bypass setups were successfully completed during highwater season for connections to the existing system. Bypass flows exceeded 19 MGD and required 24-hour monitoring due to the close proximity of the Yellowstone River. WMCI was able to assist the City of Billings through the Value Engineering process that resulted in additional fill onsite being placed over the entire project area of approximately nine acres in order to achieve necessary buoyancy requirements for the Interceptor line. Over 35,000 CY of material was placed over the entire area which allowed for originally designed concrete cradles over the Interceptor to be removed. Yellowstone County and the City of Billings both benefitted from the grading performed and turned what was once a desolate area into now a fully functioning parking / camping / storage area for MetraPark.
