Coleman Engineering was retained by Carlson, Barbee & Gibson who are providing engineering services to the Mount Diablo Resource Recovery Park in support of the expansion of their site in Pittsburg, CA. The expansion will add sewer loading to the existing system and Coleman Engineering evaluated alternatives and recommended a concept for improving conditions at the two existing sewer lift stations.
After a site review and subsequent calculations, a number of recommendations were made for the improvement of the sewer lift stations, including, the addition of float controls for more frequent cycling, additional pumps to provide redundancy in case of clogging or other non-performance issues, and the addition of a rail system to aid in the removal and servicing of the pumps.
