Spring and Summer 2023- 1100’ of mainline sanitary sewer was rerouted around the existing High School in order to abandon an existing line running through the property and freeing the space for a new addition. The entire run was installed at a depth of 20’, while facing a high water table and tight working areas. 2 “vault” manholes were cast in the field in order to accommodate the new 15” main, new 30” overflow line, and connect to the existing 33” main. It was a team effort by all trades and subcontractors to successfully complete this project on time.
