On June 14, the Brunswick Sewer District held an open house at their wastewater treatment facility to celebrate the completion of a multi-year plant upgrade. PC Construction broke ground on the $20 million construction management-at-risk project in May of 2015 with the construction of the collections maintenance facility.
The upgrades to the facility, which was originally constructed in 1966, replaced equipment and systems at the end of their useful lives and improved plant efficiency. As a result, Brunswick Sewer District will realize a reduction in long-term operating costs.
Work included the construction of two new maintenance facility buildings for the Collections and Maintenance group and a new headworks building with influent screen, washpress, and septage receiving system. Modifications and upgrades improved the influent junction structure, sludge dewatering system, trickling filters, secondary clarifiers, disinfection system, sludge holding tanks, odor control system and primary effluent pumping system, as well as structural, architectural, mechanical, electrical, SCADA and instrumentation systems. An extensive preconstruction process ensured only limited and planned impacts to plant operations.
This project marks the first treatment plant project in the State of Maine funded by the DEP State Revolving Fund to utilize the construction management at-risk delivery method.
