“The work is 90% done and we expect the project to be substantially finished by May,” Dave Capacchione, director of engineering and facilities, said on Thursday. “The project is within budget and we were able to do the work without any interruption in service.” The two-year refurbishment project at the 50-year-old main facility off Wauregan Road focused on operational upgrades, including demolition work; replacing original parts too outdated to meet state and federal guidelines for the removal of nitrogen and phosphorous; and adding new components, such as four new pumps, aimed at making the plant run more efficiently. In September 2014 — less than a month after a referendum on the issue failed — residents approved spending $25.8 million for work at the main plant with a state funding package earmarked to cover 20 percent — or $5.1 million — of the overall cost and the rest being paid through a 2 percent loan from the state Department of Energy and Environmental Protection’s Clean Water Fund. Massachusetts-based RH White Construction was awarded the contract for the main plant work with its bid of $18.1 million.
