Proposed upgrades to the town’s aging wastewater treatment plant are projected to cost about $86 million. The first phase, estimated to cost $55.7 million, will address the state-mandated phosphorus limits, according to a presentation given to the Public Utilities Commission this week by AECOM, a firm hired to design the project. The second phase, estimated to cost $30.8 million, will upgrade other equipment and processes, including nitrogen removal.
