East Grove Street Water Treatment Plant

Weston & Sampson was selected to perform a full-scale design to replace the existing East Grove Water Treatment Plant (WTP) existing facility in Middleborough, Massachusetts.

Our team performed a preliminary evaluation at the existing facility in 2022, concluding it was at its end-of-useful life, and found the well source exceeded PFAS6 regulations. We then recommended the design and construction a new 500-gpm WTP to treat iron, manganese, and PFAS. The new WTP is a 9,500-SF masonry building that includes a process floor area for iron, manganese, and PFAS treatment, administrative spaces for DPW staff, two offices, a laboratory, breakroom and restrooms/locker rooms. The design included rehabilitation of the original historical 1980 pump house and the 4,500-SF pre-engineered metal vehicle storage facility. Design features include mitigation of floodplain impacts, historical restoration, archaeological investigations, hazardous building materials inspection, and MassDOT permitting. Construction is funded through the State Revolving Fund (SRF).
