Water Authority plans new treatment plant to boost distribution and tackle PFAS issues

The Middleborough Select Board and Water & Sewer Commissioners convened on January 29, 2025, to discuss critical updates regarding the town's water supply and infrastructure improvements. The meeting focused on the challenges and plans for developing new water sources, particularly in light of regulatory hurdles and the need for enhanced treatment facilities.

The discussion began with an acknowledgment of the difficulties in obtaining new water sources, with permitting processes expected to take over a year. The board highlighted plans for supplemental wells, similar to those established at East Main, which would provide clean water and address issues related to iron and PFAS removal. A well that has been offline for over a decade is anticipated to come back online if the new treatment plant is constructed, alongside two additional supplemental wells.

The proposed site for these developments spans 18 acres at the Miller well location, which has already undergone a survey. The board expressed optimism about the permitting process, noting that it would be less complicated than previous projects due to the absence of wetlands and archaeological concerns.

Logistical challenges were also discussed, particularly regarding the infrastructure needed to connect the new water sources to the existing distribution system. The board noted the proximity of the new wells to major highways, which could facilitate drilling operations. However, they acknowledged potential complications with hydraulic pressure as they plan to consolidate water flow from multiple sources into a single distribution point.

The board emphasized the importance of addressing hydraulic modeling to ensure the distribution system can handle the increased pressure from the combined water flow. They are working with consultants to evaluate the necessary improvements, which may include upgrading water mains to accommodate the new system.

In conclusion, the meeting underscored the town's commitment to enhancing its water supply infrastructure while navigating regulatory challenges. The board plans to continue discussions on hydraulic modeling and distribution improvements in future meetings, aiming to ensure a reliable and safe water supply for Middleborough residents.
