This project included development of alternatives and recommendations at the Town’s water supply site for upgrading the primary well piping, a critical river pipeline crossing, and repiping another well into the common treatment facility. The final design resulted in crossing the Mad River and required permitting from NHDES and USACE for impacts to the regulated shoreland and to the stream and its banks. Alternative designs were analyzed that were successful in mitigating impacts to this important resource.
