Merrimack River Water Main Crossing & New Raw Water Intake
The civil engineering profession plays a vital role in protecting public health and keeping communities vibrant. When PFAS contaminated wells were found at more than 360 homes in Litchfield, New Hampshire, Pennichuck Water Works (PWW), a local water utility, needed a fast-tracked solution. Tighe & Bond was already under contract with PWW to design and provide construction administration services for a new 30 MGD in-river raw water intake on the Merrimack River next to Litchfield. The firm was asked to shift priorities and began work with multiple stakeholders, subconsultants, and contractors on the design and construction of a new water main that would cross the Merrimack River and connect Litchfield to a safe public water supply.
