The Hultman Aqueduct had been supplying most of Metro Boston drinking water since 1939. The 13.4 mile aqueduct runs from the Carroll WTP in Marlborough to Weston. In 2003 a duplicate water supply tunnel was completed so much need repairs could be made to this aging infrastructure.
This Aqueduct with its 46 culverts and numerous valves and connections needed an expert industrial coating contractor that could provide the proper corrosion protection for years to come; The John W. Egan Company. 70 Years of Safety and Excellence.
