New England, being one of the first parts of the United States settled, has some of the oldest infrastructure. This is no different for the Town of Hull, Massachusetts. Recently, the Town put out a multimillion-dollar sewer rehabilitation bid for cured-in-place pipe (CIPP), which also included extensive manhole and structure rehabilitation. This sanitary sewer infrastructure was only 45 years old and is certainly not as old as other sewer systems in New England. Hull is a coastal community with high brackish groundwater and minimal pipe grades, so hydrogen sulfide has been an issue in the collection system, which has increased the rate of deterioration of the system. The image below provides an idea of just how flat the grades are in the area of the rehabilitation project and the amount of brackish ground water in the area.
