In 2003, the city of Newburyport Sewer Department completed a sewer rehabilitation program within four subareas identified as having the highest infiltration rates throughout the system. This represented an important milestone for the city in its ongoing efforts to reduce infiltration/ inflow (I/I) quantities and improve system operation following a holistic approach. This holistic approach included consideration of both I/I reduction and structural integrity issues in developing a recommended program for sewer rehabilitation. The program consisted of a detailed investigation of all the sewer manholes and pipelines followed by rehabilitation utilizing both traditional (dig and replacement) and trenchless technology methods of construction. By completing this work, the city hoped to provide additional capacity in the system to accommodate sanitary flow from approximately 1,200 households located on Plum Island where a major water and sewer extension project is proposed. This paper presents the results of the I/I investigation and sewer rehabilitation program conducted within the city of Newburyport following a holistic approach.
