摘要

The Town of Norwood, Mass., is similar to many communities across the United States in that it is under an EPA consent decree to reduce water pollution and inflow and infiltration (I&I). Norwood is a suburban community located south of Boston, with a population of 28,000. The Town sewerage network is comprised of 100 miles of pipe ranging in size from 4 to 24 in. The Town embarked on a program of work to meet EPA compliance by 2023.To assist with the design and implementation of this program Norwood retained CDM Smith Inc. as the consulting engineer. CDM Smith Inc. is an international engineering firm based in Cambridge, Mass., with regional offices across the United States. CDM has worked with many communities under an EPA consent decree bringing a more progressive approach at eliminating infiltration of an aging sewer system. The integration of lateral lining into a comprehensive rehabilitation approach is a new and effective solution to the problem. Lateral lining is the final rehabilitation step, which yields the most cost-effective use of public expenditures in permanently sealing your sanitary sewer collection system by reducing and eliminating infiltration and eliminating exfiltration, as well.
