Sewer Collection System
The town's collection system consists of approximately 130 miles of gravity sewer pipe ranging in diameter from six to 30 inches. The town does not operate any wastewater treatment facilities. Sewage from Needham is conveyed to the MWRA interceptor system which flows to the MWRA Treatment Facility located at Deer Island by 10 municipally owned and operated wastewater pump stations. Flow from Needham is collected by the MWRA Wellesley Extension interceptor system that services Needham, Wellesley and Dedham in addition to the Framingham Extension Sewer. The MWRA currently has two continuous recording flow meters that record Needham's total wastewater flow.

The town's collection system conveys an average daily wastewater flow of 4.25 million gallons per day.
