Water & Sewer Division

Annual Water Main Flushing Program

Starting Tuesday, April 18, 2017 the Water Department will begin its annual water main flushing and valve exercising program. The flushing program will be conducted on Monday through Friday from 8:00 P.M. until 12:00 A.M. The program will take approximately 8 weeks to complete. Flushing the water mains removes sediments in the pipe line, resulting in improved water quality. This work may temporarily cause discolored water but should become clear after running your cold water for a few minutes. The water will remain safe to drink during this program.

If you have any questions or problems with your water, please call the DPW – Water Division Office at (978) 658-4711. We wish to thank you in advance for your patience in this endeavor.

The Town of Wilmington's Water & Sewer Division is responsible for overseeing and operating both water and sewer infrastructure. The water distribution system consists of approximately 138 miles of water main, four groundwater wells, multiple pumping stations, two water treatment plants, three storage tanks and 1,242 public fire hydrants. The town also maintains interconnections with bordering towns and the MWRA. Serving approximately 99 percent of Wilmington residents, Wilmington's average water demand is about 2.2 Million Gallons per day. 

Originally established in the 1950s, the sewer system includes approximately 34 miles of main pipe, nine pump stations, 1,722 services and a septage receiving facility. Wastewater flow from Wilmington is carried to the Massachusetts Water Resource Authority (MWRA)'s sewer system and ultimately reaches the MWRA Deer Island Treatment Facility.
