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, eleven pump stations, over 1,700 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.
