The Water and Sewer Department is a municipally owned utility for the residents of Shrewsbury. Our water supply is derived from a series of gravel packed wells pumping over 4 million gallons of water a day. The Sewer Department was started as a separate department in 1963. Wastewater is treated with primary and secondary treatment at the regional Westborough Plant.
After treatment water is discharged into the Assabet River. The Water Department supplies over 11,000 service connections through over 200 miles of water main to approximately 33,000 people. The Sewer Department operates and maintains approximately 40 pump stations for over 165 miles of sewer main.
