The Water Treatment Facility, built in 2006, produces an average of 6 million gallons of drinking water each day. Water from the Merrimack River is pumped into the treatment facility to begin the treatment process. Treatment processes include: coagulation, flocculation, sedimentation, filtration, fluoridation, Ultraviolet (UV) disinfection, as well as chlorine disinfection. Finished water is pumped to the Ames Street Reservoir, the High Service Water Tower (Tower Hill Tank), the Mount Vernon Tanks, and the Prospect Hill Tank.

The City's Drinking Water Treatment Facility operates 24 hours a day, 7 days a week to provide the highest quality water to the residents of the City. The facility produces over 2 billion gallons of water each year. Water quality is continuously monitored by laboratory testing and online analysis to ensure our water meets and exceeds state and federal drinking water regulations at all times. The Water Treatment Facility also maintains several ancillary facilities to maintain adequate water pressure and volume throughout the City of Lawrence.
