The Town of Burlington’s goal is to produce the highest quality drinking water for all its customers.

To maintain our commitment to you, we routinely collect and test water samples every step of the way, from the source waters right to your home, checking for purity and identifying potential problems. A yearly Water Quality report is produced and sent to all residents in the town of Burlington, this report is also available at several locations through out the town. You may pick up a copy at the Vine Brook Water Treatment Plant on Middlesex Turnpike, the Town Hall, or the Library.

Where does my water come from?

The Town of Burlington’s drinking water system contains two separate water treatment plants drawing water from both surface and ground water sources. The Mill Pond Water Treatment Plant treats water from the Mill Pond reservoir. The Mill Pond Treatment Plant has the capacity to treat up to 2.5 million gallons of water per day. The Vine Brook Water Treatment Plant (above) treats water from four ground wells located with in the Vine Brook Aquifer. The Vine Brook Water Treatment Plant has the capacity to treat 1.5 million gallons of water per day.  Both plants filter and clarify the water to remove contaminants, provide fluoridation, corrosion control and disinfections. As of May 2021, we take 1 million gallons of water per day from our emergency pipe connection from the MWRA. Please visit our MWRA page for more information.

What’s a Cross-Connection?

Cross-connections that contaminate drinking water distribution lines are a major concern. A cross-connection is formed at any point where a drinking water line connects to equipment (boilers), systems containing chemicals (air conditioning systems, fire sprinkler systems, irrigation systems), or water sources of questionable quality. Cross-connection contamination can occur when the pressure in the equipment or system is greater than the pressure inside the drinking water line (backpressure). Contamination can also occur when the pressure in the drinking water line drops due to fairly routine occurrences (main breaks, heavy water demand), causing contaminants to be sucked out from the equipment and into the drinking water line (backsiphonage).

Outside water taps and garden hoses tend to be the most common sources of cross-connection contamination at home. The garden hose creates a hazard when submerged in a swimming pool or when attached to a chemical sprayer for weed killing. Garden hoses that are left lying on the ground may be contaminated by fertilizers, cesspools, or garden chemicals. Improperly installed valves in your toilet could also be a source of cross-connection contamination.

Community water supplies are continuously jeopardized by cross-connections unless appropriate valves, known as backflow prevention devices, are installed and maintained. We have surveyed industrial, commercial, and institutional facilities in the service area to make sure that potential cross-connections are identified and eliminated or protected by a backflow preventer. We also inspect and test backflow preventers to make sure that they provide maximum protection.
