Water Treatment & Distribution

The Water Treatment Division and Highway and Utilities Division of Concord General Services provide services for the treatment and distribution of potable water in Concord. The City of Concord has five water storage tanks that hold a total of 7.5 million gallons of water, which are used to regulate water distribution and are ready to maintain the water supply to the community in case of emergency situations. The water distribution system in Concord contains 172 miles of piping that delivers potable water to approximately 12,000 service connections.

Life depends on water, yet only 1% of the world’s water is suitable for use. Water is a valuable resource that we use daily for drinking, bathing, cooking, cleaning, agriculture, recreation, and fire protection. Public health depends on safe drinking water, and national standards are enforced to protect the public from contaminants in the water supply. The City of Concord processes the public water supply to meet these standards and to ensure a healthy community.

Imagine A Day Without Water - Open House

Wednesday, October 23rd is "Imagine a Day Without Water." This annual campaign is hosted by The Value of Water Campaign to raise awareness about the importance of water in our daily lives and imagining what even a single day without access to water would mean for a community. Join us for an Open House on Wednesday, October 23rd from 11:00 a.m. to 1:00 p.m. at our Water Treatment Facility (53 Hutchins Street) and/or our Hall Street Wastewater Treatment Facility (125 Hall Street). Celebrate the importance of water with us by touring our facilities and learning more about Concord's water infrastructure. Attendees should be advised that odor emissions have reduced significantly over the years at our Wastewater Treatment Facility through past facility improvements, but some odors are still present due to the natural treatment process. For any questions, please email us at generalservices@concordnh.gov. RSVP to our open house and learn more on our Facebook event page.

Water Treatment Plant

The water treatment plant was built in 1974 and has a 10 Million Gallon per Day (MGD) capacity, but is currently treating an average of 4 MGD for Concord water consumers. Water is used more frequently in the warmer months, so the plant treats an average of 5.5 MGD in the summer. The treatment process is a traditional surface water treatment that involves coagulation, flocculation, sedimentation, and filtration. Treated water is then distributed throughout Concord to provide easy access to one of life’s basic necessities.
