The residents of the City of Norwich receive water from two sources – The Dr. Charles W. Solomon Water Treatment Plant, which draws water from the Deep River Reservoir located in Colchester, and the Stony Brook Treatment Plant and Reservoir located in Montville. Additionally, there are two developable water supplies located in Norwich: the Fairview and Bog Meadow Reservoirs.
There is also a well located in the Yantic area of Norwich, which serves as a backup supply. Each year, our treatment facilities provide approximately 1.6 billion gallons of clean drinking water, or about 4.5 million gallons per day!
The first step in delivering clean drinking water is to protect the source, so NPU diligently monitors and maintains the land and trees that surround the water. Careful attention is paid to trimming back trees that could land in the water and decay. The forest is thinned appropriately, with old trees harvested and sold, and new trees are planted to maintain a healthy barrier. This attention to the health of the surrounding property resulted in being recognized as “Tree Forest of the Year.”
In addition to operating and maintaining the treatment plants and reservoirs, NPU maintains a distribution system containing more than 190 miles of water mains and storage tanks. This distribution system is carefully maintained and tested to ensure the water coming out of your faucet is of the same high quality that leaves the treatment plant. This includes routinely flushing the system twice a year to remove sediment and keep the water clear.

NPU offers free tours of the Deep River Reservoir and Water Treatment Plant to local school groups. Tours take approximately 2-3 hours. For more information, complete a tour request form.

Connecting to City Water:
For information about connecting to the city water supply, contact an NPU Project Coordinator at 860-887-2555 to ensure the availability of city water at your property. NPU project coordinators can be reached Monday through Friday between 8:00 AM and 4:30 PM. The project coordinator will explain the steps and costs involved in connecting your property to the distribution system.
The State of Connecticut Department of Public Health codes require that piping from the well to the house must be disconnected after tying into a public water supply, to prevent contamination of the City’s water supply. Exceptions need to have the approval of the Commissioner of Health. You can get more information, and contact information for the Connecticut Department of health at their web site: www.dph.state.ct.us
5 Steps to Clean, Safe Drinking Water
01Rapid Mix: Water is piped from the reservoir into mixing tanks, where a chemical called Alum is added. Water is mixed at a high rate of speed while the Alum attracts particles (contaminates) in the water. (Similar to how a magnet attracts metal.)
02Slow Mix: Water enters the slow mix tank, where it is mixed at a slower speed. This allows the particles, now called Floc, to form from the impurities and chemicals.
03Sedimentation (Settling): In this 3rd stage, the Floc particles are settled out of the water and collected as sludge. This mud-like substance gets pumped into drying pools. The dry sludge, which is high in minerals and organic materials, is sold to fertilizer companies.
04Sand Filtration: The water, now with the floc particles removed, is filtered through very fie sand and porous bricks to remove the tiniest of impurities. Even though the water is free from all particles, it is not yet safe to drink.
05Disinfection: To remove microscopic organisms (like bacteria and viruses), we are required to add chlorine to the water. Only enough chlorine is added to remove harmful organisms; it is not enough to harm humans or animals. We also add fluoride for healthy teeth.
