On Thursday, November 3, 2022, Norwich Public Utilities (NPU) will reactivate its Stony Brook Water Treatment Plant in Montville following the completion of an important upgrade to improve water quality for its customers.

Beginning at 7:00 pm on Thursday, NPU will begin flushing the water main from the plant to the area adjacent to I-395 as part of bringing the plant back on line. As a result, approximately 600 customers in the western portion of Norwich and the Oakdale section of Montville could experience minimal and temporary water pressure fluctuations in the overnight hours of Thursday into Friday morning.

It is also possible that there will be minor issues with water color during this time. Despite the difference in the water’s appearance, the water remains safe for human consumption and all other uses. Opening the cold water tap and allowing the water to run for several minutes will help move this process along.

NPU is conducting this work during the evening and overnight hours to minimize any inconvenience for residential and commercial customers.

Earlier this fall, NPU completed its Dissolved Air Filtration (DAF) project that will improve water quality and upgrade the Stony Brook treatment plant. The DAF project pumps air into the filtration process, which brings organic material to the surface of the water being treated; these materials can then be more thoroughly removed from the water as it is prepared for distribution to the public.
