Watertown’s water and sewer rates will be rising after the Town Council approved the new rates, but they also had questions about how the rates increased as the amount of water used dropped. The new rates will include a 2.5 percent increase for water rates and 4.9 percent for sewer rates, for a combined increase of 4 percent. The average customer would pay an extra $13.42 per quarter, or 15 cents a day. See more details about the rates by clicking here. The Council heard a presentation at the end of May about the proposed rates, and the rates that were adopted were identical to the recommendations from the town’s water and sewer consultant.
