Department Overview

The Meredith Water and Sewer Department currently services 1,367 customers in Meredith; 822 for both water and sewer, 145 for water only, and 400 for sewer only.

The local sewer collection system consists of approximately 17 miles of sewer mains and five pumping stations. Over the last ten years, the collection system has been extended significantly. This system is part of a regional sewer system known as the Winnipesaukee River Basin Program. Wastewater collected from Meredith and nine other Lakes Region communities is transported via an interceptor sewer and a series of pumping stations to a treatment plant located in Franklin.

Approximately 45% of Meredith's resident population are serviced by the municipal water system. The water supply for this system is Lake Waukewan. The watershed of this 912-acre lake extends into the towns of New Hampton, Center Harbor, Ashland, and Holderness. Treatment of the lake water occurs at a modern filtration plant having a capacity of one million gallons per day. The plant produces approximately 600,000 gallons per day of treated water during the summer peak season. The water is treated to eliminate turbidity, to adjust pH, and to disinfect. The treated water is stored in a 1.5 million gallon water tower, which pressurizes the water distribution system. The system has been extended and improved recently, and now includes approximately 17 miles of water mains.

Mission

The Meredith Water and Sewer Department is committed to providing the community with the safest drinking water possible, and enough supply to meet its demand for both consumption and fire protection. The department adheres to regulations set forth by the Environmental Protection Agency (EPA) and the New Hampshire Department of Environmental Services (NHDES). Lake Waukewan is the town's source for drinking water. For more information on your drinking water, please refer to the annually published Consumer Confidence Report (CCR) which is available online. You can also view a hard copy in town offices.

The water department staff continues proactively maintaining the water treatment plant, two water booster stations, 18 miles of aging water mains, over 100 hydrants, and the town's 1.5 million gallon water tower.

The sewer department maintains the collection system which consists of over 20 miles of sewer mains, five lift stations, and sewer main cleaning activities to keep everything flowing properly.

All waste water is sent through an inter-municipal transmission line to the Winnipesaukee River Basin Treatment Facility in Franklin. This facility is owned and operated by the State of New Hampshire. Its associated expenses account for more than 50% of the town's sewer budget.

The water and sewer department have a combined staff of five employees devoted to safely providing quality customer service to our water customers and sewer customers. Every staff member is licensed to operate both our water and sewer systems. We work seven days a week and are on call 24/7 for emergencies.
