Drinking Water

Exeter's municipal water system provides drinking water and fire protection to the majority of the Town's population. The Town relies on a combination of surface water and groundwater to meet Exeter's water supply needs.  The majority of the water produced in town comes from the Water Treatment Plant.

The primary water supply source is the Exeter River which is pumped to the Water Treatment Plant.  Exeter also uses the Exeter Reservoir which is fed by Dearborn Brook, adjacent to the Water Treatment Plant.  Exeter's groundwater sources include Skinner Springs, Stadium Well, Gilman Well, and Lary Lane well.

Additionally, Exeter's water distribution system includes three storage tanks (Epping Road, Hampton Road, and Cross Road), four pumping stations, and approximately 55 miles of water pipe.

If you are experiencing a water problem with the municipal water supply (no water, low water pressure, odor, red-black-brown water):
