About Us
The Portsmouth Water and Fire District is a quasi-municipal agency established by the Rhode Island General Assembly in 1952. The District is responsible for providing municipal water and fire protection services to approximately 90% of Portsmouth on Aquidneck Island.
The District is governed by an elected seven-member Administrative Board with elections held annually on the second Wednesday of June. While separate from the Town of Portsmouth government, the District collaborates closely with town officials to serve their shared constituents effectively.
Originally named the Island Park and Common Fence Point Fire District, the water distribution system was constructed during the 1950s. In 1956, the name changed to Portsmouth Water and Fire District. Service boundaries expanded in 1965 to include southern Portsmouth, with infrastructure development following in the late 1960s. The Redwood Facilities and Raytheon areas remain outside the District's service area as they receive water from Newport.
Today, the District maintains an extensive system serving 6,638 customers that includes:
- Over 140 miles of pipeline
- 4 water storage tanks
- 2 pumping stations
- 582 fire hydrants
The District purchases wholesale water from the City of Newport and maintains an emergency supply connection with Stone Bridge Fire District in Tiverton. The Administrative Board is committed to providing residents with sufficient quantities of the highest quality water available.
Recent service improvements include:
- Online payment portal for water and tax bills via ACH drafts and credit/debit cards
- Geographic Information System (GIS) implementation for water system mapping
- Property Management System web application for record-keeping and mobile work orders
- Preparation for replacing the 51-year-old Union Street Pumping Station
- Annual water main flushing program based on hydraulic modeling
- Strategic looping of water main extensions to eliminate dead-ends
- Cross-connection control program implementation
- CodeRED emergency notification system
The District encourages public participation in decisions affecting municipal water. Regular Administrative Board meetings are held the third Tuesday of each month at 7:00 PM at the District office (1944 East Main Road). The public is welcome to attend these meetings.

Your water supply comes primarily from nine surface water reservoirs managed by Newport Water. These include Lawton Valley Reservoir, Sisson Pond, and St. Mary's Pond in Portsmouth; Nonquit Pond in Tiverton; Watson Reservoir in Little Compton; North and South Easton Ponds in Middletown/Newport; and Paradise and Gardner Ponds in Middletown.
Most water treatment occurs at the Lawton Valley Water Treatment Plant in Portsmouth, with occasional processing at Station 1 Water Treatment Plant in Newport. For emergency situations, the District can access water from Stone Bridge Fire District's treatment plant, which draws from Stafford Pond in Tiverton.
A 2003 assessment by the University of Rhode Island, in cooperation with the Rhode Island Department of Health, found that water sources on Aquidneck Island and in Little Compton and Tiverton are moderately vulnerable to contamination. This assessment was updated in 2010, highlighting the ongoing importance of monitoring and protection efforts to maintain water quality.
