As a natural adjunct to its fire-fighting function of supplying water to fire hydrants, and in accordance with the authority granted in its charter, the Harrisville Fire District also supplies potable water to residents of the District. Many of the households in the District are served by Harrisville's water system, as well as four of the five Burrillville schools, the library, and the Town Hall. Harrisville also supplies water to over 150 fire hydrants in the District and Oakland-Mapleville.

The Harrisville Hose Company is the social aspect of the Fire Department. The Hose Company was organized in February of 1912 as a firefighting organization. Today the company supports various community activities within the Town of Burrillville and the village of Harrisville.

The Harrisville Fire Department proudly serves the historic villages of Harrisville and a portion of Glendale in northwest Rhode Island. Its mission is to provide the highest standards of emergency services to all in need and continue our partnership with the community by remaining "Loyal to our Duty." The Fire Department is currently composed of six full time EMT/firefighters, including the Crew Chief. It also has approximately 40 volunteer firefighters, 22 of whom are EMTs, as well as 5 junior firefighters (ages 16-18).
