The Elmira Water Board, with treatment and distribution facilities throughout Chemung County, also services 1,253 fire hydrants.

Treatment Process

The Elmira Water Board has two sources of water supply: surface water and ground water. The surface water sources are the Chemung River and the Hoffman Creek Reservoir. The ground water sources are the Foster Island Wells and the Hudson Street Wells.

The treatment process starts with a blending of the two sources of water supply during transmission to the coagulation basin. Chemicals are then added to the water in order to remove particles and adjust the pH. Over a six hour detention time, the processes of coagulation and sedimentation occurs and chlorine is added.   

After settling, the decant water flows into the treatment plant for filtration. The water circulates through 12 inches of filter sand and 18 inches of anthracite coal for final polishing. The filtered water is then post chlorinated and fluoride is added to reduce tooth decay.
