TREATMENT PROCESS


Chemung River


Hoffman Storage Reservoir

Well Site Under Rehabilitation

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

The treatment process starts with a blending of the two sources of water supply during transmission to the coagulation basin. The water is then dosed with chemicals to remove particles and adjust 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.
