Water source

Water within the Northfield city limits is supplied from a groundwater source via four wells that range in depth from 365 to 410 feet. Water is drawn from the Jordan aquifer. Fluoride, chlorine, and polyphosphates are fed into the water system at each individual well site as the water is pumped into the water distribution system. Polyphosphates are used to reduce problems with discolored water.


The water system includes three 1-million-gallon storage tanks. This storage provides the necessary degree of water pressure and ensures an adequate supply of water for responding to a fire, even on the hottest days of summer when water demand is greatest.
