SECONDARY WATER SUPPLY. A water system maintained in addition to the village water system, including, but not limited to, water systems from ground or surface sources not meeting the requirements of Public Act 399 of 1976, being M.C.L.A. §§ 325.1001 to 325.1023, or water from a public water supply which in any way has been treated, processed, or exposed to any possible contaminant or stored in other than an approved storage facility.
