Any premises intended for human habitation or occupancy which do not possess a potable water supply or provide sufficient pressure and quantities of water may be declared as unsafe or unfit for human occupancy and may be so tagged by the Health Authority. Any such facility that has been tagged as unsafe or unfit for human occupancy shall be vacated within the time limit specified by the Health Authority.
(A) Surface water supplies. All water systems which receive their source of water from ponds, lakes, streams, rivers, or other surface collectors shall be designed, constructed, and operated in accordance with the Surface Source Water Treatment Code, being 77 Ill. Adm. Code, Pt. 930. No surface water shall be utilized as a potable water supply unless the Health Authority has reviewed and approved the supply and its components.

subchapter;
(2) Renovated in order to be in substantial compliance with construction provisions contained within this subchapter; or
(3) Sealed in accordance with provisions contained within this subchapter.
(D) Backflow protection.
(1) Where water wells are utilized to act as a non-potable water source, the groundwater supplying such wells shall be protected against backflow. Each water outlet shall be protected from backflow by having the outlet end from which the water flows spaced a distance above the flood-level rim of the receptacle or body of water into which the water flows sufficient to provide a minimum fixed air gap. The size of the air gap shall be as specifie in the Illinois Plumbing Code as it applies to the protection of potable water.
(2) Where it is not possible to provide a minimum fixed air gap, the water outlet shall be equipped with an accessible backflow prevention device (for example a vacuum breaker or backflow preventer) complying with either:

(b) Applicable standards of the Illinois Water Well Pump Installation Code, being 415 ILCS 35; 77 Ill. Adm. Code, Pt. 925, for agricultural irrigation as it applies to chemical injection systems. When there is question as to which type of protection device shall be utilized in a given situation, the higher standard of protection shall apply as determined by the Health Authority.
