(A) In certain instances, backflow protection is required by the very nature of the use to which the public water system is connected.
(B) Connections to which backflow protection is required are as hereafter identified.
(1) An approved backflow prevention device shall be installed on each service line to a consumer’s water system serving premises where, in the judgment of the village, its authorized representative or the State Department of Health, actual or potential cross-connections exist. The type and degree of protection required shall be commensurate with the degree of hazard and/or type of contamination that may enter the public water supply system.
(2) An approved air gap separation or reduced pressure principle backflow prevention device shall be installed at the service connection or within any premises where, in the judgment of the village, its authorized representative or the State Department of Health, the nature and extent of activities on the premises, or the materials used in connection with the activities, or materials stored on the premises, would present a health hazard or contamination of the public water supply system from a cross- connection. This includes, but is not limited to, the following situations:
(a) Premises having an auxiliary water supply, unless the quality of the auxiliary supply is acceptable to the village, its authorized representative or the State Department of Health;
(b) Premises having internal plumbing arrangements which make it impractical to ascertain whether or not cross-connections exist;
(c) Premises where entry is restricted so that inspection for cross-connections cannot be made with sufficient frequency or at sufficiently short notice to assure the cross-connections do not exist;
(d) Premises having a repeated history of cross-connections being established or reestablished;
(e) Premises which, due to the nature of the enterprise therein, are subject to recurring modification or expansion;
(f) Premises on which any substance is handled under pressure so as to permit entry into the public water supply system or where a cross-connection could reasonably be expected to occur. This shall include the handling of process waters and cooling waters; and
(g) Premises where toxic or hazardous materials are handled.
(3) The following types of facilities fall into one or more of the categories or premises where an approved air gap separation or reduced pressure principle backflow prevention device may be required by the village, its authorized representative or the State Department of Health, to protect the public water supply and must be installed at these facilities unless all hazardous or potentially hazardous conditions have been eliminated or corrected by other methods to the satisfaction of the village, or its authorized representative, and the State Department of Health:
(a) Agricultural chemical facilities;
(b) Auxiliary water systems, wells;
(c) Boilers;
(d) Bulk water loading facilities;
(e) Car washes, automobile servicing facilities;
(f) Chemical manufacturing, processing, compounding or treatment plants;
(g) Chill water systems;

(i) Fire protection systems;
(j) Hazardous waste storage and disposal sites;
(k) Hospitals, mortuaries, clinics or others as discovered by sanitary surveys;
(l) Lawn irrigation systems and swimming pools;
(m) Laundries and dry cleaning;
(n) Meat processing facilities;
(o) Metal manufacturing, cleaning, processing and fabricating plants;
(p) Oil and gas production, refining, storage or transmission properties;
(q) Plating plants;
(r) Power plants;
(s) Research and analytical laboratories;
