A. Responsibility For Backflow Prevention: It is the responsibility and financial obligation of the consumer to prevent backflow into the public water supply system by ensuring that:
1. All cross connections are removed or approved cross connection control devices are installed for control of backflow and backsiphonage.
2. Cross connection control devices shall be installed in accordance with the manufacturer's instructions.
3. Cross connection control devices shall be inspected at least annually by a person approved by the agency as a cross connection control device inspector (CCDI). The inspection of mechanical devices shall include physical testing in accordance with the manufacturer's instructions on an annual basis.
4. Testing And Records:
a. Each device shall be tested at least annually by a certified CCDI or more frequently if recommended by the manufacturer or commissioner.
b. Original records submitted to the commissioner shall be available for inspection by agency personnel in accordance with 415 Illinois Compiled Statutes 5/4(e). These original records shall be maintained by the village.
c. Each device shall have a tag attached listing the date of the most recent test, name of CCDI and type and date repairs.
d. A maintenance log shall be maintained and include:
(1) Date of each test;
(2) Name and approval number of person performing the inspection or test;
(3) Test results/inspection;
(4) Repairs or servicing required;
(5) Repairs and date completed; and
(6) Services performed and date completed.
B. Required Backflow Prevention Devices:
1. An approved backflow prevention device shall be installed on each water service line to a consumer's water system when, in the judgment of the commissioner, actual or potential hazards to the public water supply system may exist.
2. An approved backflow prevention device shall be installed on each water service line to a consumer's water system where the following conditions exist:
a. Premises having an auxiliary water system, unless such auxiliary water system is accepted as an additional source by the commissioner and the source is approved by the agency and local authority.
b. Premises where any substance exists which can create an actual or potential hazard to the public water supply system.
c. Premises having internal cross connections that, in the judgment of the commissioner, are not correctable or intricate plumbing arrangements which make it impractical to determine whether or not cross connections exist.
d. Premises where, because of security requirement or other prohibitions or restrictions, it is impossible or impractical to make a complete cross connection survey.
e. Premises having a repeated history of cross connections being established or reestablished.
3. An approved backflow prevention device shall be installed on each water line to a consumer's water system serving, but not necessarily limited to, the following types of facilities, unless the commissioner determines that no actual or potential hazard to the public water supply system exists:
Car washes.
Fertilizer/chemical plants.
Food or beverage processing plants.
Hospital, mortuaries, clinics, nursing homes.
Laboratories.
Lawn sprinkler systems.
Metal plating industries.
Petroleum processing or storage plants.
Radioactive material processing plants or nuclear plants.
Sewage treatments plants, sewage pumping stations or storm water pumping stations.
C. Types Of Protection Required:
1. The type of protection required shall depend on the degree of hazard which exists as follows:
a. An approved fixed air gap shall be installed where the public water supply system may be contaminated causing a severe health hazard.
b. An approved fixed air gap or an approved reduced pressure zone principal backflow prevention device shall be installed where the public water supply system may be contaminated causing a system or health hazard.
c. An approved fixed proper air gap separation or an approved reduced pressure zone principal backflow prevention device shall be installed where the public water supply system may be polluted with substances that could cause a pollution hazard dangerous to health.
2. Where a public water supply or an auxiliary water supply is used for a fire protection system, reduced pressure principal backflow preventers shall be installed between the fire sprinkler systems connected to the public water supply system when:
a. The sprinkler system contains antifreeze and/or chemical additives.
b. Water may be pumped into the system from another source, and/or nonpotable water supply can be connected to the sprinkler system.
D. Approved Backflow Prevention Devices:
1. All backflow prevention devices, methods, installation and maintenance required by these rules and regulations shall be approved by the commissioner.
2. Approval shall be based on the Research Foundation for Cross Connection Control of the University of Southern California, American Water Works Association, American Society of Sanitary Engineering or American National Standards Institute or certified by the American National Standards Institute or certified by the National Sanitation Foundation to be in compliance with applicable industry specifications. A manufacturer's maintenance manual shall be available on site. (Ord. 1-98, 3-3-1998)
