[Ord. 86-1974, passed 11-6-1974]
Waterworks ordinance. Reserved rights to enter upon or into any premises where City water is taken, for the purpose of inspection of pipes and fixtures, setting, reading and repairing meters, turning water off and on and enforcing rules generally. Each and every denial of this right will render the offending party liable to penalties prescribed for violation of the rules, i, e. water turn off or fine.
The definition of a cross connection, as based upon the U. S. Department of Health, Education and Public Welfare's Public Health Service Publication No. 525, is any physical connection or arrangement of pipes between two otherwise separate water supply systems, one of which contains potable water and the other water of unknown or questionable safety, whereby water may flow from one system to the other, the direction of flow depending on pressure differential between the two systems.
No cross connection shall be permitted to be made between any system of piping supplied by water from the mains of the Water Bureau and any other source of supply, either public or private; or any secondary supplies known to be unsafe for drinking water, such as shallow wells, reused industrial supplies, raw surface water or swimming pools.
Where City water is used as an auxiliary supply to a roof or suction tank, which is also supplied by water from any other source, such tank shall not be of the pressure type but open. The delivery of City water shall be above the tank flow line and controlled by some type of automatic valve.
It shall be unlawful, also, to maintain storage tanks supplied only with City water, unless the tanks are satisfactorily built, and covered so as to prevent the entrance of contamination. They shall also be subject to periodical inspection by the Water Bureau and maintained in a manner wholly satisfactory to the standards and requirements of the State Department of Health. Pumps taking suction from the City supply, serving such building storage, shall be installed or operated only upon permit from the Water Bureau subject to their approval as to size, capacity and valving arrangements.
It shall be unlawful for anyone to interconnect private supplies, including deep well systems, with the waterworks system except as hereinafter provided:
Correction and maintenance, in a manner satisfactory to the State Department of Health and the City Water Bureau of all existing sanitary defects in and around the private supply system.
Provisions to be made for complete bacteriological analysis by the Water Bureau of the supply involved, in accordance with the standard methods of water analysis of the American Public Health Association. This requirement means not less than four years analyses, conducted each month on two standard samples or more often if the analysis warrants.
Provision by the owner of the private system involved to pay an equitable pro rata part of the cost of all inspections and testing herein required. The rates and method of paying for the same shall be determined by the Water Bureau subject to the approval of Council.
Should any system supplied by City water be operated in violation of any provisions of this article, it shall be the duty of the Water Bureau to completely disconnect all service lines serving such system until this section is properly complied with. Any cost of such disconnection and the estimated cost of reconnection must be paid by the consumer before service shall be restored.
Plumbing code; protection of potable water supply.
Cross connections. Potable and nonpotable water supplies shall be distributed through systems entirely independent of each other, and any cross connection between such supplies is prohibited. Further, no connections shall be made between pipes containing City water and any other pipes, whether or not such other pipes contain water considered potable.
Back-flow. Each fixture supply pipe shall be protected from back-flow by having all outlets from which potable water flows spaced a sufficient distance above the flood level rim of the receptacle into which the water flows to provide a "minimum required air gap" except that where it is not possible to provide a minimum air gap, the fixture shall be equipped with an accessibly located back-flow preventer (see Cross Connection Information Hand Book) installed beyond the manual control valve. Vacuum breakers on aspirators shall be at least 12 inches above waste materials; in funeral homes 18 inches above top of table. The distance for the vacuum breaker on a bed pan sterilizer shall be 24 inches above overflow rim of the fixture. A vacuum breaker shall be installed on all yard hydrants within 50 feet of a swimming pool or any hydrants used for purposes of filling or cleaning pools.
On certain installations such as hospitals, clinics, plating shops, chemical plants, embalming establishments and multi-storied buildings or other buildings or other buildings discharging hazardous materials, back-flow preventors, of a type approved by the Cross Connection Control Chief and the Water Bureau, shall be installed on the building side of the meter.
Color coding. In building or industrial plants where multiple piping systems are used for water, extreme care should be taken not to interconnect the systems. If water from the potable system is used to service systems of lesser quality such as fire protection, plumbing, fixtures, vats, tanks, boilers, sewer ejectors, pumps and numerous other hazardous items, the potable water system must be separated or protected from these dangerous cross connections by an air gap, vacuum breakers, reduced pressure back-flow preventors or double check valves.
Where controlled cross connections are permitted, pipes should be labeled to identify their contents. Each outlet on the nonpotable water line, which may be inadvertently used for drinking water should be posted "Danger Unsafe Water". Other pipes should be painted or banded at appropriate intervals and stenciled to identify their contents and direction of flow. A system that could be used:
OSHA: Federal Safety and Health Act of 1970. There shall be no cross connection between a potable and nonpotable source of water within the premises or plant which can be a potential hazard to employees.
Enforcement. Any customer not complying with the Authority's request to install and maintain back-flow prevention devices will be subject to immediate termination of water service by the Water Authority. In addition to Erie's Water Authority regulations on cross connection control, all customers are required to conform to all definitions hereinafter mentioned.
[Ord. 86-1974, passed 11-6-1974]
Persons making any connections to the public potable water supply system which do not comply with this article are subject to a fine of $500 and the cost of removing the violation.
