No water service connection shall be installed or maintained to any premises where actual or potential cross-connections to this water system may exist. This prohibition shall include cross-connections with the private system of a consumer which are utilized in conveying water from this water system to points of use. No person shall install or maintain any connection whereby water from an auxiliary water supply may enter the water system or the private system unless such auxiliary water supply and the method of connection and use of such supply shall have been approved by the Borough.
The owner of any premises shall install an approved backflow preventor prior to the first branch line leading off each service line to the private system of the premises which was in service on January 21, 1993, where, in the judgment of the Borough, an actual or potential hazard to the water system exists.
A. 
An approved backflow preventor shall be installed on each service line to a private system where the following conditions exist:
(1) 
Systems having an auxiliary water supply, unless the Borough accepts such auxiliary supply as an additional source and the DEP approves the additional source.
(2) 
Systems where any substance is handled in such a fashion as to create an actual or potential hazard to the water system. This shall include systems having sources or auxiliary systems containing process fluids or waters originating from the water system which are no longer under the sanitary control of the Borough.
(3) 
Systems having internal cross-connections that, in the judgment of the Borough, are not correctable or intricate plumbing arrangements which make it impractical to determine whether or not cross-connections exist.
(4) 
Systems where, because of security requirements or other prohibitions or restrictions, it is impossible or impractical to make a complete cross-connection survey.
(5) 
Systems having a repeated history of cross-connections being established or reestablished.
(6) 
Others specified by the Borough.
B. 
An approved backflow preventor shall be installed on each service line to a private system serving, but not necessarily limited to, the following types of facilities unless the Borough determines that no actual or potential hazard to the water system exists.
(1) 
Hospitals, mortuaries, clinics, nursing homes, and medical and dental offices.
(2) 
Laboratories.
(3) 
Laundromats.

C. 
The owner of a premises shall install an approved backflow preventor within 120 days after receipt of notification from the Borough that a backflow preventor is required to be installed.
D. 
An approved backflow preventor shall not be required to be installed on any fire suppression system existing as of January 21, 1993, where the lateral connected to the water system is used to provide service solely to the fire suppression system. If the lateral which connects to the water system is also used to provide water for other purposes within the premises, the owner shall install a backflow preventor in accordance with the requirements of this article. The owner of a premises shall install backflow preventors upon all new fire suppression systems and upon all fire suppression systems which are substantially modified and/or upgraded between the point of connection of the lateral with the water system and the first line of sprinkler heads. Owners of premises containing fire suppression systems which are not required to install backflow preventors under the terms of this subsection shall annually have the fire suppression system inspected to insure that the first check valve(s) downstream from the water system installed as a part of the fire suppression system is in operating condition. The inspection shall be performed by a member of the National Fire Sprinkler Association or other qualified inspector acceptable to the Borough. A copy of the inspection report shall be provided to the Borough upon completion of the inspection.
All residential and nonresidential customers which shall connect to the water system after January 21, 1993, shall install an approved backflow preventor in accordance with the requirements of this article. The backflow preventor shall be inspected by a representative of the Borough prior to commencement of water service.
The failure or refusal to install a backflow preventor when notified by the Borough that a backflow preventor is required to be installed or the failure to install a backflow preventor in the private system of any person who becomes a consumer of the water system after January 21, 1993, shall be grounds for termination of water service. Water service shall not be restored to the premises until the owner has installed a backflow preventor in accordance with the requirements of this article and such backflow preventor has been inspected by a Borough representative and all fees required for the reestablishment of water service have been paid.
The type of protection required under §§ 196-31 and 196-32 of this article shall depend on the degree of hazard which exists as follows:
A. 
An approved air gap separation shall be installed where the water system may be contaminated with substances that are dangerous to the public health and could cause a severe health hazard.
B. 
An approved air gap separation or an approved reduced pressure zone backflow prevention device shall be installed where the water system may be contaminated with a substance that could cause a system or health hazard.
A. 
Any backflow preventor required by this article shall be of a model or construction approved by the Borough and shall comply with the following:
(1) 
The air gap separation shall be at least twice the diameter of the supply pipe, measured vertically above the top rim of the vessel, but in no case less than one inch.
(2) 
A backflow preventor to be installed in any building containing more than one residential dwelling unit or any nonresidential use shall be a device that has been manufactured in full conformance with standards established by the AWWA entitled AWWA C510 Double Check Valve Backflow Prevention Assembly and AWWA C511 Reduced Pressure-Principle and Backflow Prevention Assembly. The Borough hereby adopts said AWWA standards. Final approval, however, of the reduced-pressure principle backflow preventor and the double check valve assembly shall be evidenced by a certificate of full approval issued by an approved testing laboratory certifying full compliance with the AWWA standards.
(3) 
A backflow preventor to be installed in any building containing not more than one residential dwelling unit shall be a device that has been manufactured in full conformance with standards established by ASSE Standard 1024 or a device which complies with the standards incorporated by Subsection A(2) above.
(4) 
An interchangeable connection to be approved shall be either a swing type connector or a four-way valve of the lubricated plug type that operates through a mechanism which unseats the plug, turns it 90° and reseats the plug. Four-way valves shall not be used as stop valves but shall have separate stop valves on each pipe connected to the valve. The telltale port on the four-way valves shall have no piping connected and the threads or flange on this port shall be destroyed so that a connection cannot be made.
B. 
Existing backflow preventors approved by the Borough at the time of installation and properly maintained shall, except for inspection and maintenance requirements, be excluded from the requirement of Subsection A above, provided the Borough is assured that they will satisfactorily protect the water system. Whenever the existing device is moved from the present location or requires more than minimum maintenance or when the Borough finds that the maintenance of the device constitutes a hazard to health, the device shall be replaced by a backflow preventor meeting the requirements of this article.
C. 
An approved air gap separation or an approved reduced pressure zone backflow preventor or an approved double check valve assembly shall be installed where the water system may be polluted with substances that would be objectionable but not dangerous to health.
A. 
The owner of the premises shall be responsible to install any backflow preventor this article requires at a location and in a manner approved by the Borough and by a person properly qualified.
B. 
Backflow preventors installed on the service line to a private system shall be located on the consumer's side of the water meter, as close to the meter as reasonably practical, and prior to any other connection.
C. 
Pits or vaults shall be of watertight construction, be so located and constructed as to prevent flooding and shall be maintained free from standing water by means of either a sump pump or a suitable drain. Such sump pump or drain shall not connect to a sanitary sewer nor permit flooding of the pit or vault by reverse flow from its point of discharge. Vaults or pits shall be a minimum twenty-four-inch diameter manhole access opening or a 24 inch by 24 inch access hatch. An access ladder and adequate natural or artificial lighting shall be provided to permit maintenance inspection and testing of the backflow preventor. Vault or pit construction shall conform to ASTM C-478 for round vaults or ACI 318 for rectangular vaults. All vault or pit joint sealing materials and pipe gasketing materials shall conform to the requirements identified in the section governing construction of manholes and all vault or pit access steps shall conform to the requirements for manhole steps in the Rules and Regulations Concerning Extensions of the Borough's Sewer System.
The owner of the premises shall properly maintain all backflow preventors and appurtenances installed to insure proper functioning of the backflow preventor. As part of this maintenance, the consumer shall insure that adequate clearances are maintained around the backflow preventor to permit inspection by Borough representatives.
[Amended 3-26-2018 by Ord. No. 645]
All owners of residential dwelling units in which backflow preventers have been installed shall permit Borough representatives access to the installation of the backflow preventer at reasonable times for the purpose of inspecting the backflow preventer to ensure proper installation and functioning. Owners of nonresidential uses shall ensure that the backflow preventer is inspected once every three years to ensure proper installation and functioning. Such inspections shall be performed by a certified backflow prevention device tester, and the property owner shall forward a copy of the inspection report to the Borough no later than December 31 of the third year following the last inspection. Refusal to permit access to the backflow preventer for Borough inspection or refusal to submit an inspection report by a certified backflow prevention device tester as set forth herein shall be grounds for termination of water service in order to ensure the safety of the water system by the prevention of backflow into the water system.
