The purpose of this article is to safeguard the Village of Springville's potable water supply from potential contamination by preventing backflow from a water user's system into the public water system. It is the intent of this article to recognize that there are varying degrees of hazard and to apply the principle that the degree of protection should be commensurate with the degree of hazard. Further, it is the intent of the Village of Springville to comply with the requirements of the New York State Sanitary Code, Part 5, Section 5-1.31, which section mandates that the supplier of water protect its public water system in accordance with procedures acceptable to the New York State Commissioner of Health. These mandated requirements are as set forth in the Cross-Connection Control Manual published by the New York State Department of Health (NYSDOH) and to that extent, the terms, conditions and provisions of the New York State Sanitary Code, Part 5, Section 5-1.31 and the Cross-Connection Control Manual are incorporated in this article by reference as if fully stated herein.
For this article the following terms shall have the meanings indicated:
AIR GAP SEPARATION
A physical break between a supply pipe and a receiving vessel. The air gap shall be at least double the diameter of the supply pipe, measured vertically above the top rim of the vessel, in no case less than one inch.
APPROVED CHECK VALVE
A check valve that seals readily and completely. It must be carefully machined to have free-moving parts and assured watertightness. The face of the closure element and valve seal must be bronze, composition or other noncorrodible material which will seal tightly under all prevailing conditions of field use. Pins and bushings shall be of bronze and other noncorrodible, nonsticking material, machined for easy dependable operation. The closure element shall be internally weighted or otherwise internally equipped to promote rapid and positive closure in all sizes where this feature is obtainable.
APPROVED DOUBLE-CHECK VALVE ASSEMBLY
Two single independently acting check valves, including tightly closing shutoff valves located at each end of the assembly and suitable test connections. This device must be approved as a complete assembly.
APPROVED REDUCED PRESSURE ZONE DEVICE
A minimum of two independently acting check valves together with an automatically operated pressure differential relief valve located between the two check valves. In case of leakage of either check valve, the differential relief valve, by discharging to the atmosphere, shall operate to maintain the pressure between the checks at less than the supply pressure. The unit must include tightly closing shutoff valves located at each end of the device, and each device shall be fitted with properly located test cocks. This device must also be approved as a complete assembly.
APPROVED WATER SUPPLY
Any water supply approved by the New York State Department of Health for human consumption.
AUXILIARY SUPPLY
Any water supply on or available to the premises other than the approved public water supply.
CERTIFIED BACKFLOW PREVENTION DEVICE TESTER
An individual who has successfully completed a New York State Department of Health-approved course in the testing of backflow prevention devices and has been issued a currently valid certificate by the New York State Department of Health (NYSDOH).
CROSS-CONNECTION
Any connection unprotected against backflow between any part of a water system used or intended to be used as a supply of water for drinking purposes and a source or system containing water or a substance that is not or cannot be approved as equally safe, wholesome and potable for human consumption.
PUBLIC WATER SUPPLY USER
A person(s), partnership, corporation or other entity that owns or occupies property within the Village of Springville that is connected to the Village's public water supply system or has made application for such connection.
VACUUM BREAKER, PRESSURE-TYPE AND NON-PRESSURE-TYPE
A vacuum breaker which can only be used for internal plumbing control and, therefore, not acceptable as a containment device.
WATER SUPERVISOR
The person on the user's premises charged with the responsibility of complete knowledge and understanding of the water supply piping within the user's premises and for maintaining the user's water system free from cross-connections and other sanitary defects, as required by this article and all other existing requirements, regulations and laws.
A. 
Where protection is required. All users of the Village of Springville public water system shall prevent cross-connection between their potable water piping system and any other piping system within the user's premises and between the Village of Springville public water supply system and the user's water system. The user's water system shall be required to maintain a degree of protection commensurate with the degree of hazard regardless of whether the hazard is immediate or potential. To that extent, the Cross-Connection Control Manual published by the NYSDOH shall be used as a guide to determine where protection is required. It shall be the responsibility of the water user to provide, install and maintain such required protection devices, and such devices shall be of a type acceptable to the New York State Department of Health. Plans for the installation of protective devices must be drawn and stamped by a New York State-licensed architect or engineer and submitted by the water user to the Village of Springville for review and to the Erie County Health Department for approval.
B. 
Type of protection. The protective device required shall depend on the degree of hazard as set forth below:
(1) 
Where a residential user of the Village of Springville water supply maintains an auxiliary water supply in addition to the public water supply, the two systems must not be interconnected.
(a) 
Disconnection of the auxiliary water supply from the public water supply. An inspection to determine compliance will be made initially and at least every three years thereafter and whenever the property is sold. The inspection may be made by the Village of Springville's Code Enforcement Officer or his qualified designee.
(b) 
Installation of an approved reduced pressure zone device on the public water supply connection.
(c) 
Proper abandonment of the auxiliary water supply.
(2) 
At the public water supply service connection to any premises on which a substance that would be objectionable (but not necessarily hazardous to health if introduced into the public water supply) is handled so as to constitute a cross-connection, the public water supply shall be protected by an approved double-check valve assembly or an approved reduced pressure zone device or an air gap separation.
(3) 
At the public water supply service connection to any premises on which a substance of unusual toxic concentration or danger to health is or may be handled, but not under pressure, the public water supply shall be protected against backflow by an air gap separation or an approved reduced pressure zone device. If an air gap is installed, it shall be located as close as practical to the water meter, and all piping between the water meter and receiving tanks shall be entirely visible. If an approved reduced pressure zone device is installed, it shall be located as close as possible to the user's side of the water meter.
(4) 
At the public water supply service connection to any premises on which any material dangerous to health or toxic substance and toxic concentration is or may be handled under pressure, the public water supply shall be protected by an air gap separation. The air gap shall be located as close as practical to the water meter, and any piping between the water meter and receiving tanks shall be entirely visible. If these conditions cannot reasonably be met, the public water supply shall be protected against backflow with an approved reduced pressure zone device, and it shall be located as close as possible to the property line.
(5) 
At the public water supply service connection to any sewage treatment plant or sewage pumping station, the public water supply shall be protected by an air gap separation. The air gap shall be located as close as practical to the water meter, and all piping between the water meter and receiving tanks shall be entirely visible. If these conditions cannot be reasonably met, the public water supply shall be protected against backflow by an approved reduced pressure zone device, and it shall be located as close as possible to the user's side of the water meter.
C. 
Frequency of inspection of protective devices. It shall be the duty of the water user on any premises where backflow protective devices are installed to have competent inspections made on a regularly scheduled basis at least once a year or more often as directed by the Village of Springville in instances where successive inspections indicate repeated failure. Devices shall be immediately repaired, overhauled or replaced at the expense of the water user whenever they are found to be defective. These tests shall be performed by a New York State-certified backflow prevention device tester, and all test results shall be provided by the tester to the Village of Springville within 72 hours after the test is made. Records and reports of such tests, repairs and overhaul shall be currently maintained by the user, and copies of the same shall be promptly sent to the Village of Springville and, upon request, made available to the Erie County Health Department.
A. 
No public water service connection to any premises shall be installed or maintained by the water user, unless the public water supply is protected by the water user as required by this article and all other applicable local, state and federal laws, rules and regulations.
B. 
If any public water supply user denies an authorized Village of Springville agent or employee access to its premises for the purposes of determining whether protection of the public water supply system is necessary, then the maximum protection condition shall be imposed with the requirement that the number of devices shall equal the number of water service lines. Denial of such access shall also be deemed prima facie evidence that the appropriate backflow prevention device is not installed in that user's water system.
C. 
In the event that a New York State-certified backflow prevention device tester's report states that a user's required backflow prevention device is not installed or that it is in need of replacement or repair and the Board of Trustees of the Village of Springville determines that water service to that user must be terminated to protect the public health from a grave and immediate danger, such water service shall be terminated by the Village of Springville until an approved and properly functioning backflow prevention device has been installed by the user and verified by such state-certified tester.
D. 
The following penalties shall be applicable for a violation of this article:
(1) 
Failure to install the appropriate backflow prevention device and allow the Village of Springville to verify such installation by on-site inspection and testing within 10 days after first notice given, in writing, personally or by certified mail, to the user or user's water supervisor: $250.
(2) 
Failure to install the appropriate backflow prevention device and allow the Village of Springville to verify such installation by an on-site inspection and testing within 10 days after second notice given as aforesaid: termination of water service.
(3) 
Failure to at least annually test the backflow prevention device as required and provide test results to the Village of Springville: $300 and/or termination of water service.
(4) 
Failure to replace or repair a backflow prevention device as required: $1,000 and/or termination of water service.
