[HISTORY: Adopted by the Town Board of the Town of Stillwater as indicated in article histories. Amendments noted where applicable.]
Article I Cross-Connection Control
[Adopted 12-16-2010 by L.L. No. 2-2011]
It is the purpose of this article to protect the public potable water supply of the Town of Stillwater from the possibility of contamination or pollution by isolating within the customer's internal distribution system(s) or the customer's private water system(s) such contaminants that could backflow into the Town's water system; to promote the elimination or control of existing cross-connections, actual or potential, between the customer's in-plant potable water system(s) and nonpotable water systems, plumbing fixtures, and industrial piping systems; and to provide for the maintenance of a continuing program of cross-connection control that will systematically and effectively prevent the contamination or pollution of all potable water systems.
Further, it is the intent of the Town of Stillwater to comply with the requirements of the New York State Sanitary Code, Part 5, Section 5-1.31, which said section mandates the requirement of the supplier of water to protect their water system in accordance with the procedures acceptable to the 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 into this article by reference as if more fully stated.
The Town of Stillwater Highway Superintendent/Water Commissioner shall be responsible for the protection of the public potable water distribution system from contamination or pollution due to the backflow of contaminants or pollutants through the water service connection. If, in the judgment of the Highway Superintendent/Water Commissioner, an approved backflow-prevention assembly is required (at the customer's water service connection or within the customer's private water system) for the safety of the water system, the Highway Superintendent/Water Commissioner shall give notice in writing to said customer to install such an approved backflow-prevention assembly(ies) at specific location(s) on his/her premises. The customer shall immediately install such approved assembly(ies) at his/her own expense, and failure, refusal, or inability on the part of the customer to install, have tested, and maintain said assembly(ies) shall constitute grounds for discontinuing water service to the premises until such requirements have been satisfactorily met.
As used in this article, the following terms shall have the meanings indicated:
- Accepted by the Town of Stillwater as meeting an applicable specification stated or cited in this article as suitable for the proposed use.
- AUXILIARY WATER SUPPLY
- Any water supply on or available to the Town of Stillwater other than the purveyor's approved public water supply. These auxiliary waters may include waters from another purveyor's public potable water supply or any natural source(s), such as a well, spring, river, stream, harbor and so forth; used waters; or industrial fluids. These waters may be contaminated or polluted, or they may be objectionable and constitute an unacceptable water source over which the water purveyor does not have sanitary control.
- The undesirable reversal of flow in a potable water distribution system as a result of cross-connection.
- A pressure, higher than the supply pressure, caused by a pump, elevated tank, boiler, or any other means that cause backflow.
- Backflow caused by negative or reduced pressure in the supply piping.
- An impairment of a potable water supply by the introduction or admission of any foreign substance that degrades the quality and creates a health hazard.
- A connection or potential connection between any part of a potable water system and any other environment containing other substances in a manner that, under any circumstances, would allow such substances to enter the potable water system. Other substances may be gases, liquid or solids, such as chemicals, waste products, steam, water from other sources (potable or nonpotable), or any matter that may change the color or add odor to the water.
- CROSS-CONNECTION CONTROL BY CONTAMINANT
- The installation of an approved backflow-prevention assembly at the water service connection to any customer's premises, where it is physically and economically unfeasible to find and permanently eliminate or control all actual or potential cross-connections within the customer's water system; or the installation of an approved backflow-prevention assembly on the service line leading to and supplying a portion of a customer's water system where there are actual or potential cross-connections that cannot be effectively eliminated or controlled at the point of the cross-connection.
- CROSS-CONNECTION, CONTROLLED
- A connection between a potable water system and a nonpotable water system with an approved backflow-prevention assembly properly installed and maintained so that it will continuously afford the protection commensurate with the degree of hazard.
- HAZARD, DEGREE OF
- The term is derived from an evaluation of the potential risk to public health and the adverse effect of the hazard upon the potable water system.
- INDUSTRIAL FLUIDS SYSTEM
- Any system containing a fluid or solution that may be chemically, biologically, or otherwise contaminated or polluted in a form or concentration such as would constitute a health, system, pollution, or plumbing hazard if introduced into an approved water supply. This may include, but not be limited to, polluted or contaminated waters; all types of process waters and used waters originating from the public potable water system that may have deteriorated in sanitary quality; chemicals in fluid form; plating acids and alkalies; circulating cooling waters connected to an open cooling tower and/or cooling towers that are chemically and biologically treated or stabilized with toxic substances; contaminated natural waters, such as wells, springs, streams, rivers, bays, harbors, seas, irrigation canals or systems and so forth; oils, gasses, glycerin, paraffins, caustic and acid solutions; and other liquid and gaseous fluids used in industrial or other processes or for fire-fighting purposes.
- The presence of any foreign substance in water that tends to degrade its quality so as to constitute a nonhealth hazard or impair the usefulness of the water.
- SERVICE CONNECTION
- The terminal end of a service connection from the public potable water system; that is, where the water purveyor loses jurisdiction and sanitary control over the water and its point of delivery to the customer's water system. If a meter is installed at the end of the service connection, then the "service connection" shall mean the downstream end of the meter. There should be no unprotected takeoffs from the service line ahead of any meter or backflow-prevention assembly located at the point of delivery to the customer's water system. "Service connection" shall also include water service connections from a fire hydrant and all other temporary or emergency water service connections from the public potable water system.
- WATER, NONPOTABLE
- Water that is not safe for human consumption or that is of questionable quality.
- WATER, POTABLE
- Water that is safe for human consumption as described by the public health authority having jurisdiction.
- WATER, USED
- Any water supplied by a water purveyor from a public potable water system to a consumer's water system after it has passed through the point of delivery and is no longer under the sanitary control of the water purveyor.
The utility system shall consist of the source facilities and the distribution system and shall include all those facilities of the water system under the complete control of the utility, up to the point where the customer's system begins.
The source shall include all components of the facilities utilized in the production, treatment, storage, and delivery of water to the distribution system.
The distribution system shall include the network of conduits used for the delivery of water from the source to the customer's system.
The customer's system shall include those parts of the facilities beyond the termination of the utility distribution system that are utilized in conveying utility-delivered domestic water to points of use.
No water service connection to any premises shall be installed or maintained by the water purveyor unless the water supply is protected as required by state laws and regulations and this article. New York State cross-connection control laws and regulations can be found on the Cross-Connection Control Program page on the New York State Department of Health website; www.health.state.ny.us. An application for approval of backflow-prevention devices (DOH-347) must be submitted to the New York State Department of Health; an application form can be obtained from the Department of Health website or by contacting the Department of Health at the following address: New York State Department of Health, Bureau of Public Water Supply Protection, 547 River Street, Flanigan Square, Room 400, Troy, NY 12180-2216, or call 1-800-458-1158, ext. 27650. Service of water to any premises shall be discontinued by the water purveyor if a backflow-prevention assembly required by this article is not installed, tested, and maintained, or if it is found that a backflow-prevention assembly has been removed, bypassed, or if an unprotected cross-connection exists on the premises. Service will not be restored until such conditions or defects are corrected.
The customer's system should be open for inspection at all reasonable times to authorized representatives of the Town of Stillwater to determine whether cross-connections or other structural or sanitary hazards, including violations of these regulations, exist. When such a condition becomes known, the Highway Superintendent/Water Commissioner shall deny or immediately discontinue service to the premises by providing for a physical break in the service line until the customer has corrected the condition(s) in conformance with state and city statutes relating to plumbing and water supplies and the regulations adopted pursuant thereto.
An approved backflow-prevention assembly shall be installed on each service line to a customer's water system at or near the property line or immediately inside the building being served, but, in all cases, before the first branch line leading off the service line wherever the following conditions exist:
In the case of premises having an auxiliary water supply that is not or may not be of safe bacteriological or chemical quality and that is not acceptable as an additional source by the Highway Superintendent/Water Commissioner, the public water system shall be protected against backflow from the premises by installing an approved backflow-prevention assembly in the service line, appropriate to the degree of hazard.
In the case of premises in which any industrial fluids or any other objectionable substances are handled in such a fashion as to create an actual or potential hazard to the public water system, the public water system shall be protected against backflow from the premises by installing an approved backflow-prevention assembly in the service line, appropriate to the degree of hazard. This shall include the handling of process waters and waters originating from the utility system that have been subject to deterioration in quality.
In the case of premises having internal cross-connections that cannot be permanently corrected and controlled or intricate plumbing and piping arrangements or where entry to all portions of the premises is not readily accessible for inspection purposes, making it impracticable or impossible to ascertain whether or not dangerous cross-connections exist, the public water system shall be protected against backflow from the premises by installing an approved backflow-prevention assembly in the service line.
The type of protective assembly required under Subsection B(3)(a), (b) and (c) shall depend upon the degree of hazard that exists as follows:
In the case of any premises where there is an auxiliary water supply as stated in Subsection B(3)(a) and it is not subject to any of the following rules, the public water system shall be protected by an approved air gap separation or an approved reduced-pressure-principle backflow-prevention assembly.
In the case of any premises where there is water or substances that would be objectionable but not hazardous to health if introduced into the public water system, the public water system shall be protected by a double-check valve assembly.
In the case of any premises where there is any material dangerous to health that is handled in such a fashion as to create an actual or potential hazard to the public water system, the public water system shall be protected by an approved air gap separation or an approved reduced-pressure-principle backflow-prevention assembly. Examples of premises where these conditions will exist include sewage treatment plants, sewage pumping stations, chemical manufacturing plants, hospitals, mortuaries, and plating plants.
In the case of any premises where there are uncontrolled cross-connections, either actual or potential, the public water system shall be protected by an approved air gap separation or an approved reduced-pressure-principle backflow-prevention assembly at the service connection.
In the case of any premises where, because of security requirements or other prohibitions or restrictions, it is impossible or impractical to make a complete in-plant cross-connection survey, the public water system shall be protected against backflow from the premises by either an approved air gap separation or an approved reduced-pressure-principle backflow-prevention assembly on each service to the premises.
In the case of any premises where, in the opinion of the Highway Superintendent/Water Commissioner, an undue health threat is posed because of the presence of extremely toxic substances, the Highway Superintendent/Water Commissioner may require an air gap at the service connection to protect the public water system. This requirement will be at the discretion of the Highway Superintendent/Water Commissioner and is dependent on the degree of hazard.
Approved backflow-prevention assemblies.
Any backflow-prevention assembly required herein shall be a model and size approved by the Highway Superintendent/Water Commissioner. The term "approved backflow-prevention assembly" shall mean an assembly that has been manufactured in full conformance with the standards established by the American Water Works Association titled "ANSI/AWWA C510-89, Standard for Double Check Valve and Backflow-Prevention Assembly," and "AWWA C511-89, Standard for Reduced-Pressure Principle Backflow Prevention Assembly," and has met completely the laboratory and field performance specifications of the Foundation for Cross-Connection Control and Hydraulic Research (FCCCHR) of the University of Southern California established by "Specification of Backflow-Prevention Assemblies," Section 10, of the most current issue of the Manual of Cross Connection Control.
Said AWWA and FCCCHR standards and specifications have been adopted by the Executive Director. Final approval shall be evidenced by a certificate of approval issued by an approved testing laboratory certifying full compliance with said AWWA standards and FCCCHR specifications.
The following testing laboratory has been qualified by the Highway Superintendent/Water Commissioner to test and certify backflow preventers: Foundation for Cross-Connection Control and Hydraulic Research, University of Southern California, University Park, Los Angeles, CA 90089.
Testing laboratories, other than the laboratory listed above, will be added to an approved list as they are qualified by the Highway Superintendent/Water Commissioner.
Backflow preventers that may be subjected to backpressure or backsiphonage that have been fully tested and have been granted a certificate of approval by said qualified laboratory and are listed on the laboratory's current list of approved backflow-prevention assemblies may be used without further testing or qualification.
It shall be the duty of the customer-user at any premises where backflow-prevention assemblies are installed to have certified inspections and operational tests made at least once per year. In those instances where the Highway Superintendent/Water Commissioner deems the hazard to be great enough, certified inspections may be required at more frequent intervals. These inspections and tests shall be at the expense of the water user and shall be performed by a tester certified by the New York State Department of Health in accordance with Section 5-1.31 of the New York State Sanitary Code. It shall be the duty of the Highway Superintendent/Water Commissioner to see that these tests are made in a timely manner. The customer-user shall notify the Highway Superintendent/Water Commissioner in advance when the tests are to be undertaken so that the customer-user may witness the tests if so desired. These assemblies shall be repaired, overhauled, or replaced at the expense of the customer-user whenever said assemblies are found to be defective. Records of such tests, repairs, and overhaul shall be kept and submitted to the Highway Superintendent/Water Commissioner.
All presently installed backflow-prevention assemblies that do not meet the requirements of this section but were approved assemblies for the purpose described herein at the time of installation and that have been properly maintained shall, except for the inspection and maintenance requirements under Subsection B(6), be excluded from the requirements of these rules so long as the Highway Superintendent/Water Commissioner is assured that they will satisfactorily protect the utility system. Whenever the existing assembly is moved from the present location, requires more than minimum maintenance, or when the Highway Superintendent/Water Commissioner finds that the maintenance constitutes a hazard to health, the unit shall be replaced by an approved backflow-prevention assembly meeting the requirements of this section.
No water service connection to any premises shall be installed or maintained by the water user unless the water supply is protected as required by this article and such other applicable local, state and federal laws, rules and regulations.
If any facility served by a water system denies a Water Department representative access to their premises for the purposes of determining if protection to the public water is necessary, then the maximum protection condition shall be imposed with the requirement that the number of devices shall equal the number of service lines.
The following penalties shall be applicable for a violation of this article:
Failure to install the appropriate backflow-prevention device within a prescribed time frame after first notice: $250.
Failure to install the appropriate backflow-prevention device within a prescribed time frame after the second notice: termination of water service.
Failure to at least annually test the backflow-prevention device: $300 and/or termination of water service.
Failure to replace or repair a backflow-prevention device as required: $1,000 and/or termination of water service.
