RULES AND REGULATIONS FOR WATER SERVICE CONNECTIONS

WITHIN THE COUNTY OF KAUAI, AND PROVIDING PENALTIES

FOR THE VIOLATION THEREOF

SECTION XX - CROSS-CONNECTIONS AND BACKFLOW PROTECTION

1.            Prohibition of Certain Conditions and Installations.  In order to provide proper sanitary protection to the Department’s water supply and to comply with the applicable regulations of the United States Public Health Service and of the State Department of Health, as adopted or amended from time to time, the Department will require that following the effective date of these rules and regulations no cross-connections with other water supplies, or other physical connections, shall exist, or be installed, located, maintained or operated which could permit backflow of contaminated water or any other dangerous, impure, unsanitary, or unpotable substance from the consumer’s premises into the Department’s water supply system, except as provided below:

a.         Cross-Connections with Other Water Supplies.  Owners (or operators) of presently existing water supplies which are in active use and cross-connected to the Department’s system will be required to secure permits for the continuance of such cross-connections.  Permits will be granted on a provisional basis renewable yearly, under the following conditions:

(1)            Where such water supplies are regularly examined by the Department, or other agencies satisfactory to the Department and are approved by the Department as acceptable, safe and sanitary supplies and continue as such at all times while connections are in existence.

(2)            Where such water supplies do not meet the requirements of (1) above, are not normally under pressure and are maintained solely for the fire fighting purposes, and where adequate protection against backflow to the Department’s water system is provided by mechanical, or other methods or devices satisfactory to the Department.

(3)            The Department may waive the requirement of a permit and allow cross-connections to be continued or established if the connections are with water supplies defined as primary or community supplies by the State Department of Health as acceptable, safe and sanitary supplies.

b.         Other Physical Connections.  Other physical connections may be permitted if, in the judgement of the Department, adequate protection can be provided the water supply of the Department against backflow by the installation of mechanical, or other methods or devices approved by the Department and installed, maintained and operated by the consumer in a manner satisfactory to the Department at all times; provided, however, that the Department may require the consumer to eliminate or re-arrange designated plumbing or piping connections or fixtures, or to install a backflow device at the meter or other location, subject to the approval of the Department, as an added safety measure in addition to any and all other backflow protection required or provided by mechanical, or other methods of devices, whenever (1) the consumer is engaged in the handling of dangerous or corrosive liquids or industrial or process waters, highly contaminated water or sewage, or is engaged in the medical or dental treatment of persons who might have diseases transmittable by water, or whenever (2) in the judgement of the Department there exists a danger of backflow in the Department’s mains because of the possibility of unauthorized connections being created through noncompliance or inadvertence on account of the complexity of the system or systems, or for any other sufficient reason or cause.

2. Separate Pressure System.  The Department will require the installation of mechanical, or other, methods or devices on the consumer’s side of the meter to prevent backflow whenever the consumer maintains a separate pressure system or a separate storage facility, or in any way increases the pressures of the water within his premises above the pressure furnished by the Department or has such equipment devices or arrangement of piping, storage or industrial methods or processes that might under certain conditions raise the pressure of the water within his premises above the pressure of the water in the mains of the Department.  Plans for such installation must be approved by the Department.

3.            Pressure Regulation required of Consumer.  As a protection to the consumer’s plumbing system, a suitable pressure relief valve must be installed and maintained by him at his expense when backflow devices are installed on the consumer’s side of the meter.

4.            Location and Inspection of Protective Devices.  Any device installed for the prevention of backflow, as may be required under these rules and regulations, shall, unless the Department approves otherwise in writing, be located above ground and in such a manner as to be safe from flooding or submergence in water or other liquids, properly protected from external damage, freely accessible and with adequate working room for inspections, testing and repairing.

All such devices shall be tested at least annually and inspected internally not less than once every two years.  Repairs, replacement of parts, etc., shall be made whenever necessary at the expense of the consumer.  Making of tests and annual inspections shall be the responsibility of the consumer and shall be made by the consumer or other qualified person or persons in accordance with methods acceptable to the Department.  Record of tests and inspections shall be made on forms prescribed by the Department and a copy of such records shall be furnished to the Department.  Failure of the consumer to make the proper tests and submission of records may, at the option of the Department, result in the Department’s making tests, needed repairs and replacements and charging the costs thereof to the consumer.

5.            Affidavits of Compliance.  Upon request of the Department, the consumer shall present an affidavit either certifying to the fact that there are no connections or other installations of the type prohibited in paragraph 1 of this Section on his premises or describing in detail all non-conformity connections or installations.

6.            Conformance with Laws and Ordinances.  The several conditions relative to the installation and maintenance of cross-connections and other physical connections referred to in this Section shall be subject to change to meet changing requirements of the State and Federal health authorities and of the Kauai County Building Code then in existence.

7.            Discontinuance of Water Service for Non-Compliance.  Failure on the part of the consumer to comply with the Department’s requirements relative to cross-connections and backflow protection will be sufficient reason for discontinuing water service until such time as the requirements have been met.

8.         The standards booklet, entitled “The Cross-Connections and Backflow Protection” shall be used in conformance with Paragraphs 1 through 7 of this section.

            Copies of the booklet can be picked up at the Department of Water.
