Hawaii Administrative Rules › Title 10 - DEPARTMENT OF HAWAIIAN HOME LANDS › Chapter 4.1 - MANAGEMENT OF WATER SYSTEMS › Subchapter 1 - GENERAL PROVISIONS › Section 10-4.1-18 - Cross-connection control and backflow prevention

Current through June, 2024
(a) No
				cross-connections shall be made without the written consent of the
				department.
(b) It is unlawful for
				any person to make, maintain, or cause temporarily or permanently, any
				cross-connection that has a potential for backflow between their plumbing pipes
				or water fixtures and the department's water system. Existing cross-connections
				between the department's water system and any auxiliary water supply shall be
				eliminated or protected by means of an approved backflow prevention assembly.
				Cross-connection control and backflow prevention requirements for facilities
				and premises shall be in accordance to this subchapter.
(c) The department may require installation
				of an approved backflow prevention assembly on the consumer's side of the meter
				at the consumer's expense before service will be provided. The department may
				provide for the installation of an approved backflow prevention assembly to
				homestead lots in the service area.
(d) If uninterrupted water service is
				necessary, an additional backflow prevention assembly may be installed in an
				approved manner to ensure continued water service whenever inspection, testing
				and repair procedures is being performed on any one of these
				assemblies.
(e) The backflow
				prevention assembly installed in accordance with these rules shall, unless
				otherwise approved by the department in writing, be located above ground and in
				a manner safe from flooding or submergence in water or other liquid, properly
				protected from external damage, freely accessible, and with adequate working
				room for inspections, testing, and repairing.
(f) All backflow prevention devices shall be
				tested at least once annually and as often as required by the department where
				successive tests indicate repeated failure. Repairs, replacement of parts, or
				any other maintenance shall be made whenever deemed necessary by the department
				and at the expense of the consumer. The annual test shall be the responsibility
				of the consumer and shall be made in accordance with methods approved by the
				department. Upon request by the department, the consumer shall present an
				affidavit certifying that there are no cross connections of the type prohibited
				under this rule on the premises or describing in detail all nonconforming
				connections or installations.
(g)
				Records of tests, repairs, parts, and inspections shall be made on forms
				prescribed by the department and furnished to the department. Failure of the
				consumer to properly test and submit the records may, at the option of the
				department, result in termination of service or the department making the
				tests, repairing and replacing any equipment, and charging the cost to the
				consumer.
(h) When a backflow
				prevention assembly fails in service, the consumer shall notify the department.
				Repairs are the responsibility of the consumer. A certified general tester
				shall perform the testing. Backflow prevention assembly test forms shall be
				completed and sent to the department for confirmation that the device has been
				properly repaired and functions as required. Inspection and approval by the
				department shall be conducted before the device is put back into
				operation.
(i) When the department
				encounters water uses that represent a clear and immediate hazard to the
				department's water supply that cannot be immediately abated, the department
				shall terminate water service at the premises immediately. Written notice shall
				be given to the consumer after water service termination.
(j) For other situations requiring backflow
				protection where there is not apparent and immediate hazard to the water
				supply, the department may terminate water service to a consumer's premises
				after proper notification has been sent.
(k) Conditions relative to the installation
				and maintenance of cross-connection control and backflow prevention referred to
				in this section shall be subject to change to meet changing requirements of
				federal, state, and county laws, ordinances, and rules.
