Current through June, 2024
(a) No cross-connections shall be made
				without the written consent of the department
(b) The department requires the installation
				of a mechanical or any other methods or devices on the consumer's side of the
				meter to prevent backflow on all new services at the sole cost and expense of
				the consumer.
(c) Whenever the
				consumer maintains a separate pressure system or separate storage facility, or
				in any way increases the pressure of the water within the premises above the
				pressure furnished by the department, or has the equipment, devices, or
				arrangement of piping, storage, or industrial methods or processes that might,
				under certain circumstances, raise the pressure of the water within the
				premises above the pressure of the water in the mains of the department, a
				backflow prevention device shall be specified and approved by the
				administrator-chief engineer for installation at the sole cost and expense of
				the consumer.
(d) As a protection
				to the consumer's water system, a suitable pressure relief valve shall be
				installed and maintained at the consumer's expense when backflow devices are
				installed on the consumer's side of the meter.
(e) Any device installed for the prevention
				of backflow as may be required under these rules shall, unless the department
				approves otherwise 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 whether
				mechanical or not, shall be tested and inspected internally not less than once
				annually. Repairs, replacement of parts, or any other maintenance, shall be
				made whenever necessary at the expense of the consumer. The annual test and
				inspection shall be the responsibility of the consumer and shall be made in
				accordance with methods recommended by the manufacturers and approved by the
				department. Records of tests and inspections shall be made on formes prescribed
				by 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 the
				department making the tests, repairing and replacing any equipment, and
				charging the cost to the consumer.
(g) Upon request by the department, the
				consumer shall present an affidavit either certifying to the fact that there
				are no connections or installations of the type prohibited under this rule on
				the premises or describing in detail all nonconforming connections or
				installations.
(h) The several
				conditions relative to the installation and maintenance of connections referred
				to in this section shall be subject to change to meet changing requirements of
				the state and county laws, ordinances, and rules.
(i) Failure on the part of the consumer to
				comply with the department's requirements relative to cross-connection and
				backflow protection shall be sufficient reason for discontinuing water service
				until such time that the department's requirements have been met.
