Haw. Code R. § 4-157-19 - Cross-connections
(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.
