AN ORDINANCE relating to domestic water system service pipes; amending Chapter 7.68
entitled 'Water Division" of the Yakima Municipal Code to clarify
responsibility for the operation and maintenance of the service line;
specify the method for measuring the owners responsibility for leakage,
damage and repair; require the installation of backflow prevention
devices in accordance with the procedure set forth; making minor editing
changes; and specifically amending sections 7.68.035, 7.68.070,
7.68.090 and 7.68.095 of the Yakima Municipal Code.
Section 1. Sections 7.68.035, 7.68.070, 7.68.090 and 7.68.095 of Chapter 7.68 of the City
of Yakima Municipal Code are hereby amended to read as follows:
7.68.035 Service pipes laid by water division.
The installation of service pipes extending from the main to the meter together with the
necessary labor and materials for such construction shall be made by the water/irrigation
division; provided, however, that at the discretion of the water/irrigation division manager,
service pipes extending from the main to the meter may be installed by private contractors
according to water/irrigation division approved plans and specifications; provided further, that all
meters shall be furnished and installed by the water/irrigation division. The water/irrigation
division shall be responsible for the operation and maintenance of the service line from the
water main through the meter set to the outside of the water meter set.
7.68.070 Cross-connection control.
A. Cross-Connections. No water service shall be installed or continued in use by the
purveyor unless the water supply is protected by backflow prevention devices as may be
required by this section. The installation or maintenance of a cross-connection which will
endanger the water quality of the potable water supply of the City of Yakima shall be unlawful
and is prohibited. Any such cross-connection now existing or hereafter installed is declared to
be a public nuisance and the same shall be abated. The control or elimination of cross-
connections shall be in accordance with this section, together with the latest addition of
appropriate manuals of standard practice pertaining to cross-connection control approved by the
Washington Department of Health (DOH). The manager shall have the authority to establish
requirements more stringent than state regulations if he/she deems that the conditions so
dictate. The City of Yakima as the purveyor adopted rules and regulations pursuant to YMC
11.44, the city plumbing code, which shall be used to carry out the provisions of this section.
B. Use of Backflow Prevention Devices.
(1) In the judgment of the purveyor and/or the building official, the backflow prevention
devices shall be installed at the time the service connection is made to the premises or the
materials used in connection with service connection or within any premises where the nature
and extent of the activities, or the materials stored on the premises, would present an immediate
and dangerous hazard to health and/or be deleterious to the, quality of water should a cross-
connection occur. In the judgment of the purveyor and/or the building official backflow
prevention devices shall be required under the listed circumstances, even though such cross-
connection does not exist at the time of installation, which includes but are not limited to the
following:
(a) Premises having an auxiliary water supply, unless the quality of the auxiliary supply is
acceptable to the purveyor.
' -1-
(b) Premises having intemal cross-connections that are not correctable or intricate
plumbing arrangements which make it impracticable to ascertain whether or not cross-
connections exist.
(c) Premises where entry is restricted so that inspections for cross-connections cannot be
made with sufficient frequency or at sufficiently short notice to assure that cross-connections do
not exist.
(d) Premises having a repeated history of cross-connections being established or re-
established.
(e) Premises on which any substance is handled under pressure so as to permit entry into
the public water supply, or where a cross-connection could reasonably be expected to occur.
This shall include the handling of process waters and cooling waters.
(f) Premises where materials of toxic or hazardous nature are handled in such a way that if
back siphonage should occur, a serious health hazard might result.
(g) The following types of facilities will fall into one of the above categories where a
backflow prevention device is required to protect the public water supply. A backflow prevention
device shall be installed at these facilities unless the purveyor and secretary determine that no
hazard exists.
1. Hospitals, mortuaries, clinics;
2. Laboratories;
3. Metal plating industries;
4. Piers and docks;
5. Wastewater treatment plants;
6. Food or beverage processing plants;
7. Chemical plants using a water process;
8. Petroleum processing or storage plants;
9. Radioactive material processing plants or nuclear reactors;
10. Mobile home parks;
11. Others specified by the DOH.
(h) Other premises, as specified by the City plumbing code, YMC 11.44, where backflow
prevention devices are required to protect the public water supply.
(i) Backflow prevention devices, except for devices used as premises isolation shall be
installed by the owner/contractor/developer and inspected by the water/irrigation division and
code administration. Where backflow devices are used as premises isolation, all device and
installation costs shall be borne by the owner/contractor/developer. At the discretion of the
water/irrigation manager the device may be installed by the water/irrigation division or the
owner/contractor/developer and shall be inspected by the water/irrigation division and code
administration.
(2) The type of protective device required shall depend on the degree of hazard which
exists:
(a) An air-gap separation or a reduced pressure principle backflow prevention assembly
shall be installed where the public water supply may be contaminated with wastewater,
industrial waste of a toxic nature, or other contaminant which could cause a high health hazard.
(b) In the case of a substance that does not constitute a high health hazard, a double check
valve assembly, air-gap separation, or a reduced pressure principle backflow prevention
assembly shall be installed.
(3) Backflow prevention devices required by this section shall be installed at the meter, or at
a location designated by the purveyor. The device shall be located so as to be readily
accessible for maintenance and testing, and furthermore, where no part of the device will be
submerged.
(4) Backflow prevention devices required by this section shall not be installed until approved
by code administration and the water/irrigation division.
-2-
(5) The policies, procedures, and criteria for determining appropriate levels of protection
shall be in accordance with the DOH and the "Accepted Procedure and Practice in Cross
Connection Control Manual—Pacific Northwest Section—American Waterworks Association,
Third Edition," or any superseding edition and the City plumbing code, YMC 11.44.
(6) Any protective device required by this section shall be a model approved by the DOH. A
double check valve assembly or a reduced pressure principle backflow prevention assembly will
be approved if it has successfully passed performance tests of the University of Southem
California Engineering Center or other testing laboratories satisfactory to the DOH and the
manager. These devices shall be furnished and installed by and at the expense of the
customer.
(7) Backflow prevention devices installed pursuant to this section, except atmospheric
vacuum breakers, shall be inspected and tested annually or more often if necessary.
Maintenance shall be at the customers expense. Whenever the devices are found to be
defective, they shall be repaired, overhauled, or replaced at the customer's expense.
Inspections, tests, repairs, and records thereof shall be accomplished under the purveyor's
supervision by certified testers and the customer will be charged according to the following
schedule of fees:
(a) For air gap separation inspection, $15.00;
(b) For pressure atmospheric vacuum breaker test, $15.00;
(c) For double check valve assembly test, $25.00;
(d) For reduced pressure backflow assembly test, $25.00.
(8) No underground sprinkling device will be installed without adequate backflow prevention
devices at the point from which the water for irrigation is taken from the public water supply.
(9) Failure of the customer to cooperate in the installation, maintenance, testing or
inspection of backflow prevention devices required by this section and Washington
Administrative Code 246-290 shall be grounds for the termination of water service to the
premises, or, in the altemative, the installation of an air-gap separation at the customer's
expense.
C. Cross-Connection Inspection.
(1) No water shall be delivered to any structure hereafter built within the City of Yakima or
within areas served by the City water until the same shall have been inspected by the code
inspector and the water/irrigation division for possible cross-connections and been approved as
being free of same.
(2) Any construction for industrial or other purposes which is classified as a hazardous
facility pursuant to subsection (B)(1)(g) of this section, where it is reasonable to anticipate
intermittent cross-connections, or as determined by the manager, shall be protected by the
installation of one or more backflow prevention devices at the point of service from the public
water supply or any other location designated by the purveyor.
(3) Inspections shall be made periodically of all buildings, structures, or improvements of
any nature now receiving water through the City's system, for the purpose of ascertaining
whether cross-connections exist. Such inspections shall be made by the purveyor.
D. Installation Permits. If cross-connection control devices are found to be necessary, the
owner of the property served must apply to the City of Yakima code administration and planning
manager for a plumbing installation permit.
E. Additional Remedies. In the event an improper cross-connection is not corrected within
the time limit set by the manager, or, in the event the purveyor is refused access to any property
for the purpose of determining whether or not cross-connections exist, delivery of water to the
property shall cease until the deficiency is corrected to the purveyor's satisfaction. In addition,
the purveyor may affect the necessary repairs or modifications at the expense of the property
owner and refuse delivery of water to the property until the cost thereof shall have been paid.

YAKIMA, WASHINGTON
AGENDA STATEMENT
Item No.
For Meeting Of January 5, 2010
ITEM TITLE: Consideration of an Ordinance Relating to Domestic Water System Service
Pipes and amending Chapter 7.68 of the Yakima Municipal Code
SUBMITTED BY: Dave Zabel!, Assistant City Manager
Dave Brown, Water/Irrigation Manager
CONTACT PERSON/TELEPHONE: Dave Brown / 575-6204
SUMMARY EXPLANATION: Over the past few years there have been some claims against the
city for damages resulting from breaks in domestic water service lines and domestic fire
service lines. There is some difficulty in determining the responsible parties in these claims.
These difficulties were due, in part, to some ambiguities in the Yakima Municipal Code (YMC)
1
defining ownership and responsibilities and a recent change made in the YMC that required
some changes in installation requirements for domestic fire service lines.
0 The ordinance defines the city ownership and responsibility and the property owner's
ownership and responsibility. There are a couple of grammatical corrections and a part of the
YMC that deals with backflow prevention that was moved to the correct section of the YMC.
