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.

7.68.070 Cross-connection control.
A. Cross-Connections. No water service shall be installed or continued in use by the
134.irveyor 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-
•I -1 -
connection occur. In the judgment of the purveyor and/or the building official backflow
411
prevention devices shall be required under the listed circumstances, even though such cross-
connection does not exist at the time of iostallation4aatinstallation, 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.
(b) Premises having internal 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 perrnit 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;

(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 waterlirriqation 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.
- 2-
• (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.
(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—Arnerican 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

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 alternative, 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
