SUBJECT: APPROVE CROSS -CONNECTION CONTROL AGREEMENT WITH
THE IRVINE RANCH WATER DISTRICT
SUMMARY:
The Irvine Ranch Water District has provided Cross -Connection Control services for the
Tustin Water Services since 1999. Recent changes to the statewide cross -connection
standards require an updated agreement between the City and Irvine Ranch Water District
to comply with state regulations.
RECOMMENDATION:
It is recommended that the City Council:
1. Approve the Cross -Connection Control Agreement between Irvine Ranch Water
District and the City of Tustin and authorize the Public Works Director to execute the
agreement on behalf of the City; and
2. Appropriate $70,000 from Water Enterprise Fund 300 for additional services as
outlined in the agreement.
FISCAL IMPACT:
Staff worked closely with the Irvine Ranch Water District in developing the proposed Cross -
Connection Control Agreement (Attachment No. 1) to comply with new statewide cross -
connection standards and reflect the level of service outlined in Tustin's Cross -Connection
Control Management Plan (Attachment No. 2).
The Tustin Cross -Connection Control Management Plan was submitted to the State Water
Resources Control Board on June 30, 2025. The anticipated annual cost to implement this
updated program will increase from $30,000 to $100,000. To fully fund this program, staff
is requesting that the City Council appropriate $70,000 for Fiscal Year 2025-26. Moving
forward, funding will be requested during the City's annual budget process.

CORRELATION TO THE STRATEGIC PLAN:
The Cross -Connection Control Agreement with Irvine Ranch Water District contributes to
the fulfillment of the City's Strategic Plan Goal D: Foster strong relationships within the
community, specifically, Strategy 2, enhance collaborative efforts with agencies within and
outside Tustin on issues of mutual interest and concern.
BACKGROUND AND DISCUSSION:
In December 2023, the California State Water Resources Control Board adopted the Cross -
Connection Control Policy Handbook (Handbook), which establishes new statewide
standards for protecting public water supplies from contamination. The Handbook requires
all domestic water systems to comply with provisions to ensure the prevention of backflow
and cross -connections.
The primary objective of the Handbook is to protect public health by ensuring that public
water systems are safeguarded against backflow incidents. The Handbook promotes a
proactive approach to cross -connection control and provides foundational education for
water suppliers to enhance awareness and understanding of backflow prevention.
Ultimately, its goal is to support the implementation of strong, sustainable cross -connection
control programs across California.
This new Handbook supersedes the previous backflow prevention and cross -connection
control requirements contained in Title 17 of the California Code of Regulations. Under the
updated regulations, each public water system is required to develop and submit a written
Cross -Connection Control Plan to the State Water Board for review by July 1, 2025.
To meet this mandate efficiently and cost-effectively, staff from the City of Tustin
participated in a regional effort with 25 neighboring water agencies to develop a Template
Cross -Connection Control Plan that each agency could customize to reflect the unique
characteristics of their water systems before submission. Staff successfully submitted
Tustin's Cross Connection Control Management Plan to the State Water Resources Control
Board on June 30, 2025.
Since 1999, the Irvine Ranch Water District has provided Cross -Connection Control
services for the City of Tustin Water Services. Irvine Ranch Water District and the City of
Tustin have established a proven, fiscally responsible, and effective partnership over the
past 25 years sharing resources across service boundaries.
It is recommended that the City Council approve the Cross -Connection Control Agreement
between Irvine Ranch Water District and the City of Tustin

CROSS -CONNECTION CONTROL AGREEMENT
This Cross -Connection Control Agreement ("Agreement") is effective as of June , 2025
("Effective Date") and is between Irvine Ranch Water District, a California water district
organized under and existing pursuant to Section 34000 et seq. of the California Water Code
("IRWD"), and the City of Tustin ("City"), each individually known as a "Party" and collectively
known as the "Parties."
A. In December 2023, the California State Water Resources Control Board ("State

requirements identified in the Handbook.
C. Although IRWD has an existing agreement with the City to assist the City in
managing a cross -connection control program that complied with Title 17 of the California Code
of Regulation requirements that were effective prior to the issuance of the Handbook, the new
requirements are more extensive and require IRWD to provide greater resources to the City to
achieve compliance.
D. The Parties seek by this Agreement to set forth the terms under which IRWD will
provide the services necessary to assist the City in managing certain elements of the City's
Control Plan, described in more detail in Section 1 of this Agreement (the "Services"). City will

City of Tustin Cross Connection Control Management Plan (CCCMP)
1 Cross Connection Control Policy Overview
1.1 Objective
The primary objective of the Cross -Connection Control Management Plan (CCCMP) is to bring
the City of Tustin into compliance with the Cross Connection Control Policy Handbook (CCCPH)
developed by the State Water Resources Control Board (State Water Board) for the protection
of public health through the establishment of standards intended to ensure a public water
system's (PWS) drinking water distribution system will not be subject to the backflow of liquids,
gases, or other substances, see CCCMP Appendix A. In addition, by providing basic
educational information on backflow prevention, the City intends to build a foundation of
awareness within the City regarding the importance of backflow protection and cross -connection
control, leading to the implementation of a robust cross -connection control program.
Per Section 3.1.4 (b)(1) description the City will implement the requirements of the State CCCPH
by implementing ordinances, rules and regulations], and procedures as detailed in this CCCMP.
1.2 Applicability
The State CCCPH and its standards apply to all California PWSs, as defined in California's
Health and Safety Code (CHSC, section 116275 (h)). Compliance with the State CCCPH is
mandatory for all California PWSs. The City's CCCMP has been developed in conformance to
the State CCCPH and is applicable to all customers within the City's service area.
1.3 Policy Development Background and Legal Authorities
Through the adoption of the State CCCPH, the State Water Board exercised its authority, under
California's Safe Drinking Water Act (SDWA), to establish enforceable standards applicable to
California's PWSs. Failure to comply with the CCCMP which is in conformance with the State
CCCPH may result in the issuance of compliance, enforcement, or other corrective actions
against the City.
1.4 California Safe Drinking Water Act
On October 6, 2017, Assembly Bill 1671 (AB 1671) was approved and filed with the Secretary
of State (see CCCMP Appendix B). AB 1671 amended California's SDWA through the
establishment of CHSC sections 116407 and 116555.5. AB 1671 also amended section 116810
of the CHSC, which is briefly discussed in CCCPH.
On October 2, 2019, Assembly Bill 1180 (AB 1180) was approved and filed with the Secretary
of State. AB 1180 amended Section 116407 of the CHSC and added section 13521.2 to the
City of Tustin CCCMP —June 2025 1-1

City of Tustin Cross Connection Control Management Plan (CCCMP)
Water Code. AB 1180 requires that the CCCPH include provisions for the use of a swivel or
changeover device (swivel -ell) (see CCCMP Appendix B).
Pursuant to sections 116407 and 116555.5 of the CHSC, the State Water Board chose to adopt
standards for backflow protection and cross -connection control through the adoption of this State
CCCPH, which became effective July 1, 2024.
• The State Water Board is required to adopt regulations for the control of cross -
connections that it determines to be necessary for ensuring PWSs "distribute a reliable
and adequate supply of pure, wholesome, potable, and healthy water." (CHSC section
116375, subd. (c).)
• Any person who owns a PWS is required to ensure that the distribution system will not
be subject to backflow under normal operating conditions. (CHSC section 116555,
subd. (a)(2).)
Prior to AB 1671 and the adoption of the State CCCPH, California's regulations pertaining to
cross -connection control were set forth in regulations in CCR Title 17, which were adopted in
1987 with minor revisions in 2000. Although still protective to public health, the CCR Title 17
cross -connection regulations required updating as both the drinking water and cross -connection
control industries had evolved. This State CCCPH updates those regulations, which as
previously noted are no longer operative following the adoption of the State CCCPH.
The State Water Board may update its standards for backflow protection and cross- connection
control through revisions of the State CCCPH. Prior to adopting substantive revisions to the
State CCCPH, the State Water Board will consult with state and local agencies and persons
identified as having expertise on the subject by the State Water Board, and the State Water
Board will hold at least one public hearing to consider public comments.

2 Hazard Assessments and Required Protection
In accordance with the State CCCPH, Section 3.1.3 (a)(3) — Hazard Assessments, Section 3.1.4
(b)(2), and Section 3.2.1 — The City must survey its service area and conduct hazard
assessments per Article 2 of the State CCCPH that identifies actual or potential cross -connection
hazards, degree of hazard, and any backflow protection needed.
2.1 Hazard Assessments
a. To evaluate the potential for backflow into the City's water distribution system the City
must conduct an initial hazard assessment of the user premises within its service area.
The hazard assessment must consider:
1. The existence of cross -connections;
2. the type and use of materials handled and present, or likely to be, on the user
premises;
3. the degree of piping system complexity and accessibility;
4. access to auxiliary water supplies, pumping systems, or pressure systems;
5. distribution system conditions that increase the likelihood of a backflow event (e.g.,
hydraulic gradient differences impacted by main breaks and high water- demand
situations, multiple service connections that may result in flow -through conditions,
etc.);
6. user premises accessibility;
7. any previous backflow incidents on the user premises; and
8. the requirements and information provided in the State CCCPH, and the City's
CCCMP.
b. Each hazard assessment must identify the degree of hazard to the City's distribution
system as either a high hazard cross -connection, a low hazard cross- connection, or
having no hazard. Examples of some high hazard cross -connection activities may be
found in CCCMP Appendix C.
c. The hazard assessment must determine whether an existing BPA, if any, provides
adequate protection based on the degree of hazard.
d. Hazard assessments completed prior to the adoption of the State CCCPH may be
considered as an initial hazard assessment provided that such hazard assessments and
associated backflow protection provide protection consistent with the State CCCPH and
the City describes their review of these assessments in the City's CCCMP.
e. Subsequent to the initial hazard assessment described in subsection (a), the City must
perform a hazard assessment under the following criteria:
1. if a user premises changes account holder, excluding single-family residences;
2. if a user premises is connected to the City's water distribution system;

City of Tustin Cross Connection Control Management Plan (CCCMP)
3. if evidence exists of changes in the activities or materials on a user's premises;
4. if backflow from a user's premises occurs;
5. periodically, as identified in the City's CCCMP required pursuant to State CCCPH
section 3.1.4.;
6. if the State Water Board requests a hazard assessment of a user's premises; or
7. if the City concludes an existing hazard assessment may no longer accurately
represent the degree of hazard.
f. A cross -connection control specialist must review or conduct each initial and follow-up
hazard assessment pursuant to this section and make a written finding that, in the
specialist's judgment based on cross -connection control principles, the City's hazard
assessment properly identified all hazards at the time of the assessment, the appropriate
degree of hazards, and the corresponding backflow protection.
2.2 Hazard Assessment Process
In order to assess each connection in the City's water distribution system for potential cross
connection the City has contracted with IRWD who will undertake assessments in the following
phases. As part of the hazard assessment process IRWD is has created a tracking system
for the assessments. See IRWD's CCCMP Appendix D.
Data will be gathered and logged into the assessment database in three phases. The
assessment database will be retained per Section 9 — Recordkeeping.
• Phase 1 - All connections with BPA at the meter connection
• Phase 2 - All commercial/industrial connections without BPA at the meter connection
• Phase 3 — Residential connections without BPA at the meter connection
2.2.1 Phase 1- Connections with Backflow Protection
The City currently has 97 connections with a backflow protection installed at the meter as of
5/24/2025. These include commercial, industrial, multi -family residential, and single family
residential. For connections with backflow protection the City will enter each address into the
assessment tracking system indicating what type of BPA has been installed. The City's Cross
Connection Control Specialist will review the data when entered into the assessment database
to verify that an appropriate BPA has been installed on the meter connection. The Cross
Connection Control Specialist's review date will be noted in the assessment database.
It is assumed that a Cross Connection Control Specialist can process (5) connections with a
BPA at the meter connection per available hour, and the total number of annual Cross
Connection Control Specialist available hours is 93 hrs./yr (5% of total annual 1,867 hrs., based
2,080 hrs./yr less 80 hrs./yr for vacation, 45 hrs./yr for sick leave, and 88 hrs./yr for holidays) for
a total of 6 connections with a BPA at the meter connection per year, per Cross Connection
Control Specialist assigned by the City to cross connection control. It is also assumed that
Based on the availability of the Cross Connection Control Project Specialist the City has

City of Tustin Cross Connection Control Management Plan (CCCMP)
determined that this phase of the assessments can be completed within 16.5 years from the
adoption of the City's CCCMP.
2.2.2 Phase 2 — Commercial, Industrial, institutional Connections without Backflow
Protection
The City currently has 2304 commercial, industrial, and multi -family sites without backflow
protection installed at the meter as of 5/25/2025. For those commercial/industrial/institutional
connections without an approved BPA the City will provide a self -reporting letter to provide
information regarding onsite conditions which would necessitate the installation of an approved
BPA at the meter connection. The self -reporting letters will be distributed via direct mail.
The self -reporting letters would be reviewed based on the available Cross Connection Control
Specialist hours to review and process commercial/industrial self -reporting letters and the
expected percent of self -reporting letters returned per distribution.
It is assumed that a Cross Connection Control Specialist can process (5) self -reporting letters
per available hour, and the total number of annual Cross Connection Control Specialist available
hours is 93 hrs./yr (5% of total annual 1,867 hrs., based 2,080 hrs./yr less 80 hrs./yr for vacation,
45 hrs./yr for sick leave, and 88 hrs./yr for holidays) per Cross Connection Control Specialist
assigned by the City to cross connection control. A total of 527 self -reporting letters per year can
be processed by the Cross Connection Control Specialist assigned by the City to cross
connection control.
• If the Cross Connection Control Specialist determines that based on the self -reporting
letter that an approved BPA is not required, they will note that in the assessment database
and the reason for not requiring an approved BPA.
If the Cross Connection Control Specialist determines that based on the self -reporting
letter that an approved BPA is required, they will note that in the assessment database
and notify the commercial/industrial customer that an approved BPA must be installed at
the meter connection and note that determination in the assessment database.
The City has determined that this phase of the assessments can be completed within 4.4 years
from the completion of Phase 1.
2.2.3 Phase 3 — Residential Connections without Backflow Protection
The City currently has 11,991 single family residential and residential condominium sites without
backflow protection installed at the meter as of 5/25/2025. For those single family and residential
condominium connections the City will assess each site by means of office -based tools such as:
Reviewing sites via Google Maps or other aerial photography software
Reviewing tract maps to review blocks of residential customer in a common building area
or zone.

• Using meter route maps or other billing information databases.
The office -based assessment will review sites for:
• Private water wells
• Other auxiliary water supplies
• Sewer lift stations
• Graywater systems
The office -based assessments would be conducted based on the available Cross Connection
Control Specialist hours to review the office -based databases and/or files.
If the Cross Connection Control Specialist determines that based on the office -based
assessment that an approved BPA is not required, they will note that in the assessment
database.
• If the Cross Connection Control Specialist determines that based on the office -based that
an approved BPA is required, they will note that in the assessment database and notify
the residential customer that an approved BPA must be installed at the meter connection
and note that the customer has been contacted in the assessment database.
It is assumed that a Cross Connection Control Specialist can perform (25) assessments by
means of office -based tools per available hour. Assuming that the total number of annual Cross
Connection Control Specialist available hours is 93 hrs./yr (5% of total annual 1,867 hrs., based
2,080 hrs./yr less 80 hrs./yr for vacation, 45 hrs./yr for sick leave, and 88 hrs./yr for holidays) per
Cross Connection Control Specialist assigned by the City to cross connection control. Therefore
422 single family and condominium residential sites can be assessed per year.
Based on the single family and condominium residential sites the City has determined that this
phase of the assessments can be completed within 28.4 years from the completion of Phase 2.

4 Backflow Prevention
In accordance with the State CCCPH, Section 3.1.3 (a)(4) and Section 3.2.2 — the City must
ensure that actual and potential cross -connections are eliminated when possible or controlled
by the installation of approved BPAs or AG's consistent with the requirements of the Article 3 of
the State CCCPH and the sections to follow.
4.1 Backflow Prevention Requirements
(a) The City must ensure its distribution system is protected from backflow from identified
hazards through the proper installation, continued operation, and field testing of an
approved BPA (see Section 4.2.1 for installation and approved BPA criteria). When a
DC is required or referenced in the State CCCPH, a DCDA or DCDA-II type of assembly
may be substituted if appropriate. When an RP is required or referenced in the State
CCCPH, an RPDA or RPDA-II type of assembly may be substituted if appropriate.
(b) The BPA installed must be no less protective than that which is commensurate with the
degree of hazard at a user premises, as specified in this section and as determined
based on the results of the hazard assessment conducted pursuant to CCCMP Section
3.
(c) Unless specified otherwise in this section, the City must, at all times, protect its
distribution system from high hazard cross -connections (see CCCMP Appendix C for

11 Backflow Prevention Assembly Testing and Reporting
In accordance with the State CCCPH, Section 3.1.3 (a)(6) — the City must ensure that each
BPA required by the CCCMP to protect the City's domestic water system is field tested. The
City must develop and implement a procedure for ensuring all BPAs are field tested, inspected,
and maintained and AG's are inspected and maintained in accordance with the State CCCPH,
Section 3.3.3.
All BPAs installed in the City in compliance with CCCMP must be field tested
following installation, repair, depressurization for winterizing, or permanent
relocation. All required field testing must be performed by certified backflow
prevention assembly tester.
2. BPAs must be field tested at least annually. The State CCCPH does not preclude
the City, the State Water Board, or a local health agency from requiring more
frequent field testing for premises with high hazard cross -connection or BPA at
increased risk of testing failure.
3. Air -gap separations must be visually inspected at least annually by a certified as
backflow prevention assembly tester or certified as a cross -connection control
specialist.
4. The City must receive passing field tests before providing continuous service to a
water user with a newly installed BPA.
5. BPAs that fail the field test must be repaired or replaced within 30 days of notification
of the failure by the City. Extensions may be allowed by the City at the discretion of
the Cross Connection Control Specialist.
Backflow prevention assembly testers must notify the City within one day if a backflow incident
or an unprotected cross -connection is observed at the BPA or prior to the user premises during
field testing. The City will immediately investigate and discontinue service to the user premises
if a backflow incident is confirmed, and water service will not be restored to that user premises
until the City receives a confirmation of a passing BPA field test from a backflow prevention
assembly tester and the assembly is protecting the City.
11.1 Backflow Testing Notification Process
Each water user with a BPA on the service connection must comply with the following
schedule in order to be in compliance with the CCCMP and continue to receive water service
from the City.

Appendix A
Background on Backflow Protection and Cross -Connection Control
A.1 What is a Cross -Connection?
A cross -connection is an interconnection between a potable water supply and a non- potable
source via any actual or potential connection or structural arrangement between a PWS and any
source or distribution system containing liquid, gas, or other substances not from an approved
water supply. Bypass arrangements, jumper connections, removable sections, swivel or
change -over devices and other temporary or permanent devices through which, or because of
which backflow can occur are considered to be cross -connections.' The State CCCPH includes
acceptable installation criteria for swivel -ell and other types of backflow prevention assemblies
(BPAs) to prevent backflow.
Backflow is the undesired or unintended reversal of flow of water and/or other liquids, gases, or
other substances into a PWS's distribution system or approved water supply.
The presence of a cross -connection represents a location in a distribution system through which
backflow of contaminants or pollutants can occur. Backflow occurs when a non -potable source
is at a greater pressure than the potable water distribution system. Backflow can occur from
either backsiphonage or backpressure. Backsiphonage occurs when a non -potable source
enters the drinking water supply due to negative (i.e., sub -atmospheric) distribution system
pressure. Backpressure occurs when the pressure from a non -potable source exceeds the
pressure in the potable water distribution system.
Backsiphonage may be caused by a variety of circumstances, such as main breaks, flushing,
pump failure, or emergency firefighting water demand. Backpressure may occur when heating,
cooling, waste disposal, or industrial manufacturing systems are connected to potable supplies
and the pressure in the external system exceeds the pressure in the distribution system. Both
situations act to change the direction of water, which normally flows from the distribution system
to the customer, so that non -potable substances from industrial, commercial, or residential
premises flows back into the distribution system through a cross -connection.
Cross -connections are not limited to industrial or commercial facilities. Submerged inlets are
found on many common plumbing fixtures and are sometimes necessary features of the fixtures
if they are to function properly. Examples of this type of design are siphon -jet urinals or water
closets, flushing rim slop sinks, and dental cuspidors.
Older bathtubs and lavatories may have supply inlets below the flood level rims, but modern
sanitary design has minimized or eliminated this cross -connection in new fixtures. Chemical and
industrial process vats sometimes have submerged inlets where the water pressure is used as
an aid in diffusion, dispersion, and agitation of the vat contents. Even though a supply pipe may
be installed above a vat, backsiphonage can still occur. Siphon action has been shown to raise
a liquid in a pipe such as water almost 34 feet. Some submerged inlets are difficult to control,
City of Tustin CCCMP —June 2025
Docusign Envelope ID: 3C5334C8-3FD2-4FDB-A713-831C664E6E9A
IUJI N
City of Tustin Cross Connection Control Management Plan (CCCMP)
including those which are not apparent until a significant change in water level occurs or where
a supply may be conveniently extended below the liquid surface by means of a hose or auxiliary
piping. A submerged inlet may be created in numerous ways, and its detection may be difficult.
Chemical and biological contaminants have caused illness and deaths during known incidents
of backflow, with contamination affecting several service connections, and the number of
incidents reported is believed to be a small percentage of the total number of backflow incidents
that actually occur. The public health risk from cross -connections and backflow is a function of
a variety of factors including cross -connection and backflow occurrence and type and amount of
contaminants.
A.2 Purpose of a Cross -Connection Control Program
The purpose of a cross -connection control program is to prevent the occurrence of backflow into
a PWS's distribution system in order to protect customers from contamination or pollution from
any on -site hazards. Properly installed and maintained BPAs, devices or methods provide
protection against the threat posed by many conditions typically found on a user's premise.
The use of approved BPAs ensures that the appropriate performance evaluation of the assembly
was conducted. It is important and required by the State CCCPH to select and properly install
an approved BPA that is capable of protecting the distribution system from the hazard identified.
The success of a program depends on individuals that are knowledgeable about cross -
connection control to identify actual and potential hazards, apply principles of backflow
protection and prevention, and implement cross -connection control policies and procedures. A
successful program will have ongoing surveillance of a PWS to ensure BPAs, devices or
methods are working and identify new hazards or changes in the distribution system. Certified
specialists are needed to properly evaluate the degree of hazard that exists in the distribution
system. Hazards typically identified in distribution systems along with the required level of
protection are specified in Chapter 3 of the State CCCPH.
A.3 Notes on Applicability of the Cross -Connection Control Policy Handbook
The State CCCPH provides the basis for regulating the use and management of cross -
connection control programs and BPAs in PWSs, and related requirements for supporting
programs and policies. Activities or uses outside of the scope of the authority of the State Water
Board to regulate PWSs are not regulated by the State CCCPH, including California Plumbing
Code requirements and definitions not related to PWSs.
Recycled water cross -connection control installations and programs for the purposes of
protecting the recycled water supply are not regulated by the State CCCPH, although a PWS
that uses recycled water is regulated by the State CCCPH to ensure that a PWS's drinking water
system has adequate backflow protection from a recycled water system.
Water systems that do not meet the definition of a PWS (e.g., "State Small Water Systems"
under CCR Title 22, Article 3) are not regulated by the CCCPH, although they may need to
comply with the California Plumbing Code, local health agencies, and other laws or entities.

AB 1671, Caballero. Backflow protection and cross -connection controls:
standards.
(1) Existing law, the California Safe Drinking Water Act, requires the State
Water Resources Control Board to administer provisions relating to the regulation
of drinking water to protect public health, including, but not limited to, conducting
research, studies, and demonstration projects relating to the provision of a
dependable, safe supply of drinking water, enforcing the federal Safe Drinking
Water Act, adopting regulations, and conducting studies and investigations to
assess the quality of private domestic water wells. Existing law makes certain
violations of the act a misdemeanor.
Existing law requires any person who owns a public water system to ensure that
the system does certain things, including, but not limited to, that it will not be subject
to backflow under normal operating conditions. Existing law, to ensure that testing
and maintenance of backflow prevention devices are performed by persons qualified
to do testing and maintenance, authorizes local health officers to maintain programs
for certification of backflow prevention device testers and requires the certification
program to be consistent with backflow protection regulations adopted by the state
board. A violation of these provisions, or an order by a local health officer pursuant
to these provisions, is a misdemeanor.
This bill would require a public water system to implement a cross -
connection control program that complies with, and would require the certification
program to be consistent with, applicable regulations and the standards described
in (2).
(2) Existing regulations establish standards for a backflow prevention device
and cross -connection control.
This bill, on or before January 1, 2020, would require the state board to adopt
standards for backflow protection and cross -connection control and would
authorize the state board to do so through the adoption of a policy handbook, as
specified. By authorizing the state board to adopt standards, the violation of which
would be a crime, the bill would create a new crime and impose a state -mandated
local program.

Swivel -Ell Design and Construction Criteria
The criteria below, in conjunction with the swivel -ell diagrams that follow (Diagrams A and B),
are minimum acceptable design and construction -related requirements for utilizing a swivel -
ell. For restrictions and allowances for utilizing a swivel -ell, see CCCPH section 3.2.2.
A. Prior to operation of a swivel -ell, the PWS will receive approval for the design and
construction plans of that swivel -ell from the State Water Board.
B. The drinking water supply must not, under any circumstances, be directly connected
to the recycled water supply, nor be designed such that the recycled water use site
could be supplied concurrently by a recycled water supply and a drinking water supply.
C. The drinking water supply line and the recycled water supply line must be offset (see
Diagram 9b) in a manner that ensures a tee -connection, spool, or other prefabricated
mechanical appurtenance(s) could not be readily utilized in lieu of the swivel -ell
connection, nor result in the recycled water use site being supplied concurrently by
recycled water and drinking water.
D. The recycled water supply line used in conjunction with the swivel -ell must be the only
recycled water supply to the recycled water use area.
E. The swivel -ell must be located as close as practical to the public water system service
connection, with the swivel -ell connection being located as close as practical to the RP
upstream of the swivel -ell.
F. The swivel -ell must
1. be located above ground;
2. be color -coded pursuant to section 116815 of the CHSC and its implementing
regulations;
3. include appropriate signage, as required by regulation and the State Water
Board;
4. be provided the security necessary to prevent interconnections, vandalism,
unauthorized entry, etc.; and
5. be provided with meters on both the recycled water service and drinking water
service connections.
