INTRODUCTION

1.1 BACKGROUND

The City operates two water reclamation facilities: North City Water Reclamation Plant and the South Bay Water Reclamation Plant. Both plants produce “disinfected tertiary recycled water” which is defined in Title 22 of the State of California Code of Regulations (60301.230 CCR). Title 22 was adopted to ensure proper health protection and specify the treatment degree to match the intended use. Recycled water may be used for a variety of non-potable uses, including but not limited to:

irrigation of parks, playgrounds and school yards, residential and commercial landscaping, golf courses, and agriculture (ornamental and food crops) industrial or commercial cooling or air conditioning flushing toilets and urinals industrial process water fire fighting decorative fountains, enhancement of wildlife habitat, and recreational impoundment construction purposes, including soil compaction, dust control, and mixing concrete freeway and cemetery landscaping

The use of water recycled from municipal wastewater is regulated by the California Regional Water Quality Control Board (RWQCB) under the City’s Master Permits (Order No. 2000-203 and R9-2015-0091). These permits require the City to establish and enforce rules and regulations for recycle water use including governing the design and construction of recycled water use facilities (13523.1 California Water Code).

In 1989, with the City’s adoption of the Water Reclamation Ordinance 0-17327, section 64.0801-64.0808 of the municipal code was added or updated to govern the use and distribution of recycled water in areas that can or may in the future be served by recycled water in lieu of potable water.

1.2 POLICY

It is the policy of the City that recycled water be used for any purpose approved for recycled water use when it is economically, financially, and technically feasible, as mandated by the San Diego Municipal Code. Use of potable water for non-domestic uses shall be contrary to the City policy, and shall not be considered the most beneficial use of a natural resource and shall be avoided to the maximum extent possible.

The distribution and use of recycled water shall be consistent with the standards and requirements of regulatory agencies for the protection of public health and welfare, and the preservation of the quality of the environment. Nothing in these rules and regulations is intended to undermine state or federal statutes or regulations.

1.3 PURPOSE

The Rules and Regulations set forth herein pertain to recycled water service provided by the City within the City’s service area. These Rules and Regulations establish procedures for the distribution and use of recycled water. Recycled water service from the City is subject to the availability of facilities and adequate capacity in these facilities.

It is the general intent of the City to provide recycled water to all service areas in the City identified in the Water Reclamation and Reuse Conceptual Master Plan for Modifications to the Metropolitan Sewerage System, and subsequent additions, revisions or updates of the plan, herein referred to as “Master Plan”. Owners or property identified as being in a class of potential users in the Master Plan within areas for recycled water use shall qualify for a recycled water Use Permit from the City in compliance with these Rules and Regulations.

These Rules and Regulations shall be interpreted in accordance with the purpose, policy, and intent of these Rules and Regulations and the definitions as set forth in Section 2 herein.

Insofar as these Rules and Regulations support portions of the California Health & Safety Code, Water Code and Code of Regulations (Title 22 and Title 17), any amendment of these codes, which may be pertinent to these Rules and Regulations, shall be incorporated accordingly.

1.4 GOALS

Recycled water shall be distributed and used in a manner that meets all State, County, and City requirements, including these Rules & Regulations, and which shall achieve the following:

a. Prevent direct human contact of recycled water through adherence to all applicable rules and regulations and laws.

b. Prevent cross-connection between recycled and potable water systems which include a strict cross-connection/backflow prevention program.

Because recycled water is not processed to the point that it is acceptable for human consumption, it is important that these Rules and Regulations contain provisions which minimize or eliminate the possible misuse of the recycled water.

3.9.4 Services to Common Areas

The City reserves the right to supply recycled water to contiguous areas of a single ownership through a single recycled water service connection.

Common areas owned or operated by home owner associations or similar cooperatives should have only one service connection whenever it is practical, and will be operated as a single ownership. A recycled water service connection and water meter shall not be used to supply property not covered by the permit authorizing the connection.

3.9.5 Subdividing an Approved Service Area

a. When a property provided with a recycled water service connection and water meter is subdivided, such connection and meter shall be considered as serving a lot or parcel of land on which the meter is located. Additional recycled water distribution mains and/or service lines will be required for all subdivided areas in accordance with these Rules and Regulations, unless the sub divider provides covenants, conditions, and restrictions (CC&R’s) properly recorded with the County Recorder for the operation of onsite recycled water facilities serving more than one lot, and also provides easements for recycled water distribution mains and/or service lines or shows easement locations in the CC&R’s.

b. All recycled water used on any premise where a meter is installed must pass through the meter. Customers shall be charged for all recycled water passing through the meter.

c. Every recycled water service connection and meter assembly shall include a curb cock or wheel valve, as approved by the City, on the inlet side of the meter, which shall be used exclusively by the City for controlling the recycled water supply through the recycled water service line. If the curb cock or wheel valve is damaged by the customer’s use, repair and/or replacement by the City shall be at the customer’s expense.

d. Each customer shall restrict the use of recycled water to those uses set forth in the

Use Permit for recycled water services approved by the City.

3.9.6 Temporary Discontinuation of Recycled Water Service

By reason of circumstances beyond the control of the City, or in order to protect the facilities of the City, or for the protection of public health, safety and welfare of the residents or property owners of the City, recycled water service may be terminated under the conditions set forth below:

a. On a temporary basis at any time the recycled water, at the terminal point of the

City’s water reclamation plant takeoff, does not meet the requirements of the regulatory agencies, including but not limited to those prescribed by the California

Code of Regulations, Title 22. Recycled water service would, in such case, be renewed at such time that recycled water at the terminal point of the water reclamation plant would again meet the requirements of the regulatory agencies or at such time that the City would supplement the recycled water system from the potable or disinfected raw water system.

b. When the City determines that a water shortage exists or is threatened which prevents further recycled water service.

c. When a meter is found to be out of service or is not registering, the system will be shut down until the meter is serviced and inspected.

3.9.8 Conditions of Pressure and Service

Pressure and service shall be provided on an as available basis, at the location of the customer’s meter. The Public Utilities Department Director shall state the desirable pressure of the system in the department’s design guide. All customers shall hold the City harmless from any and all damages and liabilities caused in whole or in part by pressure conditions, water quality variations, or interruptions in service. It shall be the owner’s responsibility to install booster pumps or increase pressure if necessary.

3.10 SIZE AND LOCATIONS OF SERVICE CONNECTIONS

The City reserves the right to determine the size and location of recycled water service lines, the service connections, and the meters. The City shall also have the right to determine the kinds and sizes of backflow prevention devices and any and all other appurtenances to the service.

3.11 ILLEGAL CONNECTIONS

No person shall make any connection to recycled water facilities of the City without a permit from the City. Penalties for violations may be assessed according to Section 9 of these Rules and Regulations.

3.12 CROSS-CONNECTION PREVENTION

3.12.1 Purpose

The primary purpose of a cross-connection program is to protect the potable water system from possible contamination by prohibiting and preventing cross-connections between the potable water system and the recycled water system, in accordance with Title 17, Chapter 5 of the California Code of Regulations. The secondary purpose is to protect the recycled water system from other contaminants. The following provisions are in additions to, and not in lieu of, the controls and requirements of other regulatory agencies, such as the County of San Diego DEH and State Water Resources Control Board Division of Drinking Water.

3.12.2 Backflow Prevention

Regulations governing backflow prevention devices are intended to protect the City’s potable water supplies and are not intended to protect users from potential hazards of cross-connections in the user’s onsite facilities.

City approved backflow prevention for the potable water system shall be provided by the user in accordance with the specifications of the Public Utilities Department. Provisions, installation, maintenance and inspection of backflow prevention devices shall be the sole responsibility and duty of the customer, and at customer’s expense. Inspection of backflow prevention devices shall be done at least once a year, or more often in those instances where successive inspections indicate repeated failures. These devices shall be inspected, repaired, overhauled or replaced at the expense of the customer whenever they are found to be defective. Records of such tests, repairs, and overhauls shall be kept by the City, and such records shall be made available to any concerned regulatory agency on request.

The installation and inspection of backflow prevention devices shall be done by a certified inspector at the expense of the customer. The customer shall submit original inspection certificates as proof of compliance to the City Public Utilities Department, Cross Connection Control Section, 9192 Topaz Way, MS. 901, San Diego, CA 92123. All inspection and testing shall be done to the satisfaction of the City and the regulatory agencies concerned.

3.12.3 Type of Protection

The type of protection shall be provided to prevent backflow into the potable water system and shall be commensurate with the degree of hazard that exists on the consumer’s premises. The type of protective device that may be required (listed in an increasing level of protection) includes: Double check Valve Assembly-(DC), Reduced Pressure Principle Backflow Prevention Device-(RP) and an air gap Separation-(AG).

The water user may choose a higher level of protection than required by the water supplier. The minimum types of backflow protection required to protect the water supply with various degrees of hazard, are given in Table 1. Situations not covered in Table 1 shall be evaluated on a case-by-case basis and the appropriate backflow protection shall be determined by the City of San Diego and County DEH.
