California City Municipal Code Art. 6 Usage

Operation and surveillance of off-site facilities shall be by the City. No person except authorized employees of the City shall enter upon, inspect, operate, adjust, change, alter, move, or relocate any portion of the off-site facilities. Such action may also be in violation of Federal, State, and local statutes, ordinances, regulations, and other requirements.

(a) The operation and maintenance of on-site facilities are the responsibility of the customer.

(b) The operation and maintenance of on-site facilities shall be by an ?on-site Recycled Water Supervisor? designated by the customer and approved by the City. The City may require an ?on-site Recycled Water Supervisor? obtain instruction in the use of recycled water provided by the City.

(c) The General Manager shall monitor and inspect the on-site facilities, and for these purposes may enter on the customer's premises during reasonable hours. Where necessary, keys or combinations shall be issued to provide such access.

(d) The customer shall have the following responsibilities in relation to operation of on-site facilities:

(1) To ensure personnel are trained and familiarized with the use of recycled water;

(2) To furnish personnel with maintenance instructions, irrigation schedules, and record drawings to ensure proper operation in accordance with the on-site facilities design and these regulations;

(3) To submit to the City one set of record drawings on Mylar;

(4) To notify the City of proposed changes, modifications, or additions to the on-site facilities. Changes shall be approved by the City and shall be designed and constructed according to the requirements, conditions, and standards set forth in the City's "Guidelines of Recycled Water Facilities" conditions, and standards, changes must be submitted to the City for plan check and approval prior to construction. The construction shall be inspected by the City, and revised record drawings and controller charts shall be approved by the City.

(5) To ensure the on-site facilities continue to comply with these regulations;

(6) To operate and control the system to prevent direct human consumption of recycled water and to control and limit runoff. The customer is responsible for subsequent uses. Operation and control measures shall include the following:

(i) On-site facilities shall be operated to prevent or minimize discharge into areas not under control of the customer. Part circle sprinklers shall be used adjacent to sidewalks, roadways, and property lines to confine the discharge from sprinklers to the design area.

(ii) The operation shall be during the periods of minimal use of the service area. Consideration shall be given to allow a maximum dry-out time before the design area will be used by the public.

(iii) Recycled water shall be applied at a rate that does not exceed the infiltration rate of the soil. Where varying soil types are present, the design and operation of the on-site facilities shall be compatible with the lowest infiltration rate present.

(iv) To prevent runoff and ponding, automatic systems shall be used and programmed to prevent or minimize the ponding and runoff of recycled water. The sprinkler system shall not be allowed to operate for a time longer than the landscape's water requirement. If runoff occurs before the landscape's water requirements are met, the automatic controls shall be reprogrammed to lessen watering cycles to meet the requirements. This method of operation is intended to control and limit runoff.

(v) To report an unauthorized discharge of recycled water.

(7) To comply with Federal, State and local statutes, ordinances, regulations, contracts, these Rules and regulations, and requirements prescribed by the General Manager and the Board.

It is the desire of City to effect conservation of water resources whenever possible, such measures being consistent with legal responsibilities to seek to wisely utilize the water resources of the State of California and the City.

No irrigation of new or existing parks, median strips, landscaped public areas or landscaped areas, lawns, or gardens surrounding single family homes, condominiums, townhouses, apartments, and industrial parks shall occur in such a way as to waste water. The rate and extent of application of water shall be controlled by the consumer so as to minimize runoff from the irrigated areas.

(a) If recycled water meter fails to register during any period, or is known to register inaccurately, the customer shall be charged with an average daily consumption at the same season shown by the reading of the meter when in use and registering accurately. A customer may demand the meter through which water is being furnished be examined and tested by the City for the purpose of ascertaining whether or not it is correctly registering the amount of recycled water being delivered. Such demand shall be in writing and shall be accompanied by a deposit equal to the potable monthly service fee for sized meter.

(b) Upon receipt of such demand and deposit, the City will have the meter examined and tested, and if upon such test the meter shall be found to register over 2% more water than actually passed through it, the meter shall be properly adjusted or another meter substituted therefor, the deposit shall be returned, and the recycled water bill for the current month will be adjusted proportionately. If the meter should be found to register not more than 2% more water than actually passes through it, the deposit shall be retained by the City to offset the expense of making the test.

( Ord. No. 16-744, § 11, 12-13-2016 )

These provisions protect the potable water supply against actual or potential cross-connection by isolating the premises where contamination or pollution may occur because of some undiscovered or unauthorized cross-connection, and to prevent cross-connections in accordance with the California Code or Regulations. These provisions are in addition to the controls and requirements of other regulatory agencies. These regulations are not intended to provide protection of users from the hazards of cross-connections within their own premises.

Backflow prevention devices, on the potable water service to the premises shall be provided by the customer. Such devices shall be owned and maintained by the City, and located on the premises, but shall not be on the City's portion of the system.

(a) On-site facilities are a separate and controlled non-potable system. Under normal conditions, protective devices will be required on the City's potable water service. Under no circumstances will the City tolerate an actual or potential cross-connection between the City's potable water supply and the Customer's on-site non-potable water facilities.

(b) The City will require a backflow prevention device on its potable water supply:

(1) When recycled water is used on individually owned and controlled; and

(2) When the recycled water system has additional pressure.

The type of protection device shall be determined by the City. A backflow protective device shall be required on the potable pipeline and shall consist of a reduced pressure principle backflow device.

The City shall inspect backflow prevention devices at least annually. Inspection and testing shall be performed by a tester certified by the local health department. The devices shall be repaired, overhauled, or replaced at the expense of the customer when found to be defective. Records of tests, repairs, and overhauls shall be maintained and made available to the local health department.

Where the premises contain dual or multiple water systems and piping, the exposed portions for recycled water pipelines shall be painted, banded, or marked at sufficient intervals. Outlets from secondary or other potentially contaminated systems shall be posted as being contaminated and unsafe for drinking purposes.

(a) The City will notify the local and State Health Departments, and the Regional Water Quality Control Board of the identity of the person responsible for the on-site facilities. Where necessary, a water supervisor shall be designated. This water supervisor shall be responsible for the installation and the use of pipelines and equipment and for the prevention of cross-connections.

(b) In the event of contamination or pollution of the drinking water system due to a cross-connection on the premises, the local health officer and the City shall be promptly advised by the person responsible for the water system so appropriate measures may be taken to deal with the contamination or pollution.
