§ 4.16.140. Facilities design.

A.

Off-site Facilities.

1.

Any off-site recycled water distribution facilities required to serve existing or new developments of the property within the District, as determined by the Administrator, shall be provided by the applicant, owner, or customer at their expense, unless the Administrator determines it is a District benefit to construct these capital facilities.

2.

The design of off-site facilities, including the preparation of plans and construction specifications shall be under the responsibility of an engineer registered in the State of California. The design of customer (on-site) facilities that will use recycled water, and preparations of plans and construction specifications, shall be stamped and signed by a State of California Registered Landscape Architect or Civil Engineer, unless otherwise approved by the Administrator.

3.

All off-site and on-site recycled water facilities shall be designed and constructed according to the requirements, conditions, and standards as adopted in the District Standard Specifications to ensure that this system is in full compliance with this ordinance. Recycled water systems, both on-site and off-site, shall be separate and independent of any potable water systems.

4.

Before the Administrator grants final acceptance of any system using recycled water, as-built drawings of the system shall be provided. The installed system shall be tested in accordance with the District Standard Specifications to ensure that the system is in full compliance with these rules and regulations.

5.

Plans and specifications for all recycled water distribution facilities shall be submitted to and approved by the Administrator, and other regulatory agencies, in advance of construction.

6.

The District will assume responsibility for providing recycled water service to the point of connection of such development on transfer, to the District, of the title to all off-site recycled water systems and any necessary easements. All easements shall be in a form acceptable to the Administrator, and not subject to outstanding obligations to relocate such facilities or any deeds of trust, except in instances where such is determined by the Administrator to be in the best interest of the District.

7.

The District and the property owner or developer may enter into a reimbursement agreement for the portions of a recycled water system that are required to be oversized with capacity to supply more recycled water than the property owner or developer requires. The determination to enter into a reimbursement agreement, and the specific items that are the subject of reimbursement, will be made by the District.

B.

On-site Facilities.

1.

The user or the owner of the property shall be responsible for all costs associated with on-site recycled water facilities.

2.

When District Standards and Specifications require a higher quality material, equipment, design or construction method than that required by other governing codes, rules and regulations, the District Standards and Specifications shall take precedence.

3.

Where the premises contain dual or multiple water systems, the exposed portions of pipelines shall be identified at sufficient intervals.

4.

Areas irrigated with recycled water must be kept completely separated from domestic water wells and reservoirs. Recycled water shall not be applied or allowed to migrate to within fifty (50) feet of any well used for domestic supply. No impoundment of recycled water shall be located within hundred (100) feet of any domestic water well, unless it can be demonstrated that special circumstances justify lesser distances to be acceptable.

5.

In areas where recycled water is not immediately available when the use area is ready for construction, and if the District has determined that recycled water will be supplied in the future, on-site facilities shall be designed to use recycled water. Provisions shall be made to allow for connection to the District off-site recycled water facilities, when available. In the interim, potable or other suitable water may be supplied to the on-site facilities through an "interim service connection."

When the switch over from potable water to recycled water is made, the potable water line will be properly physically separated and blind-flanged to protect the domestic supply and avoid any future reconnection. In such cases, besides an initial cross-connection inspection, the District shall conduct appropriate shutdown tests at both water lines prior to the use of recycled water. The report of the inspection and shutdown tests shall be maintained on file and summary of the findings shall be submitted to DHS within two weeks of the beginning of the recycled water use. Shutdown tests shall be performed and repeated as required by DHS.

(a)

Conditions of interim service are:

i.

The District anticipates recycled water will be available to the site within five years of the time interim service is initiated.

ii.

The user or the owner of the property must sign a Recycled Water Use Agreement.

iii.

The user or the owner of the property must agree to perform or pay for all work necessary to remove the interim connection and make connections to the permanent recycled water system at the time the recycled water system is installed.

iv.

An approved backflow prevention device is required on the interim service. The backflow prevention device shall be at the point of connection with the interim supply system and a part of the on-site recycled water facilities.

v.

Future recycled water users will pay for the following:

a.

Cost of constructing and abandoning the interim service and cost of constructing the recycled water service.

b.

Applicable recycled water fees at the time service becomes available.

c.

Applicable interim water rates for the type of water delivered through the interim service.

vi.

When recycled water is available to the site, an inspection of the on-site facilities will be conducted by the Administrator to verify that the facilities are still in compliance with the Recycled Water Use Agreement. Recycled water service shall be provided on verification of compliance. If the facilities are not in compliance, the Administrator shall notify the user to make any necessary corrections.

C.

Miscellaneous.

1.

Adequate means of notification should be provided to inform the public, employees and others that recycled water is being used. Conspicuous signs with appropriate wording that can be clearly read should be placed at adequate intervals around the authorized use area.

2.

Golf courses should print messages on score cards in a different color indicating recycled water is being used. Water hazards containing recycled water should be posted with appropriate signs.

3.

Languages in addition to English should be used on signs where appropriate.
