A. 
Potable Service. Treated water meeting the requirements of the California Safe Drinking Water Act. Can be served for various uses including domestic/residential, commercial, industrial, landscaping and agriculture.
B. 
Nonpotable Service. Water not meeting the requirements of the California Safe Drinking Water Act. Cannot be served for domestic use.
C. 
Recycled Water. Water meeting the definition of recycled water as specified in the California Code of Regulations Title 22, Chapter 3. Appropriate uses are as defined in California Code of Regulations Title 22, Chapter 3, Article 3. Recycled water cannot be served for domestic use.
D. 
Agricultural. This type of water service provides agricultural customers with either potable or nonpotable water, depending upon availability. These customers must have an agricultural operation involving a minimum of five acres of land and meet the definition of "agricultural water use" in Chapter 5.05 WMWDC, General Provisions. This customer classification was discontinued for any customer reclassification of service after December 31, 2008, and new applications are no longer accepted.
(Ord. 392 § 2 (Exh. A), 2020)
The district may provide temporary water service in accordance with district operations department schedules. Temporary service consists of three methods of delivery: fire hydrant meters, jumper connections, and metered service connections. All facilities for temporary water service to the customer's connection shall be operated in accordance with district instructions and regulations. The customer shall be responsible for any loss or damage to the meter or other facilities of the district. The cost of making meter or other water system appurtenances repairs or replacements will be charged to the customer. Unauthorized connections to the water system will be disconnected and a penalty assessed in accordance with WMWDC § 5.15.090, Fraud or abuse. The district may limit the duration of temporary water service.
A. 
Fire Hydrant Meter. A temporary fire hydrant meter may be obtained by making proper application and paying the temporary water service deposit then in effect. A temporary meter must be used (no more than one year) on a designated fire hydrant or water system appurtenance designated by the district. Water supplied from temporary meters is intended only for nonpotable use. A temporary meter connected to the potable water distribution system must be equipped with an approved reduced pressure principle backflow prevention assembly. The customer is responsible for supplying and installing the assembly. The district will have it certified the first time, once it is installed.
Users shall keep the fully executed customer copy of the application for temporary hydrant meter rental at the use site. This copy constitutes permission to operate said temporary service, and must be presented to district personnel upon request. Refer to WMWDC § 5.15.070, Backflow protection and cross-connection control program.
After district operations personnel have opened the hydrant and certified the backflow assembly, the hydrant must remain open. If the hydrant is closed, the backflow test is void and the hydrant will be locked off until the backflow can be recertified. The use of this temporary service is subject to the sole operation of the No. 2 shutoff valve on the backflow assembly. To avoid water hammering, the backflow valve must be operated slowly. Failure to operate this service in this manner may be cause for revocation of temporary water service and financial responsibility for all damages caused by creating a water hammer as observed through telemetry, SCADA or other means. This type of service may require the user to take water at a constant rate and the district may require that the user deliver water to an overhead tank.
When potable water is used to feed a future recycled water site: Prior to the use of recycled water, customers will be required to complete recycled water use training and comply with recycled water use requirements of the California Code of Regulations Title 22, Division 4, Chapter 3, Water Recycling Criteria. Recycled water use is limited to the approved uses listed in the California Code of Regulations, Title 22, Division 4, Chapter 3, Article 3.
B. 
Jumpers. A jumper is a temporary unmetered connection to Western's water distribution system to supply construction water to units in single-family housing tracts. Jumpers are installed in lieu of setting the meters while street improvements are being completed. Jumpers are not available for model homes or custom homes. Jumper connections will be monitored by district staff. All fees, including fees for permanent meter installation and a one-time service charge for each lot fronting the newly constructed water pipeline, must be paid prior to jumper installation. An address sequence list must be submitted when the fees are paid. Jumper connections will be allowed only after the water system has been pressure tested, chlorinated, and successfully tested for lack of bacteria. The permanent meter must be installed prior to landscaping. The developer is liable for all damage, backflow prevention assembly installations, or other requirements or circumstances related to use of this service.
C. 
Metered Service Connections. These are domestic meter connections at permanent locations for use during construction of homes. Upon the developer paying all fees, the district will install the meters. Connections will be allowed only after the water system has been pressure tested, chlorinated, and successfully tested for lack of bacteria. Termination of water service under this title can be accomplished at any time that requirements for metered service connections such as payment are not being satisfied; or after the transfer of ownership of the distribution system pipeline to Western and upon request for service by the first resident of property; or if the house is not to be lived in within 30 days of the end of the construction period, and the final inspection by the building department is verified, then the developer can request to be put on the applicable domestic rate schedule if the billing address is other than the service address.
