A. If any waters or wastes are discharged or are proposed to be discharged to the sanitation system, which waters or wastes contain the substances or possess the characteristics enumerated in CVWDC 4.05.340(B), and which in the judgment of the general manager may have a deleterious effect upon the sanitation system, or which otherwise create a hazard to life or constitute a public nuisance, the general manager will in writing:

1. Reject the wastes; or

2. Require pretreatment to an acceptable condition for discharge to the sanitation system; and/or

3. Require control over the quantities and rates of discharge to the sanitation system; and/or

4. Require payment to cover the added cost of handling and treating the waters or wastes not covered by existing taxes or charges under the provisions of these regulations.

B. Discharge from Cooling Towers.

1. General Provisions. Discharges from a cooling tower into the sanitation system may be allowed by the general manager as provided for in this section with payment to cover the added cost of handling and treating said discharge(s), if a permit is first obtained from CVWD.

2. Permit. A written application for a permit to discharge water or wastes from a cooling tower into the sanitation system shall be made and signed by each applicant, on a form supplied by CVWD. This permit application shall include an evaluation of costs and benefits associated with using alternative methods to dispose or reclaim discharges from the cooling tower(s). Applications deemed complete will be considered by the general manager and a permit shall be issued when it is determined, in the opinion of the general manager, that a discharge into the sanitation system is the only reasonable method to dispose or reclaim discharges from the cooling tower(s). Site conditions, costs, feasibility, permit conditions and characteristics of the discharge shall be considered when determining if a cooling tower discharge into the sanitation system is reasonable. Incomplete applications shall be returned to the applicant within 30 days.

A nonrefundable application fee as set forth in Appendix A of this chapter shall be submitted with the application.

3. Permittee Responsibilities – Domestic Water. The permittee shall comply with the permit conditions and the following requirements in accordance with CVWD’s regulations governing domestic water service:

a. Installations.

i. New Installation. Provide at permittee’s sole cost and expense a separate service connection and domestic water meter determined by CVWD to measure the amount of water supplied to the cooling tower. Permittee shall pay to the CVWD the cost for the water meter installation, service connection charge, and backflow device as determined by the CVWD based on the cooling tower demand. Payment shall be made within 30 days of receipt of invoice from CVWD.

ii. Existing Facility. If the cooling tower is located at an existing facility, the permittee shall be required to equip the cooling tower with a CVWD approved sub-metering device on the intake side immediately prior to entering the cooling tower. Installation of a CVWD approved meter device will be required on the discharge side of the cooling tower.

iii. Private Water Source. If the cooling tower is served by a private water supply source, no meter will be required on the intake side but the customer is subject to CVWD’s groundwater replenishment assessment charge (RAC) program specified in Cal. Water Code §§ 31630 through 31639.

b. Amounts.

i. Pay to the CVWD the applicable monthly service charge and domestic water consumptive rate for the service connection supplying water to the cooling tower. A permittee using a private water supply for the cooling tower(s) is exempt from this provision but is subject to CVWD’s RAC program.

ii. Pay to CVWD the building unit charge (BUC) component of the water system backup facilities charges (WSBFC) related to the provision of domestic water service to the cooling tower. The BUC will be determined by the formula as set forth in Table A-3, and shall be paid within 30 days of receipt of invoice from CVWD. A permittee using a private water supply for the cooling tower(s) is exempt from this provision but is subject to CVWD’s RAC program.

4. Permittee Responsibilities – Sanitation. The permittee shall comply with the permit conditions and the following requirements in accordance with these regulations:

a. Pay to CVWD the sanitation capacity charge (SCC) for the proposed cooling tower discharge as set forth in Table A-2, Charge Number A-2.2. The initial SCC shall be paid within 30 days of receipt of invoice from CVWD. If it is determined the operation of the cooling tower places an additional demand on the sanitation system, an additional SCC will be assessed to cover the increased capacity in accordance with CVWDC 4.05.130(F). Any additional SCC for increased capacity shall be assessed at the prevailing rate and shall be due within 30 days of receipt of invoice from CVWD. Failure to pay the additional SCC within 30 days may result in discontinuance of service to the cooling tower.

b. Pay to CVWD the commercial consumptive charge for sanitation service provided to the cooling tower.

c. Install a wastewater sampling port approved by CVWD on the cooling tower discharge facility prior to connection to the sanitation system at a location approved by CVWD.

d. Install a water-measuring device approved by CVWD and which is capable of accurately measuring and registering the accumulated amount of water discharged from the cooling tower(s) into the sanitation system.

e. Perform pretreatment in accordance with CVWDC 4.05.360 or discontinue discharge in response to state or federal discharge regulations if notified in writing by CVWD.
