The District has two contracts with the Kern County Water Agency (KCWA) for agricultural water and M & I water from the State Water Project (SWP). These contracts name the District as a Member Unit of the KCWA and provide for a firm entitlement of 19,300 acre feet of water each year (15,000 M&I and 4,300 Ag) from the SWP at 100% allocation. The SWP Reiliability Report forecasts an allocation average of 60%.
The Tehachapi-Cummings County Water District (TCCWD) Imported Water Project begins at Reach 16A, upstream of the Edmonston Pumping Plant on the California Aqueduct. The District’s mainline is within an easement that goes through a portion of the beautiful Tejon Ranch.
The mainline is 31 miles long and varies from 27 to 39 inches in diameter. The nominal operating capacity of the line is up to 9,400 gallons per minute or 21 cubic feet per second. Water is lifted through the mainline a total of 3,425 vertical feet by four pumping plants. Pumping plants 1, 2, and 3 have a lift of 1,025 each feet while pumping plant 4 has a lift of 350 feet.
After the water reaches the District it is stored in Jacobsen Reservoir (also known as Brite Lake) until it is served to agricultural or municipal & industrial users including:
- City of Tehachapi
- Golden Hills Community Services District
- Bear Valley Community Services District
- Stallion Springs Community Services District
- California Department of Corrections and Rehabilitation
The Tehachapi-Cummings County Water District provides imported State water Project Water to agricultural, municipal and industrial and conjunctive use water customers.
In addition, the District provides flood control through the Tehachapi Watershed Project and groundwater managment by acting as the Watermaster for the Brite, Cummings and Tehachapi Basins.
Emissions Reduction Project
In 1994, the TCCWD Emissions Reduction Facilities Corporation was formed to direct the Emissions Reduction Project (ERP). The six million-dollar project was financed by the sale of Certificates of Participation (COP’s). The primary purpose for the ERP was to reduce emissions from the plants in accordance with the regulations of the Air Pollution Control District. The ERP included:
- Construction of an 11 mile natural gas pipeline which makes it possible for TCCWD to transport gas on Mojave Pipeline, thereby allowing competitive bids. The projected savings in fuel cost for this portion of the project was 30%.
- Replacing the existing engines with lean-burn engines and modifying the buildings to house the new engines. The new engines have been successful in cutting emissions, and they are also more fuel efficient.
- Modification of existing telemetry control system which replaced underground cable with a combination of fiber optic cable and spread spectrum microwave.
- Addition of two water storage tanks to triple the storage capacity and allow less cycling at Pump Plant 4.
The District’s Pump Plants are equipped with sixteen multi-stage turbine pumps with right angle gear drives. These pumps are powered by sixteen natural gas fired, internal combustion engines (four engines per plant). Plant 1 is equipped with four Waukesha 5790GL engines; Plants 2 and 3 are each equipped with four Superior 2406G engines; and Plant 4 is equipped with three Superior 1706G engines and one Waukesha F-18.
