Raw and Recovered Water for Irrigating Public Agencies
Trinity County Waterworks District #1, Trinity County
Project Abstract
Raw and Recovered Water for Irrigating Public Agencies will create a tie-in to the Trinity County Waterworks District’s raw water pipeline from the Ewing Reservoir, a tie-in for the backwater water into the raw water pipe via a distribution tank, and a conveyance pipeline to the irrigators via metered pipe. The raw and recovered water will provide irrigation water for several public spaces, including schools and County facilities.
Project Goals
- The objective of this project is to relieve the Hayfork water district of having to provide treated water for irrigation uses to the largest public users. Through this alternative, the goal of providing improved Hayfork Creek summer fishery flows can be achieved. The development of this project will also increase the longevity of the treatment plant to provide water for domestic and business use, while reducing diversions from Hayfork Creek.
- Benefits provided by this project would be numerous. Increased summer flows within Hayfork Creek for fisheries will improve habitat conditions for steelhead and possibly coho and spring Chinook downstream. Increased stream flow would be very beneficial during the summer months when peak irrigation use is greatest and water temperatures are highest.
- A desired benefit to the District would be higher carryover capacity for treated water use that would lessen operational costs during peak periods and the make available water to meet the needs for growth within Hayfork without having to make major improvements to the treatment plant.
- The untreated water delivery system will provide additional fire protection water supplies within TCWD#1.
- The project will provide lower cost, untreated irrigation water that assists with the yearly budgets for several struggling County facilities and the Mountain Valley unified School District by providing a long term, stable and cost effective water supply for their athletic fields and student farm projects.
- The project will reclaim/recycle approximately 150,000 gallons of water per day that would otherwise be wasted.
- Implementing the North Coast Regional Water Quality Control Board's Basin Plan in relation to beneficial uses for municipal water and cold water fisheries
- Implement the South Fork Trinity River Sediment TMDL (EPA, 1998).
- Demonstrating the potential for use of reclaimed water and setting up opportunities to develop additional uses by developing this project for water supply reliability, water conservation, and water use efficiency.
