Weaverville Sanitary District Water Reclamation
Weaverville Sanitary District, Trinity County
Project Abstract
The Weaverville Sanitary District (WSD) Water Reclamation will recycle wastewater for industrial uses while reducing water diversion from Weaver Creek, a Coho salmon stream. It includes a feasibility and design study for extending recycled water for future irrigation uses. The component includes installation of a tank or pond and fencing on Weaverville Sanitary District (WSD) property; and installation of water main, valves and meters from the storage tank or pond to deliver the water to users.
Project Goals
- Supporting and improving the local and regional water supply reliability by reducing the diversion of surface water from Weaver Creek for non-consumptive uses and replacing water used for non-consumptive uses with reclaimed water from the WSD wastewater treatment plant.
- Reducing late summer mortality to fish while providing water purchasers with a reliable and less expensive water (compared to purchasing treated drinking water) source.
- Increasing the summer water flow in Weaver Creek, ultimately benefiting the State and Federally listed coho salmon and other fisheries.
- Contributing expeditiously and measurably to the long-term attainment and maintenance of water quality standards by inducing higher summer flows, lower water temperatures, and better biological conditions in Weaver Creek.
- Reducing the growing demand on the Weaverville Community Services Districts treated water supplies.
- Providing economic benefits to the reclaimed water users by providing reliable water (compared to summer flow levels in the creeks) at a lower price compared to purchasing treated water.
- 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.
- Implement the North Coast Regional Water Quality Control Board's Basin Plan specifically in relation to beneficial uses for municipal water, cold water fisheries and sediment.
- Implement watershed indicators identified in Table 3.3: “Sediment Indicators and Targets” of the Trinity River Sediment TMDL (EPA, 2001). The work will minimize sediment accumulation in Weaver Creek by providing increased instream flows that would otherwise be diverted for non-potable uses.
- Implement CA Coho Recovery Strategy:
- C RW-SF-03: “Plan water supply development and growth that are not harmful to coho”
- C RW-SF-04: “Increase agency coordination in planning water supply development and growth that are not harmful to coho salmon habitat”
- C RW-SF-05: “Fund planning and education to accomplish water supply development and growth that is not harmful to coho salmon habitat”
- E RW-WT-01: “Identify actions to maintain and restore water temperatures to meet habitat requirements for coho salmon in specific streams”
- D RW-WT-02: “Implement actions to maintain and restore water temperatures to meet habitat requirements for coho salmon in specific streams.”
