Harvest Water

Harvest Water

Recycled Water for Crop Irrigation, Groundwater Restoration, Habitat Protection, and Regional Sustainability

Overview

Regional San, in collaboration with regional stakeholders, is developing Harvest Water (formerly called the South County Ag Program). Harvest Water will offer multiple benefits, including providing a safe and reliable supply of tertiary-treated water for agricultural uses, reducing groundwater pumping, supporting habitat protection efforts, and providing near-term benefits to the Sacramento-San Joaquin Delta.

Harvest Water is an exceptional opportunity to proactively restore and manage groundwater, while improving stream flows in the lower Cosumnes River, enhancing riparian habitats and wetlands, sustaining prime agricultural lands, and improving regional water supply reliability. Harvest Water is being developed by Regional San and has the potential to deliver up to 50,000 acre-feet per year (AFY) of drought-resistant recycled water to irrigate more than 16,000 acres of permanent agriculture and habitat conservation lands near the Cosumnes River and Stone Lakes Wildlife Refuge. Essentially, this recycled water would be used in-lieu of pumping groundwater. Additionally, Harvest Water proposes to implement wintertime irrigation and wildlife-friendly recharge basins in the project area where the soils are suitable, to provide further groundwater recharge.

The California Water Commission announced that Regional San will receive up to $287.5 million in Proposition 1 grant funding through the Water Storage Investment Program (WSIP) to help make Harvest Water a reality for the Sacramento region. The WSIP funding was awarded based on the public benefits expected as a result of Harvest Water.

Next steps include continuing planning efforts with local farmers and beginning preliminary designs for transmission and distribution systems to convey recycled water from the Sacramento Regional Wastewater Treatment Plant near Elk Grove to agricultural lands in southern Sacramento county.

Costs and Funding

The costs to implement Harvest Water are currently estimated at approximately $444.2 million, encompassing planning, design, and capital costs. The California Water Commission recently announced that Regional San will receive up to $287.5 million in Proposition 1 grant funding through the Water Storage Investment Program.

Benefits

Harvest Water offers numerous benefits:

  • Increases regional and state water supply reliability through groundwater storage and conjunctive use
  • Provides up to 50,000 acre feet per year of recycled water to irrigate more than 16,000 acres of agricultural lands
  • Improves water quality by restoring groundwater levels and increasing in-stream flows in the Cosumnes River
  • Restores depleted groundwater levels up to 35 feet within 15 years and helps advance the goal of basin sustainability under the Sustainable Groundwater Management Act (SGMA)
  • Increases volume of groundwater in storage by approximately 245,000 acre-feet within 10 years, and approximately 450,000 acre-feet in 40 years
  • Supports and increases riparian and wetland habitat on over 5,000 acres
  • Supports a variety of threatened species, such as Swainson’s Hawk, Sandhill Cranes and Giant Garter Snake
  • Increases frequency of Cosumnes River instream flows to support fall-run Chinook Salmon
  • Supports the State and U.S. Bureau of Reclamation goals for increased use of recycled water
  • Provides reliable agricultural water supplies and drought resiliency
