Harvest Water, California’s largest agricultural water recycling project, will provide reliable, high-quality recycled water to agricultural lands and existing habitats in southern Sacramento County.
When complete, Harvest Water will supply up to 50,000 acre-feet, which is roughly 16 billion gallons, of drought-resistant recycled water each year and bring other lasting benefits to the region.
What to Expect During Construction
The Harvest Water pipelines will be constructed through several different construction packages featuring a new pumping station, 42 miles of new pipeline, and service connections to control delivery of water to the agricultural customers. Construction of the infrastructure needed to make Harvest Water a reality is now underway. Physical construction is scheduled to be completed in 2026 and the system is anticipated to be operational in 2027.
Harvest Water Benefits
Harvest Water will promote natural groundwater recovery, boost sustainable agriculture, and strengthen existing local habitats in southern Sacramento County, where declining groundwater levels in the past have impacted water sustainability and groundwater-dependent ecosystem health. Restoring groundwater levels to historic conditions by irrigating with recycled water in lieu of pumped groundwater will drive these benefits:
Facilitates Groundwater Recovery
Allows for use of recycled water instead of pumped groundwater for irrigation
Raises local groundwater levels by up to 35 feet over 15 years, increasing groundwater in storage by approximately 370,000 acre-feet which is about one-third the capacity of Folsom Lake
Increases regional and state water supply reliability
Boosts Sustainable Agriculture
Delivers up to 50,000 acre-feet per year of reliable recycled water—approximately 16 billion gallons of water—to directly irrigate more than 16,000 acres of agricultural lands
Restores and manages groundwater in partnership with area landowners, farmers, and ranchers
Stabilizes water supply for the region’s farms, ranches, and rural landscapes by providing a reliable, cost-effective long-term water supply
Strengthens Local Habitats
Improves groundwater conditions to sustain over 5,000 acres of riparian and wetland habitats
Enhances habitats for a variety of listed species, including Sandhill crane, Swainson’s hawk, and Giant garter snake
Increases streamflow in the Cosumnes River, supporting a longer migration window for Fall-run Chinook Salmon
Reduces salinity and nutrients in the Sacramento and Delta waterways

Harvest Water is in southern Sacramento County, roughly between Interstate 5 and Highway 99, south of the City of Elk Grove, and north of Twin Cities Road and the Cosumnes River Preserve.
Background
SacSewer is committed to being a leader in environmental stewardship, which is demonstrated in many of our efforts, including the 2,150 acre Bufferlands conservation program. Through our sustainable efforts in resource recovery, we maximize the reuse of treatment process by-products such as biogas (energy), biosolids (nutrients), and the treated water itself—in the form of recycled water. In fact, our landmark recycled water project—Harvest Water—is a critical component to realizing SacSewer’s goal of increasing recycled water delivery in the Sacramento region.
Partners
Funding
The California Water Commission awarded Harvest Water $291.8 million in Proposition 1 grant funding through the Water Storage Investment Program (WSIP) to help make Harvest Water a reality for the Sacramento region. WSIP funding was awarded based on the public benefits the project provided through a rigorous and competitive review process.
Harvest Water has also been awarded a $30 million grant from the U.S. Bureau of Reclamation as part of the Title XVI Water Reclamation and Reuse Program.
Additional funding sources are also being pursued to help cover construction and operational costs.
EcoPlan
Harvest Water is made possible largely through funding from California’s Proposition 1 Water Storage Investment Program, which supports projects that provide public benefits, including ecological ones. This allows Harvest Water to work with interested farmers and ranchers to implement specialized habitat management activities through the Harvest Water EcoPlan.
