Topic Overview
The Sacramento Regional County Sanitation District (Regional San), in
collaboration with regional stakeholders, is developing an innovative
program known as Harvest Water. The Program provides an exceptional
opportunity to proactively restore groundwater levels, support
groundwater dependent ecosystems, benefit wildlife habitat, sustain
agricultural lands, and improve regional water supply reliability.
Harvest Water has the potential to provide up to 50,000 acre-feet per
year of tertiary-treated recycled water to irrigate approximately 16,000
acres of agriculture and habitat lands in southern Sacramento County.
The recycled water will be used in-lieu of pumping groundwater. By
providing recycled water to existing agricultural lands that
historically pump groundwater, Harvest Water would reduce withdrawals of
groundwater and allow levels in the Program area to recover, benefitting
groundwater dependent ecosystems and local streamflows. A portion of
stored groundwater could be withdrawn in future dry years to meet the
needs of agricultural users, therefore enhancing water management in the
southern Sacramento region by conjunctively managing surface and
groundwater resources.
The Program also establishes an ecological program that supports existing
conservation efforts in the area. Modeled climate change scenarios under
baseline conditions indicate groundwater levels will continue to
decline. Without the Program in place, the declining groundwater
elevations will severely impair the ecological function of conserved and
restored wetland and riparian habitats. As such, Harvest Water is an
excellent example of how recycled water projects can provide a multitude
of benefits and improve climate change resiliency. The California Water
Commission's Water Storage Investment Program has awarded Harvest Water
$291.8 million in grant funding based on the Program's ecosystem and
water quality benefits.
