Project Description:

Recycled Water – The Wilson Creek Basin Water Recharge project will enable the District to
recharge Recycled Water at the Wilson Creek Basin facility.

The Project would provide additional recharge of the Yucaipa groundwater sub basin by surface
application of highly treated recycled water from the Wochholz Regional Water Recycling Facility
(WRWRF) at the Wilson Creek Basins (Basins), as well as surface application of surplus water
from the State Water Project (SWP) delivered via the SWP East Branch Extension. The Yucaipa
sub basin is located within the Upper Santa Ana Valley groundwater basin, and currently serves
as a local source of drinking water that is recharged by natural underflow from upgradient
groundwater sub basins, as well as by deep percolation of precipitation and streambed infiltration.
The Wilson Creek Basins are currently used to recharge SWP water and have a 7,000-acre feet
per year recharge capacity. If SWP water is unavailable, additional diluent may be provided by
applying potable water to the Wilson Creek Basins from the Yucaipa Valley Regional Water
Filtration Facility (YVRWFF), located adjacent to the spreading basins. A new pipeline will be
constructed to convey recycled water from Yucaipa Valley Water District (the District)’s existing
recycled water distribution system to the Wilson Creek Basins, as well as a new booster pump
station and up to two monitoring wells.
