Director Memorandum 18-140
Date: November 6, 2018
Prepared By: Joseph Zoba, General Manger

Recommendation: That the Board authorize the General Manager to execute a contract
with Geoscience for a sum not to exceed $326,956.
Like most water agencies in the arid southwest, the
Yucaipa Valley Water District is confronted with
increased drinking water demands due to the increased
population and limited local water supplies. The Yucaipa
Valley Water District is somewhat unique given the strict
regulatory requirements that necessitate desalination of
recycled water supplies to protect local groundwater
basins pursuant to the 2004 Regional Water Quality
Control Basin Plan for the Santa Ana Region.
To address a wide range of regional issues, the District
has developed the Yucaipa Valley Regional Water
Supply Renewal Project to accomplish the following
objectives:
REGIONAL BENEFITS:
Provides the Yucaipa Valley with a renewable
water resource that will be a reliable water supply
in the upper Santa Ana Watershed.
Protects and enhances the regional groundwater quality by exporting concentrated salt
brine that would normally accumulate through typical water use.
Reduces the critical overdraft of the Yucaipa, Beaumont, and San Timoteo basins by
reducing the fresh water production from the local groundwater supplies.
Encourages economic and environmental growth of the region by balancing water
demands.
WATERSHED BENEFITS:
Equips the Wochholz Regional Water Recycling Facility with advanced treatment including
reverse osmosis to achieve an advanced, pure, and renewable water resource.
Protects water quality in the lower Santa Ana Watershed by maintaining high quality water
in the upper watershed as the water of the upper basins eventually flows to the
downstream basins.
