Workshop Memorandum 16-005
Date: January 12, 2016
Subject: Overview of a Draft Recycled Water Agreement Between Yucaipa
Valley Water District and Western Heights Mutual Water Company
The Yucaipa Valley Water District and the Western Heights Mutual Water Company have been
working together to manage our limited local water resources with the development of the
following two specific programs.
Immediate Aquifer Recharge (In Lieu Recharge)
The Yucaipa Valley Water District and the Western Heights Mutual Water Company have
recognized the value in using imported water resources as a method to immediately replenish our
groundwater basins with the use of Immediate Aquifer Recharge, commonly referred to as in-lieu
recharge. By resting the production from local groundwater sources and instead using highly
treated surface water supplies from the State Water Project and the Yucaipa Valley Regional
Water Filtration Facility, the local drinking water supplies in the ground are able to be saved for
future use. The use of the Immediate Aquifer Recharge technique protects water quality and uses
existing infrastructure instead of constructing groundwater recharge facilities which are typically
land-intensive and do not generally function well based on the geology of the Yucaipa Valley.
Since 2008, the Western Heights Mutual Water Company has purchased and reduced pumping
in their service area by 2,233 acre feet. This was accomplished by purchasing drinking water
from the Yucaipa Valley Water District.
