with the water quality objectives set by the Santa Ana Regional Water Quality Control Board for
the use of recycled water in Yucaipa and Calimesa. The reverse osmosis treatment process
enables the District to remove salts and minerals from the recycled water supply which results in
an exceptionally pure quality recycled water source. The non-reclaimable waste produced from
the reverse osmosis system, referred to as brine or reverse osmosis concentrate, must be
conveyed in a pipeline to lower portions of the Santa Ana Watershed for treatment so it does not
degrade fresh water resources throughout the watershed.
In order to utilize the Inland Empire Brineline, the project partners need to purchase and maintain
ownership of two primary components: pipeline capacity and treatment capacity. Sufficient
pipeline capacity is needed to convey the brine solution through the Santa Ana Regional
Interceptor, or Inland Empire Brineline shown in purple above. Sufficient treatment capacity is
also required to provide treatment to the brine solution in treatment facilities owned and operated
by the Orange County Sanitation District.
In 1993 the District purchased our original 0.108 million gallons per day of brineline pipeline
capacity. A second purchase of pipeline capacity was secured in 2006 providing an additional
1.0 million gallons per day for a total of 1.108 million gallons per day of brineline pipeline capacity
in the Inland Empire Brineline.
In 2013, the Yucaipa Valley Water District purchased 0.295 million gallons per day of treatment
and disposal capacity in the Orange County Sanitation District’s facilities.
