|SUN CITY, Calif., May 6, 2004
– USFilter has been awarded a $2 million contract to
supply the Eastern Municipal Water District (EMWD) with
equipment for a 4.5-mgd reverse-osmosis (RO) treatment plant
at EMWD’s new Perris Basin Desalination Facility in Sun
City, Calif. The $13.5 million facility, designed
by CH2M HILL, will provide drinking water for 5,500 families
in EMWD’s service area.
The EMWD, located in
the city of Perris, operates the fifth largest water
district in the state of California. Over the
last 14 years, the district’s service area population has
grown significantly from 340,000 to 530,000 residents. This,
coupled with recurring drought, caused the District to
consider alternate drinking water sources.
One of these options
was desalination of brackish groundwater in the Perris
sub-basin. Used as a source of agricultural water
supply for generations, rising salinity has reduced or
eliminated groundwater use in most of the basin. Desalination
not only generates an additional supply of water, but also
provides salinity management for the entire basin.
“Reverse osmosis was
selected as the most cost-effective and operationally
reliable form of treatment for the brackish groundwater
targeted by the District,” says Charlie Bachmann,
assistant general manager, Engineering Branch of the EMWD.
Expected to become
operational in January 2005, the system will treat
groundwater containing up to 7,000 ppm of TDS. The
treatment process will consist of scale inhibitor and acid
feed, cartridge filtration, two 2.25-mgd low-pressure RO
membrane systems, decarbonator for CO2 reduction followed by
pH correction and disinfection of permeate.
The EMWD awarded the RO
system supply contract to USFilter and the installation
portion to CDM (headquarters in Cambridge, Mass.; local
office in Hesperia, Calif.). Under the contract,
USFilter will furnish the system consisting of cartridge
filters, RO pumps, RO skids, decarbonators and a
clean-in-place (CIP) system, to be installed by CDM.
EMWD serves a
555-square mile area from Moreno Valley to Temecula, and
from Hemet and San Jacinto to Good Hope and Mead Valley.
Approximately 530,000 people live and work in this area. In
addition to its own water customers, EMWD supplements water
to eight local water agencies and municipalities that have
their own water departments. EMWD operates five
water reclamation facilities and treats some 39 million
gallons of wastewater daily.
Millions of people and thousands of companies rely on
USFilter every day to help them meet their clean water
needs. Headquartered in Palm Desert, Calif.,
USFilter (www.usfilter.com) is a $1 billion water company
