IRVINE, CA, March 12, 2007 - RBF Consulting (RBF) was recently selected by the Consulting Engineers and Land Surveyors of California (CELSOC) to receive an Engineering Excellence Merit Award in CELSOC's 2007 Engineering Excellence Award competition, for the Chino I Desalter Expansion and the Chino II Desalter Project. The projects associated with this award have been engineered to improve water quality, enhancing the sustainability of the environment in the region.

The Chino Basin is one of the largest groundwater basins in southern California, with approximately 5,000,000 acre-feet of water in the Basin and an unused storage capacity of approximately 1,000,000 acre-feet. This Basin is an integral part of California's statewide water supply system and is one of the region's most reliable water supply sources.

Although the overall groundwater quality in the Chino Basin is good, certain areas of the basin have experienced a decline in groundwater quality. The land overlying areas of measured groundwater quality decline have historically been used for agriculture and dairy waste disposal. This has resulted in a measured increase in the concentration of Total Dissolved Solids (TDS) and nitrate in the groundwater over time.

The Chino I Desalter Expansion and Chino II Desalter Project was implemented by the Chino Basin Desalter Authority (CDA), and overseen by the Chino Basin Watermaster, to treat this degraded groundwater to a potable water quality level and make it available to local cities and water agencies.

The Chino Basin Desalter Authority (CDA) hired RBF to design an expansion of the existing Chino I Desalter and to create a second desalter, Chino II. The new water treatment plant and expansion design utilizes a parallel reverse osmosis treatment system and an ion exchange treatment system to treat groundwater from local wells high in total dissolved solids (TDS) and nitrate.

The RBF team designed 11 new wells to increase the system's groundwater pumping capacity, along with additional piping systems, to deliver the water to the Chino I and Chino II Desalters.

Additionally, the RBF team designed multiple water distribution systems, including three remote pump stations and over 20 miles of pipeline, to deliver the treated water. RBF also assisted with preparation of environmental reports and permitting with multiple county and city agencies, for multiple project sites distributed over a 10-miles radius.

The expansion of the Chino I Desalter and the creation of the Chino II Desalter increased the CDA's water delivery capability to over 15 million gallons each day. This potable water is delivered to six cities and water agencies, including the cities of Chino Hils, Chino, Norco and Ontario, as well as the Jurupa Community Services District (JCSD) and the Santa Ana River Water Company (SARWC). Creation of this new water supply meets one the Watermaster's primary goals: promoting the treatment and beneficial use of the Basin's degraded groundwater, thus alleviating the area's dependency on imported supplies.
