The Chino Desalter 3 Expansion 3 Expansion Project consists of an expansion of groundwater extraction and treatment in the southern portion of the Chino Basin from an existing 27,000 acre-feet annually to approximately 40,000 acre-feet annually. The project consists of installing and operating the following equipment and components; up to six new wells, new pipelines to deliver the raw water to the Chino I and II Desalters; new treatment facilities at the Chino II Desalter to treat the additional raw water; a possible concentrate reduction facility at the Chino II Desalter; up to four pump stations to transfer product water to potable water suppliers; and new pipelines to deliver the product (treated) water to water suppliers. Once installed, this expanded Desalter system will require electricity to operate wells, pump stations and expanded desalter facilities, and a small quantity of reject water may be disposed of through the Santa Ana Regional Interceptor line for treatment in Orange County.
