Sari (Brine) Line
The Santa Ana Regional Interceptor A Quality Solution
Santa Ana Watershed Project Authority
The SARI line, a regional brine line, is designed to convey 30 million gallons per day (MGD) of non-reclaimable wastewater from the upper Santa Ana River basin to the ocean for disposal, after treatment. The non-reclaimable wastewater consists of desalter concentrate and industrial wastewater. Domestic wastewater is also received on a temporary basis. To date over 73 miles of the SARI line have been completed. The most recent extension (23 miles in length), the Temescal Valley Regional Interceptor (TVRI) line (now referred to as Reach V) was completed in 2001.
The Santa Ana Regional Interceptor (SARI) in its current configuration of over 90 miles of pipeline, transports “brine” and wastewater from Orange, Riverside, and San Bernardino Counties to Orange County Sanitation District’s (OCSD’s) Regional Treatment Plant No. 1, or No. 2. Initial segments of the SARI were constructed in 1975, with the most recent segment (Reach V) completed in 2002. |
The SARI is an important regional water quality asset because it prevents water containing salts (also termed “brine”) from being discharged into the Santa Ana River, which would then percolate into Orange County’s groundwater basin. The “brine” contained in the SARI, which is significantly less salty than ocean water, comes mostly from desalter plants operated to remove salt from existing groundwater, making the treated water available for use. One example is the Arlington Desalter which removes salt from water extracted from the Arlington Groundwater Basin and delivers the treated water to Orange County Water District (OCWD) for percolation into Orange County’s groundwater basin. In order to reduce the watershed’s reliance on imported State Project and Colorado River water, to remove salts from the groundwater basins, and to ultimately achieve a “salt balance” in the watershed, a number of additional desalters are under construction, or planned for the near future. For further background information on the existing SARI and salt imbalance in the watershed, see the SARI Planning Study and the Water Resources Plan posted to SAWPA’s website. |
