The desalter facility would pump and treat poor quality groundwater from a shallow aquifer in the South Las Posas Basin and provide higher quality water to future users. The Project is a key element in the Northern Reach Renewable Water Management Plan which was developed as part of the Calleguas Creek Boron, Chloride, Total Dissolved Solids, and Sulfate Total Maximum Daily Load Compliance Plan. The Project would supplement imported water supplies, remove poor quality groundwater, allow higher quality storm flows to recharge the shallow unconfined groundwater basin, and improve the groundwater quality of the overall basin. Brine produced by the reverse osmosis process would be transported out of the watershed through the Salinity Management Pipeline (SMP), currently being constructed by Calleguas Municipal Water District. The SMP would convey brine from Moorpark to the ocean discharge point at Point Hueneme. The Project would include approximately twenty two extraction wells and a conveyance pipeline from the well field to the desalter facility.
