Western Municipal Water District Arlington Desalter Expansion Phase 2 Project

MND - Mitigated Negative Declaration

Document Description
NOTE: Review Per Lead In its ongoing efforts to improve the quality of groundwater in the Arlington Basin, increase the availability of potable water to the WMWD and to better manage groundwater levels in the Arlington Basin, the WMWD is proposing two basic project approaches (construction of extraction wells only or construction of extraction wells and recharge basins). The Arlington Desalter is undergoing expansion of its treatment capacity to accommodate the increased demand for treatment capacity at the plant. The expansion includes an upgrade in the treatment process which will allow the Arlington Desalter to treat additional raw water while reducing the amount of brine wastes generated. Currently, the WMWD has adequate brine capacity in the SARI pipeline and discharges brine wastes to the SARI pipeline for treatment at the OCSD. The WMWD is in the process of improving the treatment efficiency of the Desalter facility. The WMWD forecasts that after the improvements are made to the Desalter facilities and the wells proposed by this project are operational, the Desalter will remain within its allotted discharge capacity in the SARI pipeline and treatment capacity in the OCSD.
