Unit Conversion to AF
DWR NOTES: Units of measure (AF, CCF, MG) MUST remain consistent with units reported in Submittal Table 2-3. This table identifies the unit of measure selected in Submittal Table 2-3. The unit conversion to Acre Feet addresses the Water Code's requirement that this value be provided in acre-feet. NOTES: Estimates are based on comparisons between historic and expected conversion projects. Over the past 5 years, IRWD has seen the rate of increases in recycled water use decline due to limited opportunities for new conversion projects and recycled water system hydraulic limitations. Values are all in AF.
6.6 Desalinated Water and Opportunities
Law
10631(g) Describe the opportunities for development of desalinated water, including, but not limited to, ocean water, brackish water, and groundwater as a long-term supply.
In Orange County, locally desalinated water from brackish and ocean water sources have been evaluated as potential alternative water supplies. OCWD has evaluated a formerly proposed 50 mgd seawater desalination facility at a site in Huntington Beach. The formerly proposed desalination facility would have been constructed and operated by Poseidon Resources, a private company. While the project was being considered by OCWD, IRWD made the determination that it had no need for water from the proposed desalination project. In 2022, the California Coastal Commission denied the proposed project’s Coastal Development Permit, effectively stopping the proposed project. Currently, South Coast Water District is in the planning and design phase of its proposed Doheny Ocean Desalination Project. The proposed project could potentially deliver water to adjacent cities and water districts. IRWD is not aware of any additional desalination facility proposals in the area at this time.
