Hawthorne adopts 2025 Urban Water Management Plan; consultants say supplies meet mid-century demands

California Water Service (Cal Water/Cowwater) staff presented Hawthorne's draft 2025 Urban Water Management Plan and the attached Water Shortage Contingency Plan, then opened the required public hearing. The plan uses a 25-year planning horizon (to 2050) and models normal, single-dry and multi-dry-year scenarios.

Jake Lamb, a water-resources engineer with Cowwater, summarized supply sources: imported water (West Basin Municipal Water District) accounted for roughly 86% of the city's supply over the past five years; pumped groundwater from the adjudicated West Coast Basin made up about 14%; recycled water serves nonpotable demand. He told council the plan includes demand projections and conservation measures and that supplies are projected to be sufficient under the modeled scenarios. "Supplies available are projected to be sufficient to meet the projected demands over the next 25 years," Lamb said.

Council approved Resolution 8610 to adopt the UWMP and authorized staff to file the documents with the California Department of Water Resources and State Library by the July 1 deadline. Cal Water will post the final plan to its website and accept comments through the short statutory window already noted in the presentation.
