News Summary

The California Public Utilities Commission has greenlit a major desalination project to combat a looming water deficit in the Monterey Peninsula, projected at 815 million gallons per year by 2050. Led by California American Water, the initiative aims to create drought-proof water resources amidst ongoing drought conditions. Despite opposition from local agencies and environmental groups, the unanimous CPUC decision highlights the project’s importance for the region’s economic growth and community water supply. Construction is expected to begin by the end of 2025.

California – The California Public Utilities Commission (CPUC) has approved a significant desalination project aimed at addressing an impending water shortage in the Monterey Peninsula. This decision follows the adoption of Phase 2 Demand and Supply Estimates, projecting a regional water supply deficit of approximately 815 million gallons per year by 2050. The approval, which comes amidst ongoing drought conditions, emphasizes the necessity for new, drought-proof water supply resources in the area.

California American Water, which is spearheading the desalination project, has expressed its commitment to providing safe and reliable water to its customers. Currently, the Monterey Peninsula is under strict limitations on new water connections due to orders from the State Water Resource Control Board, which restricts water pumping from the Carmel River, a historically relied-upon source. This project is part of a larger strategy that includes aquifer storage and recovery and the expansion of the Pure Water Monterey facility, addressing the need for additional water supplies to secure the community’s future.

The desalination plant is expected to break ground by the end of 2025. The CPUC’s decision was supported by three out of the five commissioners, despite opposition from several local water agencies, environmental advocacy groups, and community members. During the public comment session, approximately 165 individuals voiced their opinions, with 28 expressing concerns over the project’s feasibility and the motives behind it. Ultimately, the CPUC concluded with a unanimous decision of 4-0, with one commissioner recused from voting.

Critics argue that the project may be unnecessary, raising questions about the accuracy of California American Water’s water demand estimates. Despite these objections, administrative law judges at the CPUC endorsed the estimates, anticipating a need for 13,732 acre-feet by 2050. Some local opponents have suggested exploring alternative water sources, particularly once the cease-and-desist order is lifted, which may result in surplus water availability.

The Monterey Peninsula has faced challenges due to significant over-pumping from the Carmel River, leading to environmental concerns and regulatory restrictions in recent years. Supporters of the desalination project assert that it is vital for sustaining economic growth, including the ongoing development of affordable housing within the region. Extensive environmental reviews spanning over six years and the recent upholding by the Monterey County Superior Court of Coastal Development Permits for the desalination project have been essential steps in moving the initiative forward. Proponents argue that this project is crucial for meeting both current and future community water needs and aims to complement existing water resources while lessening dependence on inconsistent rainfall for supply.
