Monterey Peninsula, August 16, 2025
News Summary
The California Public Utilities Commission has approved the Monterey Peninsula Water Supply Project to address a projected water supply deficit of 815 million gallons per year by 2050. This decision highlights the urgent need for drought-proof water resources in the Monterey Peninsula. Despite some opposition from local water agencies, the project aims to provide a sustainable water supply while reducing dependency on the over-extracted Carmel River. Construction is expected to begin by the end of 2025.
California Approves Desalination Project to Combat Water Shortage
The California Public Utilities Commission (CPUC) has approved the Monterey Peninsula Water Supply Project aimed at addressing a projected water supply deficit of approximately 815 million gallons per year by 2050. This decision emphasizes a pressing need for drought-proof water supply resources in the region.
Currently, the Monterey Peninsula is under restrictions that prevent the addition of new water connections due to mandates from the State Water Resource Control Board, which limits pumping from the Carmel River. In response, the desalination project is part of California American Water’s comprehensive strategy to secure sustainable water sources, alongside initiatives for aquifer storage and the expansion of the Pure Water Monterey facility.
Project Details
California American Water has plans to commence construction of the desalination plant by the end of 2025. The project was supported by three out of five CPUC commissioners, despite encountering opposition from several local water agencies and advocacy groups concerned about the potential implications of the project.
During the public comment session held prior to the decision, approximately 165 individuals spoke, with 28 opposing the project. Their concerns focused on the accuracy of data presented by California American Water regarding water demand. Ultimately, the CPUC reached a unanimous 4-0 decision after administrative law judges supported the demand estimates projecting a need of 13,732 acre-feet by 2050.
Community Needs and Concerns
Supporters of the desalination project argue that it is crucial for sustaining economic growth and enabling the development of affordable housing in the Monterey Peninsula. However, critics question the necessity of the project, advocating for alternative solutions, including surplus water expected to become available once current cease-and-desist orders are lifted.
The Monterey Peninsula has historically relied on the Carmel River for most of its water supply. However, over-extraction has led to significant environmental impacts, prompting regulatory measures to govern water use. In light of these challenges, the desalination project is seen by some as a necessary step to ensure long-term water security in the region.
Regulatory and Legal Framework
Environmental reviews and public commentary on the desalination project have extended over six years, with numerous stages of consideration by regulatory bodies. Recently, the Monterey County Superior Court upheld the California Coastal Commission’s approval of necessary coastal development permits, marking a significant milestone in the project’s progress.
Implications for the Future
The decision by the CPUC signals a critical moment for the Monterey Peninsula, where the demand for reliable water supply continues to grow amid changing climate patterns and ongoing drought conditions. The desalination project is positioned to complement existing water resources and reduce dependency on inconsistent rainfall as a water source.
