California's Ocean Desalination: Debunking Myths and Misconceptions

Desalination, or the process of converting seawater into freshwater by removing salt and other minerals, plays a significant role in water management in coastal regions. In California, although a relatively small percentage of the state's water comes from desalination, the debate surrounding its use remains intense. This article aims to clarify some misconceptions and myths surrounding California's ocean desalination efforts.

Current Water Sources in California

Currently, less than 1% of California's water needs are covered by ocean desalination. According to recent data, the largest ocean desalination plant in California is located in Carlsbad, a city not far from where I live. Despite this plant's capacity, the overall contribution of desalination to the state's water supply is minimal.

The Rejection of the Huntington Beach Desalination Plant

In 2022, the California Coastal Commission, which is responsible for approving any new ocean desalination plant, rejected a permit for a proposed plant in Huntington Beach. The decision was made 11 to 0, based on the finding that the plant would be too expensive. However, this rationale raises several questions and challenges conventional logic:

Proponent's Investment and Efforts

The plant's proponent had invested an astounding 100 million dollars over a 20-year period on environmental and engineering studies, economic modeling, and permitting. Despite this significant financial and time investment, the Coastal Commission still deemed the project too costly. This decision can be attributed to several factors:

Absence of Economies of Scale

One of the primary reasons cited by the Coastal Commission is the high cost of water. Interestingly, this high cost is often a result of the complex and stringent permitting processes that can stretch over decades. Additionally, the requirement for extensive and frequent redesigns of the desalination technology only adds to the expense. The Coastal Commission's approach seems to be driving costs up unnecessarily, as it precludes any possibility of achieving economies of scale, which could reduce the per-unit cost of water.

Impact on the Poor and Drought Conditions

The Coastal Commission's statement about the high cost of water affecting poor people is somewhat ironic. In reality, water costs tend to be higher for poor people during droughts when water rationing is implemented. Droughts are now a defining feature of the summer and fall seasons in California, and water scarcity necessitates higher water prices. Therefore, the argument that the desalination plant would harm poor people due to higher water costs is a red herring.

Expert Perspective on Water Resources Management

Having a degree in water resources and water treatment from the University of California, Irvine School of Engineering, I have a deep understanding of the complexities involved in water management. It is frustrating to see the Coastal Commission's inefficiency in driving up costs and hindering the development of feasible water solution projects. The permits for new desalination plants are consistently denied, making it challenging to find lasting solutions to the state's water challenges.

Conclusion and Future Outlook

As California continues to grapple with water scarcity and the effects of climate change, it is crucial to revisit the decision-making processes surrounding desalination. The current system is not only costly but also ineffective. It is time for a more streamlined and efficient approach to water management policies, one that balances environmental concerns with the practical needs of the state's residents. Only then can we hope to address the water challenges that California faces in a sustainable and economically viable manner.
