en.Wedoany.com Reported - California American Water's Monterey Peninsula Seawater Desalination Project has achieved a key milestone, as the California State Lands Commission (SLC) has voted to approve the company's lease of state-owned land for the construction of certain project facilities.

The approved lease application involves the construction and use of four new underground slant wells, as well as the conversion of an existing underground slant well for use by the proposed desalination plant. During the three-year application review process, SLC staff extensively gathered community input through environmental justice outreach, community outreach, and tribal consultation.

Sarah Leeper, President of California American Water, stated that this approval is critical to providing a reliable, drought-resistant water supply for the Monterey Peninsula. The plan aims to reduce dependence on the Carmel River and create conditions for sustainable growth. The proposed desalination plant is part of the three-pronged Monterey Peninsula Water Supply Project (MPWSP), designed to restore regional water supply, address drought, and support long-term water reliability.

To protect water quality and minimize environmental impact, the facility will utilize underground slant well technology. These wells are drilled diagonally from land beneath the seabed, using natural filtration to draw in seawater or brackish groundwater. Compared to open ocean intakes, slant wells reduce harm to marine life and are less susceptible to waves, storms, and surface contamination.

According to the California Public Utilities Commission's confirmation last year, the Monterey Peninsula will face an annual water supply shortfall of 815 million gallons by 2050. This projected deficit underscores the critical nature of this approval. California American Water stated it remains committed to providing a long-term, drought-resistant water supply for the local community.
