San Diego Carlsbad Desalination Plant may sell water to Arizona, Nevada, or Utah 2026-04-17

An old seawater desalination plant in California wants to make a deal with Nevada, Arizona, or Utah to replace water no longer coming from the Colorado River.

That seems relevant to the Suwannee River Basin’s diminishing Floridan Aquifer water supply. Jacksonville has the Atlantic Ocean next door. Let it desalinate and stop pumping so much groundwater.

Also, if western states can do this, so can Jacksonville:

In addition to desalination, some states are considering recycling wastewater. In 2021, Arizona and Nevada each invested $6 million in a water recycling initiative that is in the final stages. The project, Pure Water Southern California, could eventually convert enough sewage into purified drinking water to supply 500,000 homes.

Both seawater desalination and potable reuse make much more sense than the JEA, SJRWMD, and SRWMD plan to pipe treated Jacksonville wastewater 60+ miles west into the Suwannee Basin. For more about Water First North Florida (WFNF), see:

San Diego’s Carlsbad Desalination Plant opened in 2015, so it’s more than a decade old. It cost about a billion dollars and produces about 50 million gallons a day (mgd) of drinking water.

Scott Dance, The New York Times, April 17, 2026, Western States Need Water. San Diego Has Extra. Will They Make A Deal?
San Diego County is shopping a surplus of desalinated seawater to Western states that are facing increasingly urgent drought and short supplies.

As most Western communities expect to grapple with water shortages this summer and fall, one is looking to share its unlikely surplus. Continue reading
