refusing to even consider solutions such as desal plants.

That's not really true; improved stormwater capture, potable reuse, and fixing leaking infrastructure are far more economical & environmentally friendly options being planned or undertaken. MWD put out a proposal last year for a billion dollar potable reuse plant and the SWRCB put out a draft report for regulation of direct potable reuse out last month.

Desalination plants are really an option of last resort given their cost, environmental impact, and capacity. The Carlsbad desalination plant cost $1 billion, runs their RO membranes at 800 PSI, produces 50 MGD, and is ~ $2,000 per acre-foot of water. Whereas OC's GWRS(indirect potable reuse) cost ~$623 million after an initial expansion last year, runs their RO membranes at 150 PSI, produces 100 MGD, and is ~ $476(~$850 before subsidies) per acre-foot.
