"Desalination is ridiculously expensive" - as long as you are near the ocean, it's pretty cheap. Hyflux[1] on a 25 year DBOO contract will sell you as much water as you want for less than $0.50 per 1000 liters. Combined with even a modicum of water conservation [2], you can get per-capita water use down to around a cost of $0.05/day at a 100 liters of use a day.
