I just read the LAPDW urban water management plan. Seawater desalination was excluded from the analysis due to high cost and environmental impacts. Not even considered in their planning. Desal plants are expensive to build, consume a lot of energy and getting rid of the salty concentrate is challenging. Seems like they need the water though.

The plan relies heavily on conservation and recycled water. Recycled water will be mostly used to recharge groundwater supplies that will be withdrawn for treatment to potable standards. The funny thing is that you basically have to build a desalination plant to treat wastewater to make it a suitable potable water source.

Only about 10%of their water supply is local (mostly groundwater). 90% comes from hundreds of miles away (mostly snow melt) through aqueducts and pipelines. 8% of the supply went to non-revenue water including spills, leaks, sludge and water consumed for maintenance of treatment and distribution systems. Another 10% of their supply is consumed by the government.

Australia uses wave energy to pump and desalinate ocean water. Bouys rise and fall with the waves to produce electricity. No external energy required.
