Footnote:
Apart from using just 2% of traditional irrigation, farmed algae also double their bodyweight and oil content every 24 hours, under optimised conditions. Which are. Long clear plastic pipes and a diet of nutrient-rich recycled water.

Moreover, the water isn't so much consumed as partially drained of the nutrient load. Which is then passed through rotary filters to separate out the harvestable algae and return the water to the system, via activated carbon filters.

The system can easily be, endangered wetlands or new manmade ones. Where mop crops like clumping bamboo turn out a biannual harvest every two years and replace timber in building products etc.

And or industrial hemp.

Papyrus reeds for very fine parchment paper and so on.

Or any other normal fruit or nut crop that can be irrigated via underground tapes and underglass intensive agriculture, so the pristine evaporate can be added to town water.

All of which would hit the bank balances of the powerful water barons and their political lickspittle puppets!?

Further footnote:
If it was considered desirable to lift the pristine evaporate to great heights. So it could turn a turbine or two as it is returned to town water.

Then long clear plastic or glass pipes laid upward on northern slopes will do just that as the water vapour rises as do clouds and via the same principle. And then feed into shaded radiators where the cool breezes condense it back to water.

Yes I know, that's a lot of investment in infrastructure. But none on pumps or energy. And can be collected in purpose-built reservoirs then sent down through turbines, when peak load demands it?
