Evaluate each area that needs water and give them that amount. Each house gets a monthly amount (ten percent more then use) and once gone. They need to buy water on the economy. Water usage would be adjusted and soon everyone will use their monthly allowance. So easy.

People will have to go where the water is. We will be seeing a micro view of what will be an exponentially growing problem. We will deal with climate change the same way that Trump tried to deal with Covid; denial, and the results will be similar.

when i was a boy , mom and i went to new mexico on a trip. i was told by somone that the indins own the water rights by treaty. (somone from there could send me a pm to refute or prove this ) a motto i can remember was , " if you can afford the lawn, can we afford the water ?" do we really need these huge gardens with huge spralling lawns ? every where i look i see non pourous surfaces, compacted soil. storm water runnoff . slow it down , spread it out .
when i was in los angles area in 1976 we were in a drought ( this is a extention of that 20 year drought .) we were on odd ,even days of watering . no washing of cars , except at car washes that recycled water . we took navy baths ,in and out . now la is requesting ppl to take out lawns and put in drought resisitant and fire resistant plans . it can be done . friend of mine ex husbands mom lived in arizona and on a well , she used every bit of it. ps: this notion of water is for fighting , whiskey is for drinkin needs to stop. we all need to pitch in.

in Santa Monica in the 80s was people washing their sidewalks every morning. Thinking haven't they read Cadillac Desert? Don't they know what a broom is?

Meanwhile, have swimming pools been outlawed? Ditto golf courses? Etc etc...

than a lawn being watered regularly. The water in all the swimming pools in California would not irrigate our agricultural industry for one day. Golf courses are usually watered with non-potable water. The number one use for water in California is growing about one third of our nation's food.

Pools. Decorative fountains. Then lawns and car washes. Leaking plumbing. Then drip irrigation. Less water hungry crops like almond trees.

And food waste. And less water hungry beef.

Lots can be done. Like climate chaos/change. *If* people want to start somewhere.

They can also be a water source for emergencies such as fire. Lawns are a waste of water. Most car washes recover, filter and reuse their water, using far less than washing the car in your driveway. Leaking plumbing is certainly a big water waster. Farmers in California have made huge strides in drip irrigation and other water saving techniques. They had to.

Biggest waster of food is restaurants. Talk to anyone who has worked in one. Roughly one third of their food winds up in the dumpster. Beef is pricing itself out of the market, at least in my house. Fish and Poultry are much healthier anyway.

So yeah, it's been "started", at least in California.
