  • Cost is absolutely relevant. Resources are limited. As i have said the wasteful use by industry and agriculture needs to stop. I don’t understand why you are arguing against that and then claim that cost wouldn’t be relevant. Unless you want your taxes to be ramped up so some private business can waste subsidized water and make profits off it.

    The solutions are reducing water usage by using more efficient processes or shutting down wasteful industries. Crops need to be switched to less water consuming crops. Meat consumption and animal farming need to be reduced. Natural structures that help retain water need to be reestablished. Fields need to be downsized with hedges in between to protect against winds eroding and drying out the soil.

    These are the choices we need to make as society. Not throwing even more resources at a wasteful system that has no right to remain wasteful.

    Typically, prices can range from $0.50 to $3.00 per cubic meter. As a comparison, traditional freshwater sources may cost significantly less—often between $0.10 and $0.50 per cubic meter in many regions.

    So you run up the water costs by factor 5. But it only starts there. While the lower end of the basin is close to the Gulf of California, the upper end is some 800 miles away from the sea. Also the upper basin is at an elevation of about 1,500 m.

    So for every cubic meter you get up there you need at least 4 kWh of energy purely to cover the elevation. more realistically you are looking at double that amount as you also need to cover the distance.

    Furthermore you need to build the appropriate pipes and pumping stations. Those need to be kept up and manned, further driving the costs up.

    So you end up with maybe $5-10 per cubic meter of water.
