Cities in Arizona and California are built on desert, and thousands of new homes are being built annually.
People often shower twice a day, and washing machines and dishwashers are standard equipment. There do not seem to be restrictions on watering grass lawns, gardens and golf courses.
Of course they have the mighty Colorado - but all this happens in what is basically a desert, where rainfall is minimal and summer heat tremendous. There must be something we can learn from a country which appears to be managing water supplies with considerable skill.
