I think that it should be mandatory that people install rain water tanks. They have been used here in Australia for years in the country areas and it is usually the only source of water for many places. However it has never been compulsory in the cities and it is time it was. We should all be responsible for collecting at least some of our own water as well as how we use it. Sadly that is not the case because for many nations it is simply a matter of turning on the tap and water comes out.
