Is part of the problem here that there just aren't that many rich people? If there are a few people in a district of 100,000 who are using 1000x as much water as a normal household, and those people cut their usage 100%, that's still much less overall savings than convincing the remaining 99,990 people to cut their usage by 20%. Yes, it looks bad that rich people can consume whatever they want and the masses of poor people are the ones that have to conserve, but if this is the reality of the situation then focusing on the rich seems rather petty and spiteful.
