And I highly doubt water mains never break in Russia.
Not on such supposedly massive scale
Water mains break quite frequently in the Los Angeles area. They are long overdue for replacement but not many seem to get replaced prior to failure. No money apparently but somehow California managed to raise and squander billions of dollars on a "high speed rail" project that few people wanted and even fewer will actually use. We were told to restrict our showers to two minutes, not flush the toilet for number ones, not to water our lawns, not to wash our cars and turn the tap off when brushing your teeth. Priorities eh ?
Once again, you fail to understand. The restrictions you are talking about are due to water supply, not water delivery. The number of people using water goes up, what nature delivers does not. Actually, it's a bit worse than that as the Colorado river water allocation was based on some rather optimistic estimates--the river is not delivering as much as the agreements say it will.
