Don't forget about bathroom fixtures as well. Low-flow toilets, shower heads, etc. Billed as "saving water" but when you have to use them 2-3 times as much just because they're fairly ineffective all it does is waste time and consumes the same if not more water.
And when you install those in old European cities, with centuries old sewers designed for a certain flow rate, the result is stagnation and failures.
I know in Germany in the summer some cities have to use tanker trucks with water to flush the sewers in summer to avoid smells.
