Never underestimate maintenance costs. The traditional urinals have at least the advantage of self-maintenance. You flush them - they clean-up. If you don't flush, someone eventually will. You don't need someone to look them over or replace the liquid sealant for at least three reasons I can think of right now. It's similar to what you get when you replace intersection lights with LED to save _electricity_. They don't get hot. In the winter they get covered with ice and snow enough to not see them. You then go and clean them yourself and realize that what you saved on electricity doesn't even match the cost of gas and labor you used. Or you don't clean them and you have one or more collisions and you're still no better. How much water you say you save? It is peanuts compared to the water on the toilets...
