Say every single one of the 330 million people in America flushes a toilet five times a day, every day of the year.
That’s still less than a cubic mile of water. Lake Mead, by comparison, has a volume of 7 cubic miles. Every American could go back to using outhouses and the water savings wouldn’t even be noticeable.
People are not very good at visualizing this stuff. The volumes involved are hard to grasp.
Or think of it this way: if you personally saved all that water by using an outhouse, it would amount to less than 300 gallons a month. My water bill doesn’t even show usage at a resolution high enough to see those savings. I’m billed per 1,000 gallons.
If the water company doesn’t care enough to track it and charge me for it, it’s noise.
For what it's worth there are other considerations like wastewater processing capacity, especially when it rains
