I welcome any help with these facts.
First, The US has 52,000 water systems, serving 90 percent of Americans. Apparently, 39 million people [NO SOURCE] -- the rest -- get their water from private wells.
Second, does anyone have statistics on the number of systems (or better, customers) who pay for their water based on (1) fixed rate (all you can eat), (2) uniform or flat rate, (3) increasing block rates, or (4) decreasing block rates?
Thanks for any help!
