current water treatment methods can turn sewage into cleaner water than most people get out of wells. I know on the cruise I was on last year they told us that they were required to filter their sewage from the boat before they could dump it and it was actually purer than the water we were drinking from the taps, but due to the fact that they didnt have anyway or anybody to test the water reclaimed from the sewage that they couldnt put it back into the supply.
