When sewer treatment plants discharge their effluent into retention basins for dispersal back into the water supply, in essence your drinking treated toilet water. Hate to break it to you, but many man-made areas for riparian, environmental/wildlife habitats, marshes, and even lakes are made from treated effluent. Ultimately it ends up back into the drinking supply.
Bob,
I believe here in Hawaii (at least on Oahu) the water that is treated is actually released into the Ocean.
...The advanced primary effluent is then discharged through a 13,971-ft long outfall, the diffuser at the end jetting the effluent into the surrounding ocean water at a depth of 240 ft, one of the deepest outfalls in the world. The near-shore part of the outfall is buried in a 15-ft deep trench cut in the ocean floor....
