Michelle Kosinski filed a fun feature for NBC's Our Planet series on the latest technology to provide plenty of potable municipal water. On the Pacific coast in California's Orange County, reverse osmosis treats waste water from "toilet to tap as it is unappetizingly called." Do not worry, Kosinski reassured us: "It is not actually straight to your sink." The water goes from sewers through membranes into chemicals through soil filters into underground aquifers before being pumped into the water supply. In Tampa Bay on the Gulf of Mexico 200 miles of desalination filters turn the sea into tapwater in one hour. Kosinski drank a glass just to prove it. It is not so green however. The plant's "carbon footprint is big, $10m in coal-fired electricity per year."
