This is the story of the water we drink: how it is collected, filtered, and pumped into our homes. But what happens to it after it has been through our bodies and flushed down the lavatory? Find out how it is cleaned up with the help of bacteria so we can drink it all over again.
This informative video about an essential modern utility, clean running water from the tap, starts with the water cycle and continues through our water treatment processes: Lots of filtering and flocculation, “the process by which fine particulates are caused to clump together” before they’re removed.
And once water has moved through the house (and our bodies), the short explains how the sewers funnel the waste to a sewage-treatment plant where filtering, separation, and helpful friendly bacteria make it clean again.
