Well water is filtered from harmful bacteria and organisms naturally. Because the rainwater or snow soak down into the ground, it is naturally filtered; however, water that is gathered from lakes and rivers may have bacteria and must be treated with chemicals, UV light, or a filtration system. A private well system doesn’t have the problems that water gathered from rivers and lakes has.

For instance in recent years there have been traces of pharmaceutical drugs in the drinking water if gathered from rivers and lakes. This would be rare in well water. The purpose of a “clear well” is to provide chlorine contact time for this disinfection and store water for high demand. A “clear well” is a reservoir for storing water that has been filtered in sufficient quantity, so that there’s enough for the area’s needs.
