Groundwater is one of UK’s most valuable natural resources. Even though most large cities get their water from surface sources such as lakes, rivers, and dams, it is estimated that there is ten times as much fresh water below the land surface than in all the lakes and rivers combined. Groundwater is a far safer water source than surface water because it is protected by soil or rock, and is not so easily contaminated.
A properly constructed water well is the best way to insure that the water you drink is safe and clean. Typically, a borehole used as a well is completed by installing a vertical pipe (casing) and well screen to keep the borehole from collapsing. This also helps prevent surface contaminants from entering the borehole and protects any installed pump from drawing in sand and sediment.
