This well is obtained by drilling a layer of water resistant land to get to the underground water supply.
The well is generally fabricated using a 6 inch inner diameter aspiration pipe that is protected by a tube to get maximum watertightness. In some cases you will not find protective tubing if the well was drilled through rock. A metal or plastic tubing is used for the part that is above rock or in softer soil. This well can be as deep as 1000 feet.
