Deep Well (Drilled Wells)
Deep Wells (Drilled wells) can get water from a much deeper level by mechanical drilling. Drilled wells with electric pumps are currently used throughout the world, typically in rural or sparsely populated areas. Most shallow well drilling machines are mounted on large trucks, or trailers. Such wells typically range from 20 to 600 feet (6 to 180 meter), but in some areas can go deeper than 3,000 feet (910 meter). Roughly deep wells over 600 feet (180 meters) with purification plant costs approx. $30,000 and up.
