How do tube wells compare to VillageWater?
Tube wells provide an excellent source of safe water if properly constructed and maintained. Wells must be at least 7.62m (25ft) deep to obtain adequate purification through the soil. They may need to be deeper, depending on the depth of the local water table or aquifer. The depth of the well largely determines the cost. In some areas, the natural aquifers are contaminated with inorganics such as arsenic and fluoride. In addition, if the well is not properly sealed and elevated, or if design flaws or lack of maintenance allow the seepage of ground water into the well bore, the well can leach pathogens into their source water, especially during a rainy season.
