If you do not have a lifelong use of a well, then you can drill a shallow well-10-30 meters. The drilling of such a well does not require large financial investments and you can drill it in one day, but you can use it only 10-14 years. Such a well is called sandy, since water pumping is made of sand layer. He is closest to the surface. But it should be borne in mind that such water will most likely have to be filtered from various impurities like sand and clay.
