The subject gives basic information about the problems of groundwater tapping. First of all it is intent on these special problems – projecting in groundwater tapping – basic data for projecting – physical and chemical water properties with respect to well design; principal equipment types for water intake (water tapping) – horizontal, vertical and combined tapping equipment, classification of the wells for groundwater tapping – design of particular parts of wells – filters, construction and types; methods of drilling hydrogeological wells and technical means for their realisation; drilling muds used for water well drilling; sitting of the objects for groundwater tapping; pumping equipment used in hydrogeological research and in groundwater tapping; testing equipment and monitoring wells.
