The article presents keramzite sand as filling for filter and operating columns of water wells. The research and comparing analysis of keramzite and quartz sand are maintained, friction force caused by contact of column and filling is calculated. Costs for materials are compared as well. It was found that water well equipped with filling of keramzite sand is better suited to overhaul.
