By results of the analysis of results of long-term natural researches of conditions of drinking and household water use of the population infl uence major factors on water supply sources in a countryside are defi ned. These are cattle-breeding and poultry-farming complexes, the enterprises for agricultural products processing, irrigating systems, earthen dams, camp of the summer maintenance of cattle etc. the Priority indicators characterising level of pollution of underground waters, the smell, a transparency, smack, a mineralization, the general rigidity, oxidability, the iron maintenance are. Proceeding from features of pollution of water sources, requirements to the water-purifying installations maintained in a countryside are proved. From the big number of methods of air-conditioning of water methods of clearing with use of the membranes which basic advantages is compactness and high effi ciency of the equipment, and also full absence of additional components in technological processes of water preparation have appeared the most effective. A hygienic assessment of works of installations «Лисскон-101» with water treating on membranes has shown, that they allow to clear effectively underground water in the conditions of rural settlements.
