FIELD: water supply systems for populated areas using underground water inlets. SUBSTANCE: water supply system for populated areas includes water wells with water elevators installed in them, aerators, sealed tank, pressure transducer and pressure pipe-lines connecting wells with water conduit joined to sealed tank, mixing chambers, pipe-lines feeding water into wells. Mixing chamber and aerator for each water well are mounted in pipe-line feeding water into it and are connected in their turns with the help of pipe-lines carrying controlled valves to proper pressure pipe-line. Sealed tank is equipped with air inlet and outlet controller with float that floats on water surface in tank, with safety valve and air conduit connecting sealed tank with aerator coming in the form of ejector comprising shell, diffuser and confuser. Curvilinear spiral-like conduits are cut in internal surfaces of diffuser and confuser. Hollow elastic ring in which space pulser made of bent bimetal plates is located is joined to end of pipe-line feeding water into water well. Narrowing necks with curvilinear screws in their internal surfaces made of compressed cycloid are linked to space of elastic ring. EFFECT: raised efficiency of water supply thanks to reduced density of fluid. 4 dwg
