Gravel filter plant in a plant for the properties of the water supply for a smaller amount of water, such as, for example, for a - or two families house,• with a stationary filtration container (2),• with filter material (6), which in the filtration container (2) receiving, and there of a container foot space (2.4) grows upward,• with a in an upper container bottom (2.3) of the filtration container (2) a valve (12 arranged),• with a into a container head space (2.5) of the filtration container (2) guided and ending at feed line (16.1) for unfiltered water (w),• with a from the container foot space (2.4) and, beginning from the filtration container (2) out of the discharge line (16.2) for filtered water (w''),• with a metering valve (10) for the addition of air and / or qxidationsmittel (o) to the unfiltered water (w) and• with at least one valve for carrying out of an automatic operation of the gravel filter system (1), for the backwashing and filtered to a concentration of the filtration container (2),characterized by the,• that in the upper container bottom (2.3) a central control valve (8) and the metering valve (10) for the addition of air and / or oxidizing agents (o) are arranged,• that the discharge line (16.2) via the central control valve (8) into the container foot space (2.4) is guided and terminates there,• that in the feed line (16.1) or in the discharge line (16.2) a the metering valve (10) associated flow sensor - means (14) is arranged,• a closing - or an open position of the metering valve (10) with the aid of the flow sensor - means (14) is controllable.
