SUBSTANCE: invention relates to sewage plants. The plant comprises a reservoir, which at least in one wall of the reservoir has at least one inlet hole. The inlet hole is made circular, and in the inlet hole there is a circular flange orifice, which has a nozzle for pipe reception. The nozzle is arranged with eccentricity relative to the centre of the flange orifice and on the outer side of the reservoir ends substantially aflush with the plane set by the outer perimeter of the flange orifice.
