    Abstrct. During the commissioning of a new sewage pumping station at an industrial enterprise, the operation service encountered the problem of heavy silting-up of the station storage tank with sand coming from the rain network of the enterprise. Concentration of sand exceeded permissible for the main pumps, which leads to rapid wear of the impeller and the internal cavities of the unit, as well as to abrasion of the pressure pipeline. During the start-up and commissioning of the pumping station, the station storage tank was filled with water from the network and then its complete pumping out by the pumps was performed. After that, in the tank, at the maintenance site, the bottom surfaces, the sump pit and pumps were visually examined. To solve this problem, a guide partition was proposed inside the tank and the placement of a sand pump intercepting the flow of sand-pulp when water moves to the main pumps. Using mathematical modeling of the pumping station tank, two variants, with and without a partition, were investigated. As simulation results, the distribution fields of the volume fraction of the sand-pulp at the bottom and in the sump pit of the storage tank were obtained. The presence of a partition made it possible to exclude the accumulation of sand in the tank and its entry into the pumping pit with a high concentration and redirect the flow to the pumps from the end side of the pit, where a separate section was allocated for the sand pump. Thus, the movement of water and sand was intercepted by a sand pump before approaching the main units. This solution made it possible to protect pumps with minimal costs in a short time.
