Sewage Pumping Stations

Prior the complete sewage pumping station installation in the designed position, the excavation pit should be arranged - excavation, water level reduction, sheet piling of the excavation walls (if necessary) and concrete slab to which the pump housing is fixed with anchors to prevent the floating up under the groundwater pressure. After fixing the pumping station housing in the designed position, the backfilling of the excavation pit around the pumping station is performed layer-by-layer with compaction by vibrating plate. As the backfilling reaches the level of the sewage pumping station branch pipes, the input and output pipes of the sewage pumping station are connected with sewage system collectors and the sewage pumping station housing with the connected collectors is refilled. Then the pump equipment is installed, internal pipelines are installed, float switches are set, and the pump equipment is connected to the control box. The final stage is commissioning and testing.

To ensure trouble-free operation of the electromechanical equipment of the pumping station, it is necessary to observe systematically the readings of the equipment, check the condition of electrical connections, equipment fixing, proper operation of the earthing system of all equipment, and perform periodic maintenance of the pumping equipment. Care and maintenance of pumping units must be carried out in accordance with the pumping unit manufacturer's instructions. When commissioning pumping units after repairs, if the pump cable has been disconnected from the control box, the direction of the motor rotation of must be checked.
