Pilot project to increase the economic efficiency of surface water pumping stations

Purpose: The most common effects of surface subsidence are flooding and waterlogging of the most depressed areas, and a change in the direction and intensity of surface water runoff. Stopping drainage would result in flooding of depressed areas on the surface and contamination of near-surface aquifers, which are also a source of drinking water. Design/methodology/approach: The research was carried out based on geodetic measurements carried out by surveying services in the vicinity of the analyzed watercourse. From the prepared database of functional scenarios for pumping stations, the optimal variant was selected based on a panel study of experts. Findings: The publication analyses the possibilities of reducing the costs of the functioning system of storm water drainage from drainless basin in the area of an abandoned mine. A technically feasible and economically viable design solution was presented. Research limitations/implications: Due to the limited area of available land, the pumping station modernization project envisages generating electricity only for own needs. When making investment decisions, all investment attractiveness factors indicated in the study should be taken into account. Practical implications: The process of draining drainless basins is energy-intensive. Reducing expenditure on the purchase of electricity will improve the security of energy supplies. The pumping station has some retention, but a longer shutdown time could lead to environmental problems. Removing the damage would require financial outlays and would take many years. Social implications: Planned energy supply security projects may have a positive impact on the local community and economy. The project in question will create new markets related to "green energy". Originality/value: The combination of drainage problems in drainless basin and the use of renewable energy sources to improve power supply security has not been the subject of scientific research so far.
