- Great importance of land reclamation pumping stations in flood protection makes that operation and maintenance this kind of objects in the most cases is a priority. However, due to the significant resources allocated each year for maintenance a full technical efficiency of pumping stations, writers together with the Department of Drainage and Water Administration in Poznan, Regional Department in Leszno (WZMIUW, RO Leszno), the efforts to assess the possibility of improving the effectiveness of these devices were taken. The study was conducted in 2010–2012, when the 11 from among 12 existing pumping station made a complete renovation, including replacing all pumps, power supply and control system. In accordance with the strategy of the Polish Energy Policy we are obligated until 2030 to reduce energy consumption and increase energy yield of all production processes and supply about 15%. Therefore, the authors' intention was a series of measures seeking to optimize work of the existing pumping stations. In this case, the results of retrofitting achievement was compared by the use of index of economic improvement investments (“ee”). In this way, the present results of carried investment was determined. In calculations the model Life Cycle Cost (LCC) developed jointly by Europump and Hydraulic Institute were taken advantage. This model allows to determine the actual effects of the activities carried out throughout the whole life of pumping system (20 years), differentiating and comparing the results. Analyses were performed with respect to the proposed classification and distribution this objects on leeve’s, reservoir’s and channel’s pumping station. According to research, electricity costs account for 40% of the total expenditures carried by WZMIUW, RO Leszno. As a result of modernization the costs of electricity in total operating costs was reduced by 6%. The analysis conducted for land reclamation pumping stations point to a need for more detailed control of these facilities, including the introduction of the current monitoring continuous recording of rainfall and water level control inlet and the water level in the receiver. Obtained information in this way (with a certain advance) would allow to conduct a more optimal management of water in the catchment area of the pumping station, and thus on their a more efficient operation.
