Recovery of waste water treatment plant infrastructure after flood in Tarnobrzeg
In May and June 2010 waste water treatment plant as well as sanitary sewerage system within five housing estates in Tarnobrzeg were flooded by a wave which was even 2 meters high in places. The flood destroyed buildings at the waste water treatment plant as well as the facilities of mechanical and biological waste water treatment process and caused serious contamination of sewerage system pipelines. In spring 2010, when flooding wave reached Tarnobrzeg, it was not even one year after we had completed investment tasks within the same waste water treatment plant. Sewerage system in flooded housing estates of Wielowieś, Sielec, Sobów, Zakrzów and Dzików was handed over for use only in 2008.
The investment included i.a. modernization of the main pumping station and the biological part of the plant. Within the contract we also modernized grit chamber and temporary sludge storage yard. Moreover, we reconstructed the plant’s laboratory and purchased additional equipment. We also realized the following facilities: storm overflow on the combined sewer, storm rain water pre-treatment facilities and storm rain water pumping station.
