The parliamentary committee of the maritime economy and the inland sailing revealed the revitalisation plans for Żuławy Wiślane (Vistula Delta Fens), and announced the third stage of the project, which is to end by 2030 . The costs have been estimated at PLN 650m.
The first stage of the flood protection programme for Żuławy Wiślane was completed in 2015., whereas the undergoing second stage should be completed in 2022. The European Union declared to cover 85% of the costs.
In the second stage, in order to construct the anti-ice protection, 19 groynes have been built on the Vistula River. Currently, the reconstruction of the Przewalina barrage is under way, as well as the storm gate on the Tuga river, of which the latter is estimated to cost PLN 33m. The aim of this investment is to protect the town Nowy Dwór Gdański against the backwater flood. The completion of this project is expected in May, 2022.
It is worth noting that, according to the Polish Water National Water Management, 28% of Żuławy Wiślane is below sea level, which requires mechanical draining when the water spills out. When there’s a flood, mechanical pumping must be used on almost the entire area (70%) of Żuławy, since only 30% of this area can be drained by gravity. Hence the need to properly maintain 118 pumping stations.
The deputy president of the National Water Management Authority, Krzysztof Woś, confirmed the start of the third and final stage of the project. The costs are estimated around PLN 650m. According to the plan, the project will be completed by 2030.
