Investments in the area of hydraulic engineering are gradually being prepared. As regards port projects, 3 large investments in container terminals in Gdańsk, Gdynia and Świnoujście are planned. For the port in Gdańsk, a strategic advisor has already been selected, whereas in Gdynia and Świnoujście proceedings are still in progress to select the investor and the future operator of the deepwater terminal. A total of 4 entities are interested in the investment in Gdynia, whereas the opening of bids for the execution of the port in Świnoujście is to take place in the second quarter of 2021. The total value of investments in sea ports is estimated at over PLN 20 billion. The final version of the Oder Waterway Development Programme, which will include the E30 waterway on the Oder from the Czech border to Świnoujście, should be published this year. In addition, investments are planned in the E40 waterway on the Vistula river from Gdańsk to Warszawa, the Narew and the Bug rivers, and the E70 waterway on the Oder from the Oder-Havel Canal to Kostrzyn, the Vistula-Oder waterway, the Lower Vistula and the Szkarpawa. The estimated cost of investment in the development of water transport infrastructure is over PLN 77 billion. Of the investments in hydrological infrastructure, the flood protection programme, which has received World Bank funding, is the most advanced. Its key investment is the largest flood protection reservoir with a capacity of 185 million cubic metres in Racibórz.
