More than 70 thousand people and almost 16,000 residential buildings can be flooded if the Upper Vistula basin reaches the flood of the century – according to the just completed analyzes for eight the main tributaries of the river in the south of the country. To reduce the risk of investment is needed in hydrological objects worth more than 2 billion zlotys.

Experts have done analysis of the catchment with the programs necessary investments for the eight major tributaries of the Vistula River in five provinces: the Sola, Skawa, Raba, Nida, Black Staszowska, Dunajca, Wisłoka and San.
Analyses were developed in the framework of the “Programme of flood protection in the upper basin of the Vistula River,” and now form part of the flood risk management plan.
We can not guarantee protection
According to the calculations specialists, from the sources of the Vistula River to the mouth Sanny river, in the case of “water of the century” at risk of flooding will be 16 thousand. residential buildings, 71.5 thous. people, 1.8 thous. public buildings and 1 thousand. 55 industrial facilities. The estimated losses amount to over 4.8 billion zł.

If we could do the planned investments, hydraulic engineering, among others, build the so-called. dry reservoirs and levees, these estimates will be substantially reduced, but not guarantee one hundred percent protection. Still at risk of flooding will be 4.3 thousand. residential buildings, 5 thousand. 362 people, 161 public buildings and 140 industrial plants.
Suggested by experts solution that transfer 1.2 thousand. the most threatened homes in other safe place. As calculated, it would cost it 557 million zł. Another 300 million zł would cost individual protection remaining 3.1 thousand. endangered buildings.
“The price for the reckless building permit”
– This is the price for the reckless, unimaginative issuance of building permits – said Jerzy Miller, Governor of Malopolska.
He stressed that the investment programs for the next tributaries of the Vistula were consulted with the mayors, mayors, sołtysami and residents. – Residents understand that the protection of embankments is not a universal solution. Universal is: “Do not build up where the risk of flooding”. I never thought that within three years will change the approach – added Miller. But – as noted – not everyone is happy with the proposed solutions in investment programs.

According to the calculations by experts in hydraulic structures you need to invest in the basin of the Upper Vistula 2.1 billion zł. You have to build, among others, eight polders, dry reservoirs 73, modernize 63.8 km of embankments and to build 97.5 kilometers of new main rivers and 218.9 km on smaller tributaries.
will schedule
Raise requires 87 bridges, and the analysis indicated a need to increase reserves the flood of 278.3 million m3, for construction of polders, dry reservoirs and increase in the provision flood on three existing vessels (Tresna, Dobczyce, Roznow) of 60.7 million cubic meters. In the coming weeks it is expected to create a schedule that investments must be made in subsequent years from 2016 until 2021.
“The flood protection in the upper basin of the Vistula” was adopted by the government in August 2011. Its implementation was to cost more than 13 billion zł and secure Lubelskie, Lesser Poland, Subcarpathian, Silesian, Świętokrzyskie from the disastrous effects of flooding.
The program was blanked in August last year therefore imposed on Poland by the European Commission the duty uniform way of water management and flood protection. However, the Governor of Malopolska the end of 2015. Coordinate the execution of those tasks that were performed during an extinction program. – The analysis we know exactly what needs to be done on individual sections of rivers and how much it will cost – said Miller.
The investments will be realized in the implementation of the “Plan of flood risk management,” which requires the prior adoption by the Council of Ministers.
