The government is preparing a Retention Development Programme to counteract the effects of drought and increase the low water level in rivers. Work on the plan is expected to be completed by 2020. The assumptions for the programme include a total of 1,550 measures for the amount of PLN 14bn.
Double the retention rate
The Retention Development Programme is to run from 2021 to 2027, with a possible extension of three years until 2030. The costs of the drought prevention programme are planned at PLN 14bn.
Within seven years, the level of water retention in Poland is expected to increase by more than half. Currently, approx. 4bn m3 of water, which constitutes about 6.5% of the average annual river outflow volume. After the implementation of the programme, it is to be about 15% of water, informed the Minister of Maritime Economy and Inland Waterways Transport Marek Grobarczyk.
The project involves 94 small and large investments, including 30 retention reservoirs, water steps and drainage of waterways. This will be combined with natural retention and the development of inland navigation.
Multidirectional retention actions
Under the programme, it will be possible to build a Katy-Myscowa reservoir in the Podkarpackie Voivodeship, whose value is estimated at approximately PLN 1bn. It is also planned to build the Tulce tank on the Mecina River (PLN 18.3m), the Wielowies Klasztorna tank on the Prosnie River (over PLN 1bn) and the Maleszow retention tank in the municipality of Kondratowice on the Sleza and Zelowicka Woda streams (PLN 29.3m).
The plans also include activities that will increase lake and trough retention on the Swan Swan Bagno, Ina and Radew waterways in the West Pomeranian Voivodeship. The cost of these activities is PLN 11.7m.
It is also planned to rebuild small retention facilities in order to maintain the biodiversity of water ecosystems. Some dry tanks designed to receive flood waves will also be rebuilt into wet tanks, which store water in the event of flooding and then drain it in the event of drought.
