The Brno councillors approved the creation of a retention basin and a green roof

Brno – A subterranean tank for collecting rainwater will be created in Trnkova Park in the Brno district of Líšeň, which will subsequently serve as a source for irrigation for the surrounding area. The installation of the retention tank, which is part of the park's redevelopment and ties into the overall regeneration of the site, was approved today by the city council. They also supported the construction of a green roof in Medlánky for 2.5 million crowns. This was announced in a press release by Deputy Mayor Petr Hladík (KDU-ČSL).

The anticipated costs for the retention tank are 1.1 million. "We estimate the grant at 937,514 crowns, which is 85 percent of the total costs. The Líšeň district will contribute half of the funding, while the other half will be covered by the city of Brno. However, the project costs or financing structure may still change. The volume of the tank will be 20 cubic meters," Hladík stated.

The project also includes internal modifications to the technical room of the adjacent school, where the control elements for the irrigation system will be located, as well as land adjustments and excavation work.

According to Mayor Markéta Vaňková (ODS), efficient management of rainwater is not only ecological but also economical. "Thanks to the retention tank, the municipality will save on park irrigation, especially during dry periods. The district plans to implement the project even if it does not receive the grant, which makes me very happy," Vaňková added.

The councilors also agreed to the creation of a green roof on a building on Jabloňová Street in Medlánky, which serves as a workshop and storage. "This project is another step in our vision of a thrifty and nature-friendly city. We anticipate total expenditures of 2.5 million crowns, with the grant estimated at 2.1 million crowns. The result will, among other benefits, also lead to cost savings, specifically in this case, public resources," Hladík said.

Green roofs cool the interior space and, to a certain extent, their surroundings, prevent heat loss from the building, reduce the amount of airborne dust, and also retain precipitation that would otherwise flow uselessly into the sewer. The roof is expected to be constructed by this autumn.
