Circular water management in Liberec zoo and Barcelona zoo





...

Water is one of the most precious resources for life and we believe that its sustainable use is crucial for the preservation of our planet and the lives of humans, plants and animals.

That is why we have teamed up with zoo Liberec and zoo Barcelona to create a new "circular economy" system for water management.





...

The main objective

Our main goal is to move from the traditional linear model of water consumption to the innovative FIT4USE concept for water circulation. This method will allow the repeated use of less polluted water instead of its one-time use. This "circulation of water" will allow Zoo Liberec and Zoo Barcelona to use water repeatedly. It will bring operational savings, lower load on sewage systems and multiple synergies leading to better use of water and energy.

1. Reduction of drinking water consumption in the zoo

The primary goal of the project is the overall reduction of water consumption and the protection of its resources, especially drinking water from the water supply system, the production, distribution and subsequent treatment of wastewater is associated with the creation of a carbon footprint and the burden of central water sources.
...


2. Increase water retention in the landscape

Another task of the project team is to support water retention in the landscape. This will help to stabilize the local underground and surface water reserves of independently managed zoo-type areas. This will strengthen their resistance to periods of drought. Urban water retention also reduces the load on the sewage system, which reduces wastewater discharge and the associated pollution load on surface waters, including problematic micropollutants.

3. Reducing the carbon footprint

Water recycling using a combination of close-to-nature water purification systems and modern water treatment technologies will reduce the zoo's carbon footprint. The technology is designed with regard to minimizing the consumption of electrical energy from the distribution network.

4. Improved quality of life for farmed animals

Circular water management will make it possible to operate a higher capacity of water bodies and reservoirs with a clearly positive effect both for animals and for visitors and residents of the adjacent urban development. At the same time, the tanks will serve as storage capacities for the capture of rainwater and its subsequent use. Urban zoos with enough water for water reservoirs and irrigation green contribute (similarly to parks) to the formation of heat islands - they reduce the temperature in nearby buildings and co-create the "green lungs" of the urban environment.
...

Circulating water brings a number of advantages and benefits.



The first benefit of circular water management is the reduced dependence on primary water sources. By reusing water, we minimize the need to pump new sources, thereby protecting the natural environment and preserving aquatic ecosystems.

The second important factor is cost reduction. Circulating water allows more efficient use of resources and minimises wastewater, leading to lower operating costs. In this way, we can save money and invest it further.

Water in the zoo

30.11.2023

October's Water Thursday took us to the zoo. And to several of them. First of all, Tomáš Lederer from the Technical University of Liberec introduced us to the project of complex changes in the water management of the Liberec zoo. The large-scale project, which focuses mainly on maximizing the use of natural water and recycled water to reduce drinking water consumption, is not just a project on paper, but will be implemented over the next year. The lecture was perfectly complemented by the input of the zoo's director David Nejedl. He mentioned, among other things, how challenging it is to raise money for projects like this, as these invisible projects score few political points.

Czech-German Climate Dialogue Liberec: together against climate challenges

23. 11. 2023

The climate "boiler" is not going out and the impacts of climate change are tangible in the Czech Republic and Germany. That is why both countries have organised the Czech-German Climate Dialogue, a series of expert meetings in Prague, Brno, České Budějovice and Liberec. In Liberec, lectures and discussions were held on urban climate adaptation, and several presentations were given by experts from practice - cities, universities and zoos from both the Czech and German sides of the border.
