Rainwater
At VSB – Technical University of Ostrava, we are actively focusing on the collection and use of rainwater as part of smart resource management. We have installed systems in several places across the campus to capture rainwater, which is then used for flushing toilets and irrigating green spaces. This approach allows us to efficiently conserve drinking water while also reducing energy consumption. Through this system, we contribute to the overall sustainability of the university and bring our campus closer to the vision of a modern smart campus with environmental consideration.
Currently, we have four rainwater tanks in active use, collecting water from roofs and enabling further utilization. These tanks are located at the following buildings:
- VSH with a capacity of 93 m³
- Building J with a capacity of 20 m³
- CEETe with a capacity of 25 m³
- EKF with a capacity of 96 m³
In total, we have a capacity of 234 m³ for rainwater retention. This water is used, for example, to irrigate the green areas of the campus and to flush toilets in the new buildings of the Faculty of Economics (EKF) and the Center for Energy and Environmental Technologies (CEETe). Tanks with a total capacity of 70 m³ for buildings D and E are in the project planning stage.
Reusing rainwater allows us to significantly reduce drinking water consumption, thereby lowering our environmental footprint. In addition to cost savings associated with campus operations, this system also contributes to long-term sustainability and responsible management of natural resources.
This project is part of VSB-TUO's broader strategy aimed at developing a "smart campus," where modern technologies are integrated with sustainable practices. We plan to continue expanding and optimizing systems that will help us use rainwater even more efficiently, such as in the production of green hydrogen.
Through this initiative, we not only protect the environment but also inspire our academic community to adopt a responsible approach to natural resources.
