New Rain Garden Supports Sustainable Water Management at SUA in Nitra

A new rain garden has been established on the campus of the Slovak University of Agriculture (SUA) in Nitra as part of the university’s efforts to promote sustainable water management and climate adaptation.

Located next to the recently renovated Innovative Laboratory for Agricultural Technology, the rain garden was designed and implemented by the SUA Botanical Garden team. The project combines water and vegetation elements to capture and retain rainwater from nearby roofs and paved surfaces, helping to reduce surface runoff and improve water infiltration.

The garden is designed as a shallow landscaped depression consisting of several filtration layers that allow rainwater to gradually soak into the ground. Covering approximately 150 m², the system collects runoff from more than 1,000 m² of roof area and surrounding surfaces.

In addition to improving stormwater management, the rain garden contributes to biodiversity, enhances the local microclimate, and provides an attractive green space within the campus. It also serves as an educational and research facility focused on nature-based solutions for water retention.

The garden is planted with 25 species of native grasses, perennials, and shrubs selected for their ability to tolerate changing moisture conditions and support ecological stability. Species include sedges, irises, meadowsweet, yarrow, and selected willow and dogwood varieties.

The project forms part of a broader vision for the campus. Future plans include expanding the rainwater collection system and developing the surrounding area into a multifunctional space for education, recreation, and outdoor learning.
