Retenční nádrž Ořech

Retenční nádrž Ořech is a water storage basin in Prague designed to capture heavy rainfall and reduce flood risk in the surrounding neighborhoods. The basin is enclosed by walking paths with grass banks and planted areas that blend into the local landscape.

The basin was built in the 1990s as Prague needed better protection from increasing flood events. Its construction marked a shift toward incorporating water management directly into urban development.

The site demonstrates how practical water management blends with green space in an urban setting. Locals use the walking paths as part of their daily routines, turning infrastructure into a neighborhood gathering place.

The walking paths around the basin are freely accessible and well maintained year-round. The terrain is flat and easy to navigate, making it straightforward to explore on foot or by bicycle.

The basin transforms visibly after heavy rain, filling up to show water management in action. This dramatic change makes it a place where visitors can actually witness how the city handles stormwater in real time.
