As part of Łódź’s strategy for green and climate-resilient infrastructure, one of the city courtyards will soon feature a Sustainable Urban Drainage System (SUDS) aligned with international sustainable development goals and UNESCO recommendations.
What did we find?
➡️ The courtyard was 100% covered in impermeable concrete.
➡️ No water retention – rain simply drained away.
➡️ No greenery – contributing to poor microclimate conditions.
What are we implementing?
-
🔨 De-sealing – removing concrete to expose and restore natural ground.
-
💧 Capturing rainwater directly from drainpipes.
-
🌊 Creating an open water channel – both functional and visually appealing.
-
🛢 Installing six decorative rainwater tanks (650L each) for reuse in plant irrigation.
-
🌿 Introducing plants and greenery chosen to suit local soil and water conditions.
Why does this matter?
In line with UNESCO’s ecohydrology approach:
-
It reduces flood risks.
-
Supports natural water cycles.
-
Helps cool urban spaces.
-
Improves residents’ quality of life.
The project is based on detailed studies: soil surveys, rainfall data modeling, and existing infrastructure assessments. All works are designed with full respect for the buildings and existing urban systems.
This initiative marks an important first step in revitalizing Łódź’s courtyards with sustainable water management at their heart.
