Wroclaw
Wrocław is located in the valley of the Odra River in south-western Poland. It has about 640,000 residents and covers an area of 293km2. The city is characterised by its well-preserved historic centre, which contains structures from the medieval period. There is an area of dense downtown development around the centre, flanked by residential areas including block buildings and “green” homes.
The riverside location of the city creates both an opportunity for sustainable development and a challenging geographic constraint. The progressive urbanisation of areas outside the inner city and the rapid increase in surface sealing, alongside more frequent extreme weather phenomena caused by climate change, have led to issues with the existing rainwater drainage systems and flash floods. Since 2017, Wrocław has implemented sustainable rainwater management, reflected in Wrocław’s urban planning documents, particularly the City Master Plan and local land use plans.
Residents are also being empowered to contribute and encouraged via a grant programme to sustainably manage rainwater on their own premises. Residents can receive up to 80% co-funding to build a rain garden or install a rainwater storage tank. These micro-level interventions are a step towards achieving macro-scale ecological goals. The programme is accompanied by workshops, including some for children, showing residents that draining rainwater into the municipal sewage system wastes a precious natural resource.
