Development of sustainable urban drainage systems in Eastern Europe: an analytical overview of the constraints and enabling conditions

We focused on the barriers to the implementation of enabling environments for sustainable urban drainage systems (SUDS) in Belarus, Russia, and Ukraine. Based on interviews and desktop research, we analyzed overall framework conditions in these countries as well as implementation practices in three cities. Our findings demonstrate that the main problem was the deficit of strategic foresight for urban development. SUDS are mostly promoted by NGOs and fueled by international donors, and this represents a major barrier to their implementation, as NGOs and ‘traditional’ epistemic communities are often not connected. Successful examples of SUDS are missing, often due to regulatory environments forcing SUDS development teams to take suboptimal decisions. In order to be taken seriously by key stakeholders SUDS need to appear in national policy documents. Furthermore, the overall successful implementation of SUDS needs robust governance frameworks while many structural issues are direct results of governance deficits.
