Experiences and Lessons Learned – Introducing the Manual of Solutions for Nature-Based Stormwater Solutions

All of the MUSTBE project’s seven nature-based stormwater solutions have now been completed. What was the process like? What went right? What went wrong? The experiences throughout the entire process have been collected into an open access manual of solutions. We hope these stories will inspire, inform, and support the wider adoption of nature-based stormwater solutions across the Central Baltic region and beyond.

The manual of solutions showcases experiences from two sites in Estonia (Viimsi and Tallinn), two sites in Pori, Finland, two sites in Söderhamn, Sweden, and one site in Riga, Latvia. Each pilot site represents a unique context – different landscapes, governance structures, technical capacities, and community needs. Yet, all share a common goal: to reduce flooding, improve water quality, and create more resilient urban environments.

Rather than focusing solely on technical specifications, these case studies emphasise the practical aspects of implementation – the decision-making processes, collaborations, adaptations, and lessons learned. Each story is structured to reflect the full journey – from initial goals and challenges, through planning, design, and procurement, to implementation and reflection.
