Bosnia and Herzegovina faces a significant investment gap of 3.5 billion euros to meet EU Urban Wastewater Treatment Directive (UWWTD) requirements, with only 20 operational treatment plants currently in place. The report suggests that BiH can leverage Sweden's experience in sectoral knowledge sharing, inter-municipal cooperation, and the use of both centralized and decentralized systems to improve sustainability. Key recommendations include adopting the 2024 Master Plan for Agglomerations, developing entity-level sludge management plans, and bypassing traditional linear models in favor of circular resource recovery for water, nutrients, and energy.

Bosnia and Herzegovina faces a significant investment gap of EUR 3.5 billion to meet EU wastewater standards, with only 20 operating treatment plants. The report compares the fragmented institutional landscape of Bosnia and Herzegovina with Sweden's more integrated approach, highlighting the role of trade organizations like Svenskt Vatten and inter-municipal collaborations like NSVA. It suggests that Bosnia and Herzegovina can 'leapfrog' traditional centralized systems by adopting circular resource recovery principles for water, nutrients, and energy, and by tailoring solutions to the specific scale of urban and rural agglomerations.

The HydroHazards project develops frameworks to analyze how simultaneous or sequential hydrometeorological events impact critical infrastructure and create social vulnerabilities. A national analysis of Sweden indicates that while extreme precipitation, river streamflow, and sea levels rarely coincide in one location, the south and west coasts are more prone to simultaneous floods and extreme sea levels. In the municipality of Halmstad, the project applies a mixed-methods approach—combining network analysis, synthetic distribution networks, and the Impact Chain model—to identify how infrastructure failures lead to cascading effects on the population, distinguishing between underlying social vulnerabilities (e.g., income) and emerging vulnerabilities caused by service disruptions.

The document examines how climate-driven extreme weather events, such as floods and droughts, create cascading failures in essential services that disproportionately affect vulnerable populations in Halmstad, Sweden. It identifies key drivers of social vulnerability—including age, income, and disability—and argues that municipalities should integrate social perspectives into their risk and vulnerability analyses of critical infrastructure to improve crisis preparedness.
