The challenge

According to new regulatory requirements, since 2017, the city of Trollhättan’s share of rainfall dependant infiltration inflow in the municipality must not exceed 60% by 2023, from the current of 70%. The challenge is to visualize and communicate the impacts and effects of such new regulatory requirements and to help identify targets.

1. The city of Trollhättan was able to create a well-documented review of the effects and costs of their carried-out measures, as well as a realistic plan for the coming 10 years with regards to achievable outcomes and budgets. This was communicated to the county regulatory board who reviewed the regulatory requirements set in 2018, with the aim of developing new regulatory requirements.
2. For the city of Trollhättan, implementing Future City Flow resulted in improved insight into what catchments contribute the most to their current and future problems. It also provided a visual platform for comparing different scenarios. This visualisation helps for collaborative decision-making.
3. The newly established 10-year plan will result in more targeted efforts at a lower cost and will help Trollhättan meet their targets.
