Diverse utilisation of stormwater with the aid of “multi-dams”

The starting point for the pilot measure in Västervik Municipality was a large multi-purpose pond in Gamleby, which collects surface runoff from a catchment area of 80 hectares. It helps prevent flooding and, by adding a tap point, provides water for various uses in the surrounding area, including the irrigation of football fields and plantations, as well as the production of artificial snow for cross-country ski trails. Maintaining the pond’s ecological balance supports natural purification processes, making it possible to use the water drawn from the pond directly.

Building on this experience, a new generation of “multi-dams” was developed and tested. Compared to the Gamleby concept, these newer systems are smaller in scale. The goal: to place these “mini-multis” closer to potential users – where the water is needed – since transporting water over long distances turned out to be a major obstacle to broader use.

In addition to reducing groundwater consumption, multi-dams offer ecological benefits such as enhancing biodiversity and reducing nutrient loads, contributing to more sustainable water and land management.
