Project Heawater

Achieving healthier water quality in urban small rivers of the Baltic Sea catchment by restoration of water bodies and preventing of nutrients and hazardous substances inflow from watersheds

Logod koos 1

Pilot investments in three municipalities are expected to reduce 10% of pollution load of nutrients, hazardous substances and microplastics from urban small rivers into the Baltic Sea. Each investment is targeted to a different solution: bank erosion prevention in Tallinn, site-selection and planning of measures in Söderhamn and different mobile filter/retention systems in Turku.
