The project Heawater improved water quality in selected small urban rivers by preventing nutrients and hazardous substances inflow from watersheds to Baltic Sea.
Partners from Estonia, Sweden and Finland developed and tested new technological solutions that were specially designed for small rivers to reduce pollution load. The most suitable solution for each selected small river was tested as part of the pilot investments that were carried out in Tallinn, Söderhamn and Turku. Monitoring data shows reduction in concentration of selected indicators more than 10%.
