As the main result, the pollution to the Baltic Sea from the stormwater systems has been reduced in four pilot sub catchments - Viimsi (EE), Riga (LV), Turku (FI) and Lieto (FI) by applying new solutions in integrated cleaning of stormwater, management quality and real-time monitoring of water quality parameters. All pilots remain in active use of the participating municipalities.

Additionally, the project demonstrated a fruitful way of cooperating between local governments and higher education institutions in innovation for improvement of the environmental condition of the Baltic Sea. The project offered an excellent opportunity to bring together the best specialists from the participating countries for joint implementation. The project results provided to develop guidelines for constructing the wetlands and establish permanent sampling/ online monitoring systems.
