CleanStormWater

The objective of the project is to develop and test new storm water treatment solutions that will clean effectively storm water, ensure management quality and monitor water quality in near real time thus enabling operative response in emergency cases.

The CleanStormWater project aims in the development of stormwater management in Baltic Sea countries. Comprehensive approach from planning and implementation to monitoring is needed to ensure good stormwater management. 

As a result of Project, the amount of hazardous substances and toxins reaching the Baltic Sea will be reduced in pilot areas of participating countries by applying new solutions, which integrates the components of 
1) cleaning of stormwater, 
2) management quality and 
3) monitoring of hazardous substances and toxins. 

Piloting actions will take place in sub catchments located in the areas of Lieto and Turku in Finland, Tallinn-Viimsi in Estonia and Lucavsala and Zaķusala in Riga, Latvia. In these sub-catchment areas, the Project partners will test the following new technical solutions: 
•    a centralised multi-stage storm water treatment & monitoring system 
•    a centralised stormwater treatment unit equipped with real-time sensors for monitoring 
•    decentralised bioretention basin/cells with monitoring functionality 

In all areas, the technical solution of storm water treatment will be accompanied with management quality system and monitoring of water quality in near real time thus enabling operative response in emergency cases. Namely, municipalities and cities will be equipped with criteria, instructions and tools for ensuring the quality management of stormwater management structures during the whole life cycle.

Testing new storm water treatment solutions for reduction of hazardous substances and toxins inflows into the Baltic Sea – CleanStormWater project is Interreg Central Baltic funded cooperation project.
