Testing new storm water treatment solutions for reduction of hazardous substances and toxins inflows into the Baltic Sea

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

To achieve these results, the project will address issues related to the 1) cleaning of stormwater with equipment/facilities, 2) quality system management and 3) e-monitoring of hazardous substances and toxins.This will lead to the development of near real time water quality monitoring devices that will be tested and implemented. The data related to the operative response to emergency cases will be collected to improve their functioning and for scientific purposes. The criteria for Quality Management  and a set of corrective modifications will be implemented in the test areas of the participating countries by building centralised stormwater treatment solutions in Estonia and Latvia, and two decentralised solutions in Finland.

The Project partners will test the following new technical solutions:- a centralised multi-stage storm water treatment & monitoring system in Viimsi, EE;- a centralised stormwater treatment unit equipped with real-time sensors for monitoring in Riga, LV;- a decentralised bioretention basin/cells with monitoring functionality in Lieto and Turku, FI. In all areas, the technical solution of storm water treatment will be accompanied with a water quality system management and monitoring in near real time thus enabling operative response in emergency cases. Municipalities and cities will be equipped with criteria, instructions and tools for ensuring the quality management of stormwater management structures during the project life cycle.
