Invitation to experts to join the Stakeholder Representative Panel of Baltic Sea Region, BSR NOAH:

BSR NOAH (Protecting Baltic Sea from untreated wastewater spillages during flood events in urban areas) project is establishing a Stakeholder Representative Panel to ensure the transnational value to be verified and documented through the various channels used in communication as a part of WG5 Communication: Exploitation strategy.

Outputs of BSR NOAH are formulated as the NOAH concept which will be introduced to the Stakeholder Representative Panel for discussion and joint development. The Panel will have 3 hours online meetings, five in number. Stakeholder Representative Panel members are also welcomed to participate NOAH events.

We invite stakeholders from the Baltic Sea region (esp. Russia and Lithuania) and beoynd to join the panel.

Please indicate your interest to be a member of the NOAH Stakeholder Representative Panel by 31st of January 2020 (email: minna.keinanen-toivola(at)

NOAH regional workshop in Finnish will be held in the Meremme tähden / For the Sake of our Sea event in Rauma, Finland, on the 7th of May 2020.

NOAH Lead Partner representatives Nils Kändler and Katrin Kaur from TalTech visited project partners in Söderhamn, Sweden. They had a productive meeting with the local operators clarifying the details of the Söderhamn pilot area model. In addition, a presentation of the project objectives and Söderhamn activities was given to the political representatives of the municipality of Söderhamn.

Last year we started assessing current progress and needs of cities in #stormwater management.

First findings 👇

We still accept input from cities to expand on the legal perspectives, approaches and needs in this topic! Share your experience 🖊️

NOAH communication team visiting Turku, FI, for two great meetings: project insights with @UBC_Sustainable, NOAH associated partner, and discussions on synergy with @VarsinaisELY, the leading institution for #floodcontrol in the region.

The Satakunta region in Finland is currently under #flood warning. The flow in the local river has tripled in a month. 💦 Comments of the #floodprotection experts of Pori, a #BSRNOAH partner, in the article (in Finnish).

Team @sub_samk /@SatakunnanAMK for @BsrNoah is ready and excited for @baltic_sea_prog workshop on target group involvement. #BalticSea #floodcontrol #mysamk

More about NOAH

Floods causing inflows of pollutants into the Baltic Sea

Effective control of the stormwaters in urban areas is one of the biggest environmental challenges in the Baltic Sea region as climate change brings along intense rainfalls and storms. Urban drainage systems are not capable to handle the floods, which rises the risk of flushing untreated wastewater from urban drainage systems into the nature. This is harmful to people and environment due to the excessive amount of nutrients, hazardous substances and pathogenic microbes in wastewater.

Holistic planning and smart drainage systems

Urban areas can be prepared for floods by improved planning and self-adaptive drainage operations. NOAH project brings together nine towns and water utilities, seven academic and research institutions and two umbrella organisations from six countries around the Baltic Sea to join their forces.

NOAH’s approach is to create a concept for holistic planning and implement smart drainage systems in real urban environments. Holistic solutions combine stormwater management with spatial planning. This is followed by development of smart drainage systems to make the existing facilities resilient to the impacts of climate change.

Healthier and cleaner Baltic Sea

The NOAH concept will be easily scalable to any urban area around the Baltic Sea. Implementation of the concept could cut up to half of the inflow of pollutants into the Baltic Sea. The activities will be anchored into daily practices of towns and water utilities, leading to healthier and cleaner Baltic Sea!
