Climate change brings along intense rainfalls and storms in the Baltic Sea region. Urban drainage systems are not capable to handle this, and therefore floods are becoming more common in the densely populated areas.
Floods causing inflows of pollutants into the Baltic Sea
Floods rise 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 has brought 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.
