The current view in Kokemäki, western Finland, is not very merry or bright as the water levels keep rising...
But, the NOAH team still wishes everyone a peaceful Christmas and a good start for the year 2020. ✨

NOAH communication team from SAMK visiting Turku in Southwest Finland with two fruitful meetings. First, project insights with the Union of the Baltic Cities (UBC), one of the associated partners of NOAH. Second, good discussions on finding synergy with the Centre for Economic Development, Transport and the Environment (ELY), the leading institution for flood control measures in the region.

NOAH cooperation in Latvia! By using the methodology from the NOAH project, Jurmalas Udens Ltd. would like to increase the number of inhabitants who will switch from decentralised wastewater solution to centralised sewerage. Senior researcher Jānis Rubulis and scientific assistants Marta Frolova and Gints Dakša from Riga Technical University visited Jurmala to discuss the benefits of the NOAH project for Jurmalas udens Ltd with Aivars Kamarūts, Kristīne Bendža and technical director Guntis Klīve. Lots of important knowledge about online flow, level meters as well as water quality sensors and sampling methodology was shared. The work continues!

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

An insight about the NOAH progress meeting held in Copenhagen in September 2019 by Klara Ramm from the Economic Chamber Polish Waterworks (IGWP). Plenty of interesting project information in Polish!

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!
