Current news & events

Despite the beginning of the year 2020 being rather exceptional due to the Corona virus situation, the NOAH project has mostly proceeded as planned. The updates and progress are collected into NOAH newsletter January-June 2020.

The NOAH project establishes a Stakeholder Representative Panel in January 2020 to efficiently reach the stakeholders outside the project partnership and to ensure the transnational value of the project to be verified and documented in project communication.

The panel members – from Denmark, Sweden, Finland, Russia, Estonia and Lithuania – are all experts of water management and sustainability development in the Baltic Sea region. Project outputs, and finally the NOAH concept, will be introduced to the Stakeholder Representative Panel for discussion and joint development. The panel will have online meetings regularly in 2020-2021.

NOAH regional workshop in Finnish at the Meremme tähden / For the Sake of our Sea event in Rauma, Finland, on the 7th of May 2020 is cancelled due to COVID-19.

New date for the workshop will be announced later.

The Polish partners of NOAH gathered for a meeting in Słupsk. Preliminary modelling results for a selected area in Słupsk were presented by the Gdańsk University of Technology (GUT). Słupsk water utility introduced the partners the new sampler, pluviometer and flow meter. In addition, the team took samples from Słupsk combined sewer system. The wastewater content will be then analyzed by GUT and the results will be used for further work on the modelling of the pilot area. 💦👍 #bsrnoah #InterregBSR #slupskwaterutility #modelling #pilotsites ...

The installation of investments in the NOAH pilot area of Liepaja municipality in Latvia has started. The first activities include the installation of a physical measuring rod in one location of the Cietokšņa channel near Lībiešu iela. The location will be also equipped with a GSM card so that the data about water level rising can be transmitted online. This Automated Hydrological Station (AHS) investment will serve in decreasing the risk of floods in the lowest areas of the Jaunā pasaule catchment area.

Looking back at the NOAH progress meeting in Pori, Finland. Joyful partners and excellent cooperation for the good of our Baltic Sea! #bsrnoah #interregbsr #EUinmyregion #balticsea #partnership

#WorldWaterCongress next year will have a session on #BalticSea. @BsrNoah team is one of the co-organizors of the session. @SatakunnanAMK #mysamk #savethesea #floodcontrol

NOAH #partners were not able to meet in Gdańsk this month as planned, but the work sure continues as planned. Happy faces after a successful NOAH progress meeting #online!

We're always into cooperating with projects and sharing outreach methods! Reaching outside the partnership - @BsrNoah example with Stakeholder Representative Panel and regional workshops to approach target groups.

NOAH aims to reduce wastewater spillages during floods

NOAH at the @BSRWater Platform meeting. Looking forward to having an overview on good practices and solutions within #stormwater management. #bsrnoah #bsrwater #balticsea #interregbalticsearegion

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!
