PRESTO combats eutrophication by improving municipal wastewater treatment with technical studies and concrete investments as well as by increasing human competence. Eutrophication is the main environmental problem of the Baltic Sea and of many inland water bodies. It is caused by overload of nutrients. One of the fastest and most cost-efficient methods to reduce the nutrient load is to improve the municipal wastewater treatment processes in the Baltic Sea watershed.

Project is funded by the INTERREG IVB Baltic Sea Region Programme 2007-2013

Project Duration: 09.06.2011 - 08.03.2014
Approximate total project budget in EUR: 4.5 Milj. EUR
ERDF co-financing: 1.1 Milj. Eur
ENPI co-financing: 2.8 Milj Eur



To decrease transnational nutrient load to the Baltic Sea by at least 500 tons per year and at the same time to improve water quality of trans boundary River Daugava and River Neman. This will be reached by implementing low-cost, high-impact pilot investments on nutrient removal in four municipal WWTPs in Belarus (Grodno, Baranovichi, Molodezhno, Vitebsk) and by further developing the process in Latvian (Daugavpils) and Lithuanina (Kaunas) WWTPs.

To increase the competence of operating staff of the waste water treatment plants, plant designers and trainers of future wastewater engineers. This will be reached by organising a series of courses on modern waste water treatment and showcasing practical examples of reconstruction projects in their different stages. Technical University of Berlin is responsible partner for organizing the courses.

To increase awareness in the Baltic Sea Region about the harmful effects of nutrients in watercourses and how to tackle the problem. This will be reached by organising three targeted dissemination forums and continuous dissemination on different medias.
