 The NERSCOS2 project is about reducing the nutrient flows to the Baltic Sea from the near-coast touristic areas. It's about answering the seasonality problem that is driven by the excess of wastewater flow, especially in the summer season. The differences in seasonality in terms of wastewater flow are quite massive. They can account from three to even 20 times more wastewater generated locally depending on the location. It is important for the Baltic Sea, especially in terms of the nutrient loads that are discharged from the small-scale wastewater treatment plants lower than 2,000 person equivalent, because in most of the cases these plants are not so well monitored as larger ones, even if they bring less nutrients than the larger ones, but locally they can cause new traffic problems and also they can cause smell and other noises to the citizens and to the tourists. In this project we are going to design, construct, implement and test and replicate six pilot investments in wastewater treatment plants in Denmark, Poland, Latvia and Finland. Apart from that there will be surveys, there will be wide project communication addressed to the target groups, a lot of social analysis with risk analysis in order to replicate our results wider to the public.
