RETROUT is a ‘Blue Growth’ project funded by the EU-INTERREG Baltic Sea Region Program and Roslagens Sparbank Foundation. The main objective of the project is to improve the potential for coastal fishing tourism in the Baltic Sea Region through improved ecological health of the rivers, strengthened governance for fishing tourism and the development of the fishing industry. Nandita Singh, a docent from KTH and currently employed as a project leader at UCV, is responsible for a sub-project within RETROUT, which will investigate the causes of the problems by comparing successful and failed river restoration projects. Failed projects are those that were never implemented, did not have the intended effect or had low cost-effectiveness. In each project data is gathered about the ecological effect of installed fishing routes, costs, construction time, legal processes and other difficulties. In a communication study, business owners and involved authorities will be interviewed. By comparing these data between successful and failed projects we will be able to propose methods and procedures for future restoration projects. The results of the comparative study will be tested in pilot projects in Sweden, Estonia, Latvia and Poland. In Norrtälje, the result of this part of the project will be applied to Skeboån to improve the trout stock. Then, the project will improve Norrtälje Municipality’s potential for sustainable fishing tourism by supporting local actors training fishing guides and developing fishing tourism offers. The combined results from the comparative study and the pilot projects will be summarized and finally contribute to the ‘Baltic toolbox’ that will contain recommendations on “Best Practice” for river restoration. The project will run from 2018-2020 and led by the Stockholm County Administrative Board, with Sweden, Latvia, Lithuania, Poland, Estonia and Finland as partners. The total project budget is 3.6 million Euro.

Establishment of a research platform

We establish a research platform to help solve Norrtälje municipality’s challenges in the water sector.

Norrtälje municipality has a wide range of challenges regarding water, with several issues such as lack of water and wells with quality problems and nutrient. Norrtälje has the largest share of individual wastewater of all Swedish municipalities. Norrtälje municipality is esteted to have about 33 000 individual sewers, most in the country. In addition, the ongoing transformation of leisure areas into permanent housing entails a great need to be able to strategically plan for even greater stress on water resources and recipients.

The research platform will be established by connecting to universitys and colleges that will be able to place research and education in the area of Campus Roslagen. Primarily, research projects will be about small-scale drinking and wastewater technology as well as strategic social issues related to these. For example water scarcity and pollution frome individual sewers and community planning in areas on the coast and in the archipelago.

Norrtälje has a strategically very good location between Stockholm, Uppsala, Åland and Finland at the same time as sparsely populated and archipelago municipality is an excellent place for field studies, especially considering the challenges.

Test bed Drinking water

Test bed drinking water is a VINNOVA-funded project led by the Development Center for Water at Campus Roslagen i Norrtälje. We collaborate with companies that work with small-scale drinking water technology for household purposes, as well as with authorities and academies.

Many private properties in Sweden are not affiliated with the municipal water supply. There is a market for small-scale drinking water purification technology. Society’s increased awareness of drinking water quality means that this market is growing. In particular, water filters and RO plants are increasingly used and today many small companies offer different products. In Sweden, on the other hand, it is still unregulated with the quality of drinking water for private use (for up to 50 persons) and legal requirements need to be developed. Today, great demands are placed on the owner, since it is up to him to check that his water is decent.

The idea of the test bed is to offer companies the opportunity to test and develop various small-scale techniques to make unsuitable water drinkable under different operating conditions. We will also be able to test filter material separately and other materials in contact with drinking water. The goal is to be able to offer quality certification for efficiency and sustainability tests.

We are currently rebuilding a municipal waterwork in Norrtälje municipality. The waterwork gets water through three wells with different water quality, which means that the facility offers the opportunity to test water purification equipment in a so-called constructed user environment. After that, most measurements needed for drinking water tests can be performed in our lab.

Norrtälje municipality is a very suitable region to establish the test bed in because it has among the highest number of summer houses in Sweden. In addition, many of these houses are converted into permanent housing. The test bed is expected to be ready for test projects in the first quarter of 2019.

First stage of the project: pilot SITE 0 on Kaserngatan 11 is completed and the first filter has been tested. Are you interested or would you like to know more about the project, please contact Amelia Morey Strömberg via e-mail or phone 0176-28 61 17.

Test bed wastewater

Test bed waste water is a VINNOVA-funded project led by us at Development Center for Water. We collaborate with companies that works with small-scaled sewage treatment technology, as well as with authorities and academies.

New rules on discharges of waste water to surface and groundwater means that many households today need to upgrade their solutions. There is a market for small-scale sewage treatment technology. The idea with this test bed is to offer companies the opportunity to test and develop, mainly, ground-based sewage treatment technology, e.g. infiltration or ground beds. Right now, we are planning how the test facility will be built and organized. We intend to build a test bed with the possibility of installing about 6 sewage plants. From nearby apartments, we will pump sewage into each sewage system. The test bed offers the opportunity to test sewage treatment technology in a so-called constructed user environment. Then we can make most of the measurements needed in our lab. The planning phase is expected to be completed in the last quarter of 2018 and we intend to start building it in 2019. Norrtälje municipality is a very suitable region to establish the test bed in because the municipality has the highest number of summer houses in Sweden that are depended on small-scale sewage treatment technology. Many of these houses are also converted into permanent houses.
