Small-scale wastewater treatment systems: governance, efficiency, resources recovery, environment contamination risks and innovative solutions for processes optimization (01/2019-12/2021)

EU budget: 504 726 €

Total Budget: 776 503 €

Project goals

  • To examine the governing principles of wastewater treatment systems not connected to sewage networks in Finland, Sweden and Norway as a means to highlight practices, strategies and regulations with the best outcomes in relation to environmental protection as well as social-economical and sustainable development.
  • To increase the available knowledge and thus our capabilities to estimate purification efficiency of small-scale wastewater treatment systems and the risks of environmental contamination from discharged pollutants (regulated and unregulated substances) in northern regions.
  • To test and develop innovative engineering solutions for improving removal of target substances (N and selected micropollutants) in small-scale wastewater treatment systems as well as to evaluate environmentally feasible options for resources recovery from sanitation systems in Nordic regions.

Project partners

  • University of Oulu (OU, Water, Energy and Environmental Engineering research unit, Project leader, Finland),
  • Luleå University of Technology (LTU, Department of Civil, Environmental and Natural Resources Engineering, Sweden) and
  • Finnish Environment Institute (SYKE, Laboratory Centre, Freshwater Centre and Centre for Sustainable Consumption and Production, Finland).

In addition, local SMEs, municipalities and environmental authorities are also actively involved in the project activities. The project will run for 36 months and it has started on the 1st of January 2019.
