Improved sanitation systems in rural areas

Published: 18 January 2019

In large areas of northern Scandinavia on-site sanitation systems are used. In a new project investigates the function of existing treatment systems, their effect on the environment, how the treatment efficiency can be increased and which alternative systems can be used.

On-site wastewater treatment units are designed to decrease the concentrations of BOD, pathogens and nutrients. However, in many units the treatment capacity is insufficient.

"On-site wastewater treatment units are subject to large variations in load. E.g. at tourist centres the highest load is at high season which affects the treatment efficiency", says Inga Herrmann, researcher within Urban Water Engineering at Luleå University of Technology.

In this project, the efficiency of on-site systems is investigated by sampling facilities in Sweden and Finland. The facilities’ environmental effects are assessed by monitoring soil and water quality. Alternative sanitation solutions facilitating a recovery of energy and nutrients are analysed.

"In Sweden, Finland and Norway regulations around on-site wastewater systems are partly similar but there are also substantial differences. In this project we want to share experiences and knowledge between the Nordic countries by collaborating with different stakeholders" says Inga Herrmann.
