Abstract [en]

Water is essential for our daily life. Despite this, much of our water has become polluted and nutrient-enriched. One main factor contributing to the problem are private sewers. In total, there are nearly 1 million private sewers in Sweden, which represent one of the largest point sources of nitrogen and phosphorus. A survey was carried out to investigate the status of private sewers at Källsjön, Sollefteå municipality. In addition, four municipalities around Sollefteå have been interviewed about the implementation of legislation concerning private sewers. The study shows that sewers around Källsjön are seemingly in relatively good condition. However, 36% of the polled property owners have drains that are over 20 years old, and the function of these drains can be questioned. Interestingly, many of the surveyed property owners do not even know how old their drains are and what type of facility they have. Three of four interviewed municipalities are currently not performing any active control of private sewers. All municipalities provided information to property owners regarding current legislation. The study suggests that municipalities should act proactively to establish comprehensive inventories, a first step towards raising the standard of the individual sewers.
