SWaM is responsible for the supervisory guidance of small-scale wastewater treatment systems, in other words systems for up to 200 people (or their equivalent). Our guidance is intended for use by authorities dealing with inspection and licensing/permitting (municipalities) and regional guidance (county administrative boards).
We do not decide how other authorities are to act in individual cases. We also do not provide advice to property owners as to which wastewater treatment solution they should choose. Property owners who are dissatisfied with a municipal decision have the right to appeal to the county administrative board.
The Swedish Environmental Protection Agency (Naturvårdsverket) publishes guidance for county administrative boards and municipalities, on
- treatment facilities designed for more than 200 people
- facilities designed for treatment of wastewater from actitivities other than households
- sewage sludge and other waste from treating wastewater.
