Abstract [en]

The aim of this project was to describe and to evaluate five small sewage treatment plants in the municipality of Laholm, Sweden, in order to investigate the treatment efficiency and to evaluate if effluents comply with discharge permits. The treatment systems were designed to treat effluents from 90 to 500 population equivalents. A report on the design and the present state of each sewage treatment plant has been made. This was made based upon previous documentation on water quality and by new sampling campaign as there were only a few previous measurements. Data has been evaluated and remedial actions proposed for those treatment plants that don’t fulfill discharge permits. Based upon the scientific investigation in combination with visits to the plants, discussions with the technicians in charge of the operation and literature study the following conclusions have been made:

The sewage treatment plant in Hishult doesn’t comply with the permits and the plant will soon be totally renovated.

Mästocka and Kornhults sewage treatment plants are complying with discharge permits and will be left without further actions at the present time.

Skogaby sewage treatment plant is in need of remedial action and I recommend focusing on the later treatment stages of the plant (pond and infiltration unit).

Öringe sewage treatment plant needs to be further investigated before suitable remedial actions can be proposed.
