Wastewater treatment in small-scale wastewater facilities outside urban areas is substandard. A majority of the plants meet today, not requirements, and therefore need to be renewed, replaced or upgraded. The work has been limited to mini treatment plant, soil beds and phosphorus traps for individual small sewage oversized for 5 people. Evaluation of the different action alternative has been made using the multi-criteria analysis. This method is the collective name for a number of methods used in difficult decision situations to ensure that the best decision. In implementing the MCA has a linear additive method is used where the final selection of criteria and indicators took place within the project. A reference group that has a great overall competence in this matter made the weighting of the criteria. The criteria were selected for assessment of the various options was purifying capability, power consumption during operation, the potential recycling of nutrients, cost, robustness, user friendliness. The option were assessed and graded then for how well they performed against the developed criteria and after that summed weighted grading calculated obtained a ranking of the different action alternative. MCA performance matrix provide an overview of the different options has performed against the various criteria and their final preference and ranking.
