Abstract
It is generally recommended that solutions for the treatment of wastewater and toilet waste is based on a detailed knowledge of the local physical and natural conditions as well as socio-economical factors and socio-cultural factors. Based on experience from previous comparable projects the following components are recommended: " The systems should be build as large as possible based on local natural/financial resources " Infiltration systems are preferred if local soil is usable and local water resources are protected " A combination with pre-treatment, compact filtering and extensive filtering in wetlands or peat filters Based on experience from previous comparable projects the following components might also be recommended given a local acceptance: " Urine separating toilets without water/low water consumption " Separate collection of urine in tanks to be stored and reused or safely disposed off " Toilet solid waste to be stored in separate tanks and co-treated with other organic waste fractions " Separate treatment of greywater and urine in extensive infiltration or filter systems These systems makes it possible to a safe, odour free and recycling waste and wastewater treatment without creating unacceptable loads on the environment or risks to human health. Infiltration systems depend on local soils and previous use of ground water.

Abstract
City planners need practical methods to assess and compare the sustainability of different alternatives for urban infrastructure. This article presents the consequences of selecting different methods to normalize the values of sustainability indicators, and the influence of selecting different indicators and different weighting techniques. A nature based sewerage system is compared to a conventional system. The article demonstrates that the method used to normalize the indicators, the choice of relevant indicators and the weighting technique have considerable influence on which system is found to be the most sustainable. By selecting particular indicators, weighting and normalization methods, it is possible to prove that virtually any infrastructure system is more sustainable than any other alternative system. Such a biased approach is difficult to reveal unless the most careful, expert scrutiny is applied. Because of this fact, it is of paramount importance that the consequences of different evaluation methods are discussed and sensitivity analyses are carried out honestly and objectively on the critical parameters. An evaluation process made in this way will enable those parts of the analysis that generate disagreement to be identified, and decisions taken on what is important and unimportant.
