� Socio-cultural criteria<br />
o General acceptance of <strong>greywater</strong> reuse<br />
o Ecological awareness<br />
o Pioneer in this area<br />
Regarding economic issues, no economic criteria of an assessed country such as per<br />
capita income or gross national product have been consciously included. It is due to the fact<br />
that such a high-tech plant like <strong>greywater</strong> recycling via membrane bioreactor is not a<br />
grassroot solution, which should be implemented in every single household. Additionally,<br />
MBR <strong>treatment</strong> <strong>system</strong>s are frequently installed in big buildings such as hotels, apartment<br />
buildings and halls of residence. In these cases, the economic situation of the investor does<br />
often not represent the financial situation of the country.<br />
In the next paragraphs the sub criteria are explained. They are included in order to explain<br />
the different issues and the weighting within the utility analysis. In total, the weighting of all<br />
criteria results in 100 % and every sub criterion is given a certain value. The complete<br />
overview of assessment criteria and weighting within the utility analysis is shown in Table 8.<br />
