As stated by Brissaud (2008), “The potential contribution of water reuse to integrated water resources management still remains considerably undevel- oped, though a wide range of reliable, efficient and cost effective technical solutions are available for each type of reuse application. Economic considera- tions will inevitably lead the decision makers to opt for economically efficient reuse applications, i.e. urban and industrial water reuse in the short term and indirect potable reuse in the long term.”
