In most countries, setting up or adopting a regulatory framework is an essential step for the
development and social acceptance of wastewater reuse. Decision makers and politicians need clear, sound, reliable standards to endorse reuse projects. Regulations based on internationally
acknowledged guidelines are generally preferred. Although an international
effort to reduce discrepancies between current standards is highly desirable, regulations
must be adapted to suit each individual country’s context, health risk and affordability.
Regulations have a major influence on the choice of treatment technologies and hence on
the cost of reclaimed water reuse projects.
