Global Knowledge Based Technologies for Water Supply and Sanitation in Rural and Peri-Urban Areas – An Integrated Approach for Various Stakeholders and Decision Makers
Access to improved water supply and sanitation remains a big challenge for the developing world. This paper reviews global knowledge based technologies and practices for water supply and sanitation, including reuse and recycling technologies while focusing on technologies for the rural and peri-urban areas in developing countries. The review is based on a compilation of existing information provided by scientific literature, project
reports and technical data sheets from international organisations. Differences between various technological systems for water supply and sanitation are considered. By classifying (waste) water treatment systems along with matrices and by using complexity and treated water/effluent quality as the main criteria, this paper gives a logical and understandable overview of different stakeholders and decision makers operating in the water sector. For sanitation systems an additional matrix was constructed with sanitation systems classified using size (of population to be served) and water demand as criteria.
