Greywater Management in Low and Middle-Income Countries


Greywater Management in Low and Middle-Income Countries
Review of different treatment systems for households or neighbourhoods

by Antoine Morel and Stefan Diener

Publisher: Dübendorf, EAWAG, 2006



This report prepared by EAWAG within the framework of the NCCR North-South compiles international experience in greywater management on household and neighbourhood level in low and middle-income countries. The report is not a plea for stand-alone greywater management systems for all situations and at all costs but aims at providing a comprehensive description of the main components for successful greywater management. Recommendations are formulated for control measures at the source, design of primary and secondary treatment systems as well as safe reuse and disposal of treated greywater. The documented systems, which vary significantly in terms of complexity, performance and costs, range from simple systems for single-house applications (e.g. local infiltration or garden irrigation) to rather complex treatment trains for neighbourhoods (e.g. series of vertical and horizontal-flow planted soil filters).
