Numerous technologies exist for the collection, treatment and reuse of excreta, greywater or wastewater. Here, we provide technology reviews for some technologies commonly used as toilets or as treatment systems in ecosan systems. For a more comprehensive review of technologies, please refer to the Eawag-Sandec Compendium of 2008 (see under further information > further publications > recommended reading) or to the working groups of the SuSanA (see under Cooperation > SuSanA).
