‘Lessons learnt on Ecosan in Morocco’ is a short analysis of experience gained in Morocco especially in rural areas where people do not have adequate systems of evacuation of their wastewater. The rural population cannot afford conventional sanitation systems. In response to this, we have thought to promote ecological sanitation that recognises wastewater not as a waste but as a resource. The first Urine-Diversion Dehydration Toilets (UDDTs) were introduced in a rural village called ‘Dayet Ifrah’ in Morocco in December 2009. Since then, households are starting to see the advantages of UDDTs and the systems are becoming more and more accepted. The UDDT systems implemented in the village could be used as a model for Moroccan rural areas. This paper sets out how the Ecosan approach was successfully introduced in Morocco where people are motivated by reasons to improve this approach such as no smell, safety, comfort, privacy and water reuse. Results reveal that the users are satisfied with the Ecosan approach to cleanse their wastewater. Although Ecosan is relatively new to Morocco, it seems that it can succeed in very poor populations. The paper contains information on general experiences in the different countries and also lessons learnt on Ecosan in each country.
