This report presents and discusses the results from the dissemination of biodigesters for sanitaiton in Haiti from 2010 to 2013. Because the principle objective of the dissemination period was sanitation in the form of toilet provision and wastewater treatment, the term DEWATS (Decentralised Wastewater Treatment Systems) is used to describe the biodigesters. The secondary objectives that the biodigesters were to address were renewable energy (in the form of ‘biogas’); and nutrient rich digestate (in the form of effluent from the biodigesters, referred to in Haiti as ‘biol’).
The report shows that over the 4 year period, most of the biodigesters did not deliver on all of their objectives of sanitation, biogas and biol, although the majority of toilets connected to the biodigesters were evaluated as ‘functional’. There were isolated examples of success in all 3 objectives, for example in markets and in dense urban areas where users paid to use to toilets and the Operating Agencies acted diligently in the execution of their management tasks.
