in his speech for the launch of the UN International Year of Sanitation 2008 the UNSGAB-chair Prince Willem-Alexander from the Netherlands pointed out the importance of reaching the water supply and sanitation MDGs in a sustainable way. Reuse of excreta and wastewater is promoted and the agricultural and energetical value of excreta and wastewater is stressed.
From the educational point of view he named the community-led total sanitation campaign in India as a good approach (well, there are pros and cons about that one – would be interesting to hear your opinion on the total sanitation campaign). From a technological point of view, Urine-Diversion toilets are named as a new innovation (considering that more than a million are installed in China it is not really something novel but good that it was mentioned). Other appropriate systems to reach the MDGs are given with “small-bore sewerage systems, pit emptying facilities, low-cost septic tank sludge treatment methods and the development and marketing of biogas technologies” – addressing bigger problems of low-cost decentralized conventional treatment systems… thinking of climate change, it would make more sense for me to invest into upgrading septic tanks to anaerobic digesters and pit latrines into Urine Diversion Dehydration toilets – then we also fight Methane-emissions… but just some thoughts…
