Concept / Summary

Dry (Water-less) Sanitation Technology ...

Why water-less / dry sanitation?

All people have the right to equal amounts of water. However, for sanitation is water needed at all? The HDR should advocate for saving of water resources and pollution from un treated waste water by promoting non-water based sanitation to combat poverty. These technological solutions are provides the same level of hygiene and dignity as water borne sanitation and also provides for the technological possibilities to re-use resources as urea and faeces on a local level for e.g. small-scale agriculture (aerobic composting). As to illustrate one of many, many good examples, I quote a paper from the 25th WEDC conference in Addis Abbeba 1999 on Environmentally Friendly and Hygienic Sanitation by Farley & Kilbey:

"Waterborne sanitation systems are the traditional technologies used in urban developments. However, these are not sustainable in water-scarce situations. The annual volume of water (almost invariably potable water) needed to flush away the 550 litres of waste produced annually per person is 15000 litres. Water-scarce communities cannot afford such luxury. Even communities with sewerage systems frequently do not have a sewage treatment capacity, or one which only serves part of the city – the World Resources Institute claims that 95 per cent of sewage in the Third World is discharged untreated. Environmentally and economically, there is a clear case in favour of composting latrines, if they can reduce pollution, reduce health risks, and still enable the user to perform, his or her functions hygienically and with dignity."
