conference contribution
posted on 2018-02-12, 15:08 authored by L.M. AustinThere are approximately 50 000 urine diversion (UD) toilets in South Africa. Emptying the vaults implies that the faecal
material must be handled, usually with spades or rakes. Should the material be used for agricultural purposes then further
handling must of necessity take place. There are currently no guidelines in the country on the safety aspects of handling
faecal material from UD toilet vaults, particularly regarding the storage period required for achieving satisfactory pathogen
die-off. This paper describes a research project carried out in Durban with the aim of establishing a recommended
vault storage period for the material. The research concluded that the toilet vaults should be sized for a minimum storage
period of 12 months after last use.
