The mixture of urine and faeces should never be used as it not only smells foul but also the slurry produced by this mixture has a high number of enteric micro-organisms. Urine can be treated by storing it separately for a period of six months; this makes it free of bacteria and safe for use in the fields. By consistently following these procedures, the presence of enteric bacteria, viruses, protozoa and helminth eggs in faeces can be fully controlled.
Some possible diseases due to partial treatment and unsafe use of night-soil compost are amoebic dysentery, human tapeworm, cholera or viral hepatitis. Safe and hygienic use of night-soil compost is important for protecting the health of the users, as well as the environment. In order to prevent diseases, proper management of night-soil and its treatment are essential. So for proper conversion of night-soil into compost, a series of control measures need to be followed. The World Health Organization has also produced guidelines relating to the safe use of wastewater, excreta and greywater (see Box).
