According to the WHO & UNICEF Joint Monitoring Programme (JMP), improved sanitation facilities are those that ensure hygienic separation of human excreta from human contact. As defined by JMP, IMPROVED sanitation facilities include: Flush or pour-flush toilets to piped sewer systems; septic tanks, pit latrines, VIP latrines, pit latrine with slab, or composting toilets. UNIMPROVED Sanitation facilities include: Shared facilities of any type, no facilities (bush or field); flush or pour-flush to elsewhere (that is, not to piped sewer system, septic tank or pit latrine); pit latrines without slab / open pits, bucket systems; hanging toilet or hanging latrine. This definition is received not without criticism, for instance because there is no reference to treatment of the toilet contents.
