Description

Sanitation: ventilated improved pit (VIP) latrine construction This man is attaching a fly screen to the vent pipe of a VIP latrine in Lesotho. A screened pipe prevents flies from entering or being able to escape from the latrine. The pipe may be fitted with a corrosion-resistant flyscreen of plastic, stainless steel, or aluminium. Broken screens must be replaced quickly. Flies are positively phototactic and will be attracted to the light at the top of the screened pipe. Flies may enter the pit via the latrine hole but are trapped when they emerge, reducing the spread of infectious diseases.
