A vacuum truck, vacuum tanker, vactor truck, vactor, vac-con truck, vac-con is a tank truck that has a pump and a tank. The pump is designed to pneumatically suck liquids, sludges, slurries, or the like from a location (often underground) into the tank of the truck. The objective is to enable transport of the liquid material via road to another location. Vacuum trucks transport the collected material to a treatment or disposal site, for example a sewage treatment plant. A common material to be transported is septage (or more broadly: fecal sludge) which is human excreta mixed with water, e.g. from septic tanks and pit latrines. They also transport sewage sludge, industrial liquids, or slurries from animal waste from livestock facilities with pens. Vacuum trucks can also be used to prepare a site for installation or to access underground utilities. These trucks may use compressed air or water to break up the ground safely, without risk of damage, before installation may begin. Vacuum trucks can be equipped with a high pressure pump if they are used to clean out sewers from sand. Other names used for vacuum trucks: vacuum tanker, "Sucker truck" (in Australia) or "Sewer Sucker", "Hydro-vac", or "vac-trucks" (in Canada) or "Exhauster truck" (in Rwanda, Malawi). Slang terms include: "honey truck", "honey sucker" (in India and South Africa), and "honeywagon", all (probably) derived from honey bucket. When a vacuum truck is used to transport fecal sludge then it can also be called "fecal sludge truck". Commercial vacuum trucks which collect fecal sludge usually have a volume of . However various smaller versions for specialized applications or low-resource settings can be found with tanks as small as . They generally use a low-volume sliding vane pump or a liquid ring pump to create a negative air pressure. The use of diaphragm mud pumps is less common, but with the advantage of a simpler design and usually lower overall costs. The disadvantage is that mechanical parts come into contact with the sludge, which is not the case for the more common vacuum pumps.

Sanitation worker

A sanitation worker (or sanitary worker) is a person responsible for cleaning, maintaining, operating, or emptying the equipment or technology at any step of the sanitation chain. This is the definition used in the narrower sense within the WASH sector. More broadly speaking, sanitation workers may also be involved in cleaning streets, parks, public spaces, sewers, stormwater drains, and public toilets. Another definition is: "The moment an individual’s waste is outsourced to another, it becomes sanitation work.

Gestion des boues de vidange

vignette|Démonstration d'une nouvelle pompe pour vidanger les boues d'une latrine à fosse, près de Durban, en Afrique du Sud La gestion des boues de vidange (GBV), aussi appelée gestion des boues fécales, désigne la façon de gérer le contenu des fosses septiques et fosses de latrines, dont la vidange, le transport et le traitement. Elle s'occupe du mélange d'excréments humains et d'eau qui est stocké dans les systèmes décentralisés, par opposition aux eaux usées transportées dans les égouts et aux boues d'épuration qui en proviennent.

Assainissement non collectif

L'assainissement non collectif (ANC) ou assainissement autonome est le traitement des eaux usées domestiques produites par un immeuble non raccordé au réseau public de collecte (égouts). Le terme d'assainissement non collectif, ou autonome, désigne généralement l'ensemble des étapes de traitement permettant d'épurer les eaux usées d'une habitation individuelle, unifamiliale, en principe sur la parcelle portant l'habitation, sans transport des eaux usées.
