This note reviews the criteria for on-site sanitation, preferred types of pit latrine and the need for mechanised options for pit emptying. The likely composition of pit sludge is described and a method of categorising a particular sludge is included so that a suction tanker can be specified, capable of handling that sludge. An indication is given of likely pit emptying costs for a BREVAC suction tanker in an organised emptying service.
