TACKLING THE CHALLENGES OF FULL PIT LATRINES – Volume 3: The development of pit emptying technologies
Over two million VIPs and other on-site sanitation systems have been built by the South African
government since 1994. A backlog of households lacking basic sanitation still remains, however, and many municipalities are still focussed on meeting this need and have not yet turned their attention to the question of what they will do when the systems they have already built reach capacity. This is expected to happen in the next few years, resulting in an overwhelming demand for pits to be emptied. Without funds, policies, tools or procedures in place to manage the emptying of pits and disposal of sludge when this happens, many WSAs around the country may soon be facing a crisis. This report presents the design, development and testing of a number of prototypes of portable pit emptying technologies that were developed as part of Water Research Commission research project K5/1745. It is preceded by two other reports in the Tackling the challenges of full pits series:
Volume 1: Understanding sludge accumulation in VIPs and strategies for emptying full pits.
Volume 2: How fast do pit toilets fill up? A scientific understanding of sludge build up and accumulation in pit latrines
