A small pit emptying machine: an appropriate solution for a Nairobi slum.
This article describes the results of the trial period of a pedestrian-controlled pit emptying machine. This 'vacutug' has been tested for UNCHS (Habitat) in a low-income settlement in Nairobi, Kenya, through a local NGO. The trial confirmed the viability of the principle of the vacutug as the machine has been in operation for two and a half years. Repairs have been made locally out of income from the service, spare parts can be obtained and demand for the service is high. Although the cost of the service has already been raised, demand has not been reduced. The technical improvements which need to be made can be incorporated in the design, and the next batch of machines is being constructed for further trials. Management of the service is critical for financial sustainability and even during the trial of the technology, the management aspects have been the most difficult of the service.
