Rapid urbanisation has inevitably increased pressure on urban infrastructure and services, much of which have not sustainably been provided to muddle through with rapid urban growth; thus, resulting to poor urban service delivery including uncollected solid waste in most urban locations in developing countries. The city of Dar es Salaam including its three municipalities has no exception. On one hand, solid waste has high ability of threatening and degrading environmental resources e.g. polluting air through noxious smell, polluting surface and underground water through seepage of deposited and decomposed wastes if not properly managed and above all deterring investments in settlements. On the other hand, waste collection and disposal are very challenging elements in waste management. These issues are also critical in Dar es Salaam, due to increased waste generation and low collection capacity of the actors involved. In the year 2005, about eighty per cent of the solid waste generated in Dar es Salaam was uncollected. Although the situation had improved a bit by 2007, solid waste management is still a problem in Dar es Salaam due to many factors that include: lack of information on the extent of solid waste generated, inadequate data on the number of households generating the waste, poor cost recovery due to non-payment of refuse collection fees and poor collection system within settlements. Geo Information System (GIS) is a tool that can provide spatial and non spatial information for urban planning and management. It can also link this data for various uses. Therefore, this paper examines and brings knowledge on how GIS can assist in increasing information and efficiency of solid waste collection system in an urban settlement in a developing country such as Tanzania. Sinza neighbourhood in Kinondoni Municipality in Dar es Salaam City is taken as a case for knowledge sharing.
