Planning approaches for sanitation systems in peri-urban areas: a case study from Tanzania

The planning and improvement of sanitation systems represents a critical problem for low-income countries, in particular in rapid growing peri-urban areas. This paper illustrates the assessment of the Community-Led Urban Environmental Sanitation (CLUES) and the Sanitation Safety Planning (SSP) approaches, tested for the design of an improved sanitation system in peri-urban areas of Iringa Municipality, in Tanzania. The application in field of the two approaches permitted to evidence and analyse their strengths and weaknesses, and possibilities to increase their potentials with an integrated use. The experience, applied to a case study, aims to be an example of application for practitioners dealing with sanitation planning in context showing similar characteristics.
