As a result of inappropriate planning and management, urban infrastructure has not been able to keep up with the demands of the growing urban population. Poor sanitation and its contribution to the spread of diseases and pollution cannot be neglected. It has been made evident that there is a lack of capacity and effective resources required to adequately address the needs of decision makers in the Indian context. There is thus a need to develop a broad resource base for decision makers which will enable them to understand the sanitation needs of a city as well as provide them with a range of sanitation system options which can serve these needs. This report is a prelude to the development of a Proof-of-Concept (PoC) decision-support tool that will aid cities in providing cost-effective, inclusive and sustainable sanitation options for all, with particular emphasis on the urban poor.
