Location of main activity


The long term vision of this programme is that urban Tamil Nadu will be poised to becoming a fully sanitised and healthy state, substantially eliminating open defecation, achieving improvements in services through the entire sanitation value chain, and able to safely dispose an increasing proportion of its human excreta, and re-use/ recover resources therefrom.

The goal is to demonstrate measurable improvements along the entire urban sanitation chain in Tamil Nadu, and strengthen institutional capacities for promoting inclusive sanitation with a focus on improved access for the urban poor

Indian Institute for Human Settlements

The IIHS provides advisory services to national and state governments, public, parastatal municipal agencies, international agencies and private firms in the broad area of human settlements and urbanisation, with a view to providing cutting edge and integrated solutions to some of India's emerging urban development challenges. It also serves on a number of national and state level government committees and policy fora. These engagements have considerably influenced policy process and implementation in sectors like water and sanitation, housing, climate change and land records, among others. Current IIHS practice on the environmental services focuses on a range of issues such as water supply, sanitation and integrated basic environmental services. Practitioners have also been exploring notions of common property and shared natural resources, environmental governance, issues of water supply and management, and the provision of water and sanitation services to urban populations, especially the urban poor. Projects have also included the evaluations of national and state programmes and policies from a sustainability perspective, as well as large scale implementation support partnerships. This area of practice is directly aligned with the School of Urban Systems and Infrastructure, and the School of Human Development.
