Technical assistance to government of Tamil Nadu to establish Technical Support Unit (TSU) for urban sanitation (Phase I)

2015 - 2017 • Indian Institute for Human Settlements (iihs)


To provide public health benefits and city-wide sanitation improvements for urban populations in Tamil Nadu by demonstrating innovations in two model urban locations



Technical assistance to establish Technical Support Unit (TSU) for urban sanitation at the Department of Municipal Administration and Drinking Water System.

The key functions of the unit will include program management, demand generation, MLE, private sector engagement, technology identification and capacity building for scaling up successful approaches across the state. The TSU will also support to establish two model cities that demonstrate entire sanitation value chain in urban centers.

In order to achieve the Sanitation Mission of Tamil Nadu, the Bill and Melinda Gates Foundation (BMGF) is supporting the GoTN by setting up a Technical Support Unit (TSU) within the Municipal Administration and Water Supply (MAWS) Department. The TSU implements the TNUSSP, a state-wide programme to make improvements along the entire urban sanitation chain in their planning, implementation and monitoring processes in Tamil Nadu. An Advisory Committee in MAWS Department guides the TSU, that works closely with State Agencies, ULBs, private enterprise and communities, to enable considerable experimentation on ground and testing of innovations especially in two model cities, while assisting State-level scaling up.
