TNUSSP supports the GoTN and cities in making improvements along the entire urban sanitation value chain.

The IIHS-led Tamil Nadu Urban Sanitation Support Programme (TNUSSP) supports the Government of Tamil Nadu (GoTN) and cities in making improvements along the entire urban sanitation value chain. The TNUSSP is being implemented by a consortium of organisations led by the Indian Institute for Human Settlements (IIHS).

The Regional Centre for Urban & Environmental Studies Lucknow, in collaboration with the National Institute of Urban Affairs (NIUA), conducted a two-day training programme on Gender, Equity, Disability, and Social Inclusion (GEDSI) in Sanitation on 21–22 July 2026 at the RCUES campus, Lucknow. The programme brought together 27 Executive Officers and Junior Engineers from Urban Local Bodies (ULBs) across Uttar Pradesh. It aimed to strengthen participants' capacities to apply a GEDSI lens in sanitation planning and service delivery.

Abhilaasha Nagarajan (Consultant–Practice), Indian Institute for Human Settlements (IIHS), facilitated sessions on fiscal innovations such as gender budgeting; the intersections between gender-based violence and WASH; creating safe and inclusive workplaces, particularly for sanitation workers; and approaches to planning citywide inclusive sanitation.

As part of the programme, participants also visited the CSC Airport Metro Station and the Integrated Command and Control Centre (ICCC) to gain practical insights into accessible urban infrastructure, universal accessibility features, gender-responsive public services, and digital governance systems that support inclusive service delivery.

How can cities build inclusive WASH systems if the people and places they serve remain invisible? At , Indian Institute for Human Settlements (IIHS) moderated a policy dialogue From Informal Settlements to City Systems.

WASHathon 2026 was a two-day national event that combined an innovation hackathon and multi- stakeholder policy dialogues to develop and advance inclusive WASH solutions for waste picker
communities by bridging the gap between informal settlements, workplaces, urban governance, and sustainable service delivery.

At the WASHATHON 2026 – WASH Innovation for Waste Picker Communities: Bridging the Settlement–Workplace Gap by WaterAid India in Bengaluru on 25-26 June, IIHS curated the policy
dialogue From Informal Settlements to City Systems.

Organised under WaterAid India's Saamuhika Shakti initiative in Bengaluru, which brought together government, civil society, academia, the private sector, and waste picker communities to co-create inclusive, sustainable urban WASH solutions that improve living and working conditions for informal waste workers.

Moderated by Niladri Chakraborti, Senior Lead- Practice, IIHS, the hour-long session centred around the key question- Why do cities repeatedly fail to deliver inclusive WASH services despite decades of experience, and what systemic changes are needed to integrate informal settlements and waste picker communities into citywide WASH governance, planning, and financing? Kesavan Nair, Kerala Solid Waste Management Project, called for cities to "break the chain" by recognising waste pickers as essential urban service providers. Drawing on Kerala's experience, he proposed elevating the designation of waste pickers to the status accorded to street vendors, with formal identity, institutional recognition, and access to social protection. Anand Jagtap, former Officer on Special Duty, Municipal Corporation of Greater Mumbai, reminded us that there are "no 'one type' of slums," arguing that rigid legal definitions often hinder universal service delivery and that WASH concerns must be better integrated into city policy. Girija Ramakrishna, CDD India, stressed that every settlement requires context-specific baseline assessments, continuous engagement with communities, and sustainable operation and maintenance models. Priya Nath,
WaterAid UK, urged participants to recognise that the challenge is not one of "overlooking" communities, but of systemic injustice, making gender and social inclusion central to the design of
WASH interventions.

The discussion reinforced a shared message: inclusive urban WASH is not simply about extending infrastructure—it is about transforming governance, recognising informal workers, and placing communities at the heart of planning and service delivery.

Indian Institute for Human Settlements (IIHS), leading the Tamil Nadu Urban Sanitation Support Programme (TNUSSP), organised a two-day training on ‘Occupational Safety and Health for Sanitation Workers Engaged in Septic Tanks Desludging’, in collaboration with the Municipal Administration and Water Supply Department (MAWS) TN_maws , Government of Tamil Nadu, and the Regional Labour Institute (RLI), Directorate General Factory Advice Service and Labour Institutes, Ministry of Labour and Employment, Government of India. The programme brought together Sanitary Inspectors, Supervisors, and De-Sludging Operators from 20 Municipalities in the Chengalpattu region of Tamil Nadu.

Sanitary Inspectors and Supervisors play a critical decision-making role in planning and implementing septic tank and sewer cleaning operations, activities that involve multiple workplace hazards, including confined space entry. The training forms part of TNUSSP’s decade-long engagement to strengthen occupational safety and health (OSH) practices in sanitation work.

A total of 51 participants engaged in classroom sessions, field demonstrations, and simulation exercises to build a stronger understanding of occupational safety. Key themes included vehicle and site safety, hazardous process management, with particular emphasis on atmospheric gas measurement and confined space safety. Cross-cutting discussions addressed occupational and mental health, as well as safety communication.

The sessions were delivered by a multidisciplinary technical team comprising representatives from the Regional Labour Institute; the Directorate of Medical and Rural Health Services (DMS), Government of Tamil Nadu; Tamil Nadu Fire & Rescue Services Department; and subject experts. Anamika Ramesh, I.A.S., Joint Commissioner of Municipal Administration, Government of Tamil Nadu, attended the closing session and encouraged participants to translate their learnings into safer on-ground practices.

The sessions drew from a needs assessment study IIHS conducted in 2018 across two Indian cities, underscoring the importance of moving beyond Personal Protective Equipment (PPE) and ensuring sanitation workers’ participation in safety-related decision-making. In 2022, TNUSSP developed a First Aid Training Manual for De-sludging Workers focused on workplace emergency management and accident prevention. Since 2023, TNUSSP has worked with RLI and the Directorate of Industrial Safety and Hygiene (DISH) to develop a comprehensive OSH Manual for sanitation workers engaged in de-sludging; the present training drew directly on these principles.

On 19 Sept 2025, the WASH Club met for its 2nd monthly session with 24 student members, supported by Indian Institute for Human Settlements (IIHS) and HCLFoundation.

This month’s focus was Handwashing and World Cleanup Day. Students learnt through a glitter experiment, video, and live demo how important proper handwashing is. They will now create awareness charts in classrooms and remind peers before meals.

Ahead of World Cleanup Day, children also took part in a game on keeping surroundings clean and discussed how they can be role models in their community.

The students have committed to share these lessons with their families and neighbourhoods – showing how small actions can lead to a cleaner, healthier future.
