The Tamil Nadu government has initiated an environmental audit of 28 urban water and sewerage projects, alongside a study on manual scavenging practices.
Chennai, India Jul 19, 2026 ALN: The Tamil Nadu government has taken a significant step towards enhancing urban infrastructure by initiating an independent environmental and social audit of 28 major water supply and underground sewerage projects. These projects are being implemented across 21 urban local bodies and are part of a broader initiative aimed at urban infrastructure reforms. The government's commitment to improving urban living conditions and ensuring sustainable development is evident in this initiative, which seeks to address the pressing issues of water supply and sewage management in the state.
These projects fall under the Tamil Nadu Climate Resilient Urban Development Programme (TNCRUDP), a comprehensive six-year initiative supported by the World Bank, which runs from 2024 to 2030. The programme was approved by the World Bank in December 2023 and aims to strengthen water security, enhance climate resilience, and modernize urban governance throughout the state. The TNCRUDP is particularly significant in the context of climate change, as it addresses the vulnerabilities faced by urban areas in Tamil Nadu, which are increasingly impacted by extreme weather events such as floods and droughts. By focusing on sustainable urban development, the programme aims to create resilient cities that can effectively manage their water resources while minimizing environmental degradation.
Tamil Nadu Urban Infrastructure Financial Services Ltd (TNUIFSL), the agency responsible for implementing these projects, has issued a call for bids to appoint an independent consultant who will conduct the audit. This audit will assess compliance with the environmental and social safeguards that are mandated under the programme during the execution of projects in the fiscal year 2024-25. The involvement of an independent consultant underscores the government's commitment to transparency and accountability in the implementation of these projects, ensuring that they meet the necessary environmental and social standards.
The audit will encompass four categories of infrastructure works. Firstly, it includes seven underground sewerage schemes that focus solely on sewer collection networks in cities such as Salem, Thoothukudi, Karaikudi, Tiruvarur, Krishnagiri, Theni, and Avadi. These projects are critical for improving sanitation and public health in these urban areas, as they aim to provide efficient and effective sewage management systems that can handle the growing urban population's needs.
Secondly, another seven projects will involve underground sewerage systems equipped with sewage treatment plants in locations including Tiruvannamalai, Pudukkottai, Namakkal, Dharmapuri, Cuddalore, Dindigul, and Kancheepuram. The establishment of sewage treatment plants is essential for treating wastewater before it is discharged into the environment, thereby reducing pollution and protecting water bodies from contamination. This aspect of the audit will ensure that the treatment facilities are designed and operated in compliance with environmental regulations and standards.
Additionally, the review will cover a city-wide water supply improvement project in Kancheepuram, along with 13 pilot projects aimed at providing round-the-clock water supply in various cities including Avadi, Karaikudi, Pudukkottai, Tiruchy, Thoothukudi, Tirunelveli, Erode, Vellore, Cuddalore, Dindigul, Tambaram, Nagercoil, and Rajapalayam. The focus on improving water supply is particularly relevant given the increasing demand for water in urban areas, driven by population growth and economic development. The pilot projects are designed to demonstrate effective strategies for ensuring a reliable and sustainable water supply, which is a critical component of urban infrastructure.
The consultant tasked with this audit will categorize findings into four distinct areas: compliance, non-compliance, best practices, and areas that require improvement. This structured approach will provide a comprehensive overview of the projects' performance and highlight both successes and challenges encountered during implementation. In cases where deficiencies are identified, the consultant will be required to revisit the projects after corrective measures have been implemented to verify compliance before submitting the final report. This iterative process of evaluation and improvement is essential for ensuring that the projects not only meet their immediate goals but also contribute to long-term sustainability and resilience.
A critical component of this assignment is a thorough study on manual scavenging and hazardous sewer cleaning practices. This study will investigate the policy and legal framework governing sewer maintenance, pinpoint gaps in implementation by urban local bodies, analyze scenarios necessitating hazardous sewer entry, and review past incidents through field visits and consultations with officials, contractors, and sanitation workers. Manual scavenging, a practice that has been a contentious issue in India, poses significant health risks to workers and raises serious ethical concerns. By addressing this issue, the audit aims to promote safer and more dignified working conditions for sanitation workers, which is a crucial aspect of social equity and justice.
Furthermore, the study will evaluate existing standard operating procedures, training programs, and safety practices across the sewage management chain to ensure comprehensive oversight and improvement. Proper training and adherence to safety protocols are vital for minimizing risks associated with sewer maintenance and ensuring the health and safety of workers. The findings from this evaluation will inform future policies and practices aimed at enhancing the safety and efficiency of urban sanitation services.
The three-month assignment will commence with a preliminary compliance report due within two weeks, followed by a draft report for review by the implementing agencies and the World Bank prior to the submission of the final report. This timeline reflects the urgency of the issues at hand and the government's commitment to expediting the audit process to ensure timely interventions where necessary.
This audit is part of the World Bank’s Programme-for-Results financing model, which necessitates independent verification of commitments outlined in the Programme Action Plan, developed after the Environmental and Social Systems Assessment. This model emphasizes results and accountability, ensuring that funds are allocated effectively and that projects deliver tangible benefits to communities. The involvement of the World Bank not only provides financial support but also brings in international best practices and expertise in urban development and environmental management.
Overall, the Tamil Nadu government's initiative to conduct an environmental and social audit of urban water and sewerage projects marks a significant advancement in the state's urban development strategy. By prioritizing environmental sustainability and social equity, the government aims to create a more resilient urban infrastructure that can effectively meet the needs of its growing population while safeguarding the environment. The successful implementation of these projects and the insights gained from the audit will contribute to shaping future urban policies and practices in Tamil Nadu, ultimately leading to improved quality of life for its residents.
