The Asian Development Bank approved a $139.55 million loan on 30 October 2026 for the Puducherry Integrated Urban Livability Improvement Project (PIULIP). The project will upgrade water supply, sewerage, public spaces and municipal governance in Puducherry and is expected to benefit more than 320,000 people. It is the first time the Bank has taken up a project in the Union Territory of Puducherry.
What Is the Puducherry Integrated Urban Livability Improvement Project?
The Puducherry Integrated Urban Livability Improvement Project, shortened to PIULIP, is a city infrastructure programme of the Government of Puducherry supported by the Asian Development Bank. The total project cost is about $199.38 million. Of this, the Bank will provide $139.55 million as a loan from its ordinary capital resources, and the central and Union Territory governments will provide the remaining funds as counterpart support.
The Public Works Department (PWD) of Puducherry is the executing agency. A dedicated project management unit will carry out day to day work. The project will run till 30 April 2033 as per current project documents. It is designed as a first phase of a longer partnership, with additional financing and a second phase under consideration.
The project has three linked outputs. The first is climate resilient water supply and sanitation. The second is rejuvenation of urban public spaces. The third is stronger institutional capacity and financial sustainability of urban local bodies. Together, these outputs aim to improve daily services, make the city more attractive for visitors and investors, and protect growth from climate risks.
How Will the Loan Improve Water Supply and Sanitation in Puducherry?
Water supply and sewerage form the largest part of the project. Puducherry depends heavily on groundwater, and coastal salinity raises the level of dissolved salts in wells. Old pipes leak and many areas still lack underground sewers. The project tackles both source security and network losses.
On the water side, the plan includes upgrading 100 km of existing supply network and laying 80 km of new pipelines. The government will build new overhead service reservoirs to store treated water and maintain pressure. It will create district metered areas, which are small zones with bulk meters that measure inflow and outflow to find leaks fast and cut non revenue water. Non revenue water is treated water that is lost to leaks or illegal connections before it reaches paying users.
To strengthen sources, the project will set up brackish water reverse osmosis plants. Brackish water is groundwater with high salt content, and reverse osmosis is a filtration process that pushes water through a fine membrane to remove salts. Project documents provide for three such plants of 1 MLD each in Puducherry, adding about 3 MLD of safe drinking water. MLD means million litres per day. The project also targets piped connections with meters for about 20,000 households.
| Water and Sewerage Component | Scale Announced |
|---|---|
| Existing water network to be upgraded | 100 km |
| New water pipelines to be laid | 80 km |
| New brackish water treatment capacity | 3 MLD from three 1 MLD plants |
| New underground sewer network | 270 km |
| Existing sewer network to be rehabilitated | 80 km |
| New sewage treatment plant capacity | 50 MLD |
On the sanitation side, the project will lay 270 km of new underground sewers in unsewered zones, including zones 11 to 14 of Puducherry city, and rehabilitate 80 km of old sewers in areas such as Muthialpet, Orleanpet and Rainbow Nagar. A new 50 MLD sewage treatment plant (STP) will treat the additional flow. An STP cleans used water so it can be safely released or reused. The plant will use a digital supervision system to track performance. Untreated sewage now flows into drains, ponds and the Ariyankuppam and Gingee rivers and the Thengaithittu estuary. By collecting and treating it, the project aims to cut waterborne disease and protect groundwater.
Why Puducherry Needs Better Urban Services Now
About 68 percent of the population of Puducherry lives in urban areas. The population of the Union Territory is about 1.8 million as per recent Bank assessments, with the 2011 Census count at 12.47 lakh. The Territory draws more than 2.3 million tourists each year because of its French colonial streets, beaches such as Promenade and Eden, the Sri Aurobindo Ashram and nearby Auroville. Rapid growth, tourist pressure and climate risks have strained drinking water, sewers and drains.
Puducherry is a low lying coastal city. Heavy rain causes flooding, and dry months increase dependence on saline groundwater. Poor drainage and broken footpaths raise accident risks and make the main commercial streets congested. These gaps reduce the city’s appeal as an investment and tourism destination. The Bank’s country director for India, Mio Oka, said the project will help turn Puducherry into a more livable, tourism friendly and resilient growth hub and support the goal of making Indian cities engines of economic growth.
Urban livability means how easy, safe and healthy daily life is in a city. In India it is tracked through tools such as the Ease of Living Index released by the Ministry of Housing and Urban Affairs. The index scores cities on quality of life, economic ability and sustainability. Safe water, clean drains, treated sewage and walkable streets directly improve such scores.
How Public Spaces and Municipal Finances Will Be Strengthened
The project will build 4.5 km of pedestrian walkways that are accessible to persons with disabilities. The first stretches are planned on MG Road and Mission Street, busy heritage and market corridors in the Boulevard Town. The walkways will have gender responsive and inclusive design, with safe crossings, lighting and space for vendors without blocking foot traffic. Storm drains along these stretches will be lined with concrete and stabilised to prevent flooding and road damage during extreme rain.
The third part of the project focuses on how the city manages money and services. The municipal administration will improve revenue collection, upgrade financial management systems and launch a digital municipal service platform. This platform will allow better billing, complaint handling and asset tracking. The government will also prepare integrated plans for water security and inclusive sanitation so that poor households and women headed households get metered connections on priority. Project documents aim for at least 35 percent representation of women in leadership or technical roles in new water user associations.
What Is the Asian Development Bank and How Does It Work?
The Asian Development Bank is a multilateral development bank that lends for social and economic development in Asia and the Pacific. Multilateral means it is owned by many countries, not by one government or private company. It was established on 19 December 1966 and is headquartered at 6 ADB Avenue in Mandaluyong City, Metro Manila, Philippines. It has 69 member countries, of which 50 are from Asia and the Pacific. India is a founding member.
The Bank gives loans, grants and technical advice to governments for infrastructure, water, energy, transport, health and education. Its ordinary capital resources are its main lending pool funded by member contributions and market borrowing. In India, the Bank supports urban transformation through city level projects and national programmes such as the Urban Challenge Fund. It also funds metro rail, river rejuvenation and state road projects. The current President is Masato Kanda of Japan, who assumed office on 24 February 2025 as the 11th President. The India Resident Mission is located in New Delhi and handles project design and supervision with central and state agencies.
The Puducherry loan matters because ADB projects in a state or Union Territory often bring stricter design, safeguard and monitoring standards. Bids follow the Bank’s procurement rules, sewers need environmental assessments, and treatment plants need long operation periods. For example, the new STP will be built on a design, build and operate model with about 10 years of operation by the contractor.
Where Is Puducherry Located and Why Does Its Spread Matter?
Puducherry is not a state. It is a Union Territory with a legislature, which means it has an elected assembly but the central government retains greater control than in a full state. It is not part of any state. It consists of four small, separated coastal regions. Puducherry and Karaikal lie as enclaves within Tamil Nadu on the east coast, Yanam lies within Andhra Pradesh, and Mahe lies within Kerala on the west coast. Puducherry city, about 162 km south of Chennai on the Coromandel Coast of the Bay of Bengal, is the capital.
The total area is about 479 to 493 sq km across the four regions, with the Puducherry region alone covering about 294 sq km. The main languages are Tamil, Telugu and Malayalam, and English and French are also widely used because of the Territory’s history as a former French colony. Puducherry was transferred to India in 1954 and became a Union Territory in 1963.
This scattered geography shapes the project. Most physical works under PIULIP are located in the Puducherry region, where pressure from residents and tourists is highest. A programme approach is planned, so lessons from this phase can later support Karaikal, Mahe and Yanam. Better water and sewerage in the main city will also protect beaches, rivers and groundwater that sustain fishing, farming and tourism across the coast.
