The Tamil Nadu Urban Flagship Investment Program (TNUFIP) will advance India’s national urban flagship programs to develop priority urban and environmental infrastructure in ten cities located within strategic industrial corridors of Tamil Nadu (the State), including those within the East Coast Economic Corridor (ECEC), to enhance environmental sustainability, climate resilience, and liveability. It will also strengthen the capacity of state and local institutions and improve urban governance. TNUFIP is aligned with the following impacts: (i) universal access to basic water and sanitation services achieved, (ii) world-class cities and industrial corridors across the State developed, and (iii) water security and reducing vulnerability to climate change in urban areas and enhancing share of renewable energy achieved. TNUFIP will have the following outcomes: liveability and climate resilience in at least 10 cities in priority industrial corridors enhanced. 2. The TNUFIP is structured under three outputs: (i) climate-resilient sewage collection and treatment, and drainage systems developed in at least 8 cities; (ii) water supply systems in at least 5 cities improved with smart features; and (iii) institutional capacity, public awareness, and urban governance strengthened. TNUFIP is implemented over an 8-year period beginning in 2018, and will be funded by Asian Development Bank (ADB). via its multi-tranche financing facility (MFF). 3. The Subproject. Chennai is the fourth largest Metropolitan city in India. In 2011, Chennai City has been expanded to 426 square kilometer (km2) from 176 km2 by the annexure of 42 adjacent Urban Local Bodies. The entire erstwhile Chennai city had been provided with water supply and sewerage facilities. Hence, CMWSSB has proposed to provide water supply and sewerage facilities in all the 42 added areas of Chennai city on par with erstwhile Chennai City. In the expanded Chennai city, at present water supply scheme has been completed in 13 added areas and in 23 added areas water supply schemes are under implementation. For the balance 6 added areas DPR for water supply scheme has been prepared. Now, under the TNUFIP, water supply schemes are being implemented in 4 added areas namely Mathur, Madipakkam, Jalladampettai and Uthandi having an area extent of 2.98 km2, 3.40 km2, 2.28 km2 and 3.41 km2 respectively totalling to 12.07 km2. The total road infrastructures available in the above four locations is around 219 km. The components of proposed water supply scheme includes: (i) water distribution station (WDS) at Mathur Zone II, which include 200 kl (kilolitre) capacity underground tank (UGT), and 1200 kl capacity overhead tank (OHT), and a pump house, (ii)WDS at Madipakkam, which include 900 kl UGT, 5,000 kl OHT and a pump house, (iii) WDS at Jalladampettai, which include 200 kl UGT, 1,300 kl OHT, and a pump house, (iv) WDS at Uthandi, which include 200 kl UGT, 800 kl OHT, and a pump house, (v) distribution network of total length 223.09 km of ductile iron (DI) pipes of diameter 100-900 mm covering all four water supply schemes, and (vi) 23,716 nos. house service connections. 4. Since it is proposed to source treated water from the existing water treatment plants, subproject proposals do not include source or treatment infrastructure. The subproject will essentially tap treated water from the existing water mains carrying water from the treatment plants, and supply to the subproject areas. 5.
