The Credit was finally closed on December 31, 1994, although the original Credit closing date was June 30, 1990. The project suffered delays. It was restructured, with the approval of the Board, on January 7, 1991 to include additional components and with an extension of the closing date to November 30, 1992. Also at that time the disbursement percentage was increased by the Bank. After two more extensions the restructured project was substantially complete by the final revised Credit closing date and was fully disbursed by March 1, 1995. The ICR was prepared by Messrs. G.V. Abhyankar of the Bank's Resident Mission in New Delhi, A. Saravanapavan (Consultant) and Karl Kleiner (Task Manager) of the Agriculture and Water Operations Division, Country Department 2, South Asia Region. The ICR was reviewed by Mr. Shawki Barghouti, Chief, Agriculture and Water Operations Division, Country Department 2, South Asia Region, and Mr. Christopher Couzens, Project Advisor (Acting). The Borrower provided an independent evaluation which is included as an appendix to the ICR. The preparation of this ICR began during the Bank's final supervision mission in November 1994. It is based on the material from the project file and mission findings. The Borrower contributed to the ICR by providing data, views on the project outcome and the independent evaluation. ii IMPLEMENTATION COMPLETION REPORT INDIA TAMIL NADU WATER SUPPLY AND SANITATION PROJECT (CREDIT IDA 1454/SF 12 IN) Evaluation Summary Project Objectives 1. The broad aims of the project were to improve water supply and sanitation services in specific urban areas, support institutional and financial strengthening of the sector institutions and develop a water resource management strategy for the water-scarce State of Tamil Nadu in India. This was the first Bank Group-financed statewide water supply and sanitation project in the State, following similar projects in five other Indian states. The project was expected to benefit over 4 million of the urban population in the State. 2. The specific objectives and the scope of the project were to: (a) improve water supply in three large urban towns (Coimbatore, Madurai and Salem) and provide safe water supply to a number of smaller towns and rural areas without these facilities; (b) provide proper low-cost sanitation (LCS) facilities to selected urban communities to improve public health standards; (c) assist the Government of Tamil Nadu (GOTN) and the implementing agency, the Tamil Nadu Water Supply and Drainage Board (TWAD), in developing water resources management strategies aimed at achieving overall economies in providing drinking water; (d) enable low-income groups to connect to the systems, or alternatively to provide adequate standpost facilities; (e) strengthen TWAD's institutional, managerial and financial practices through training and technical assistance; and, (f) assist urban local bodies in improving their resource base for proper operation and maintenance of installed facilities. 3. The project was restructured on January 7, 1991 to expand water supply service coverage by adding water supply schemes for 6 medium-sized towns and several drought affected rural communities, LCS units in additional small towns and a sector plan study. Implementation Experience and Results 4. The original project implementation schedule (1985-90) was not adhered to, and the delays were extensive. Project extensions totaling more than 4 years were granted. There were four main reasons for the delays: (a) TWAD was slow to prepare final designs (and undertook two major design changes which were time consuming), initiate bid invitations and make awards; (b) unsatisfactory performance by one major pipeline contractor that caused serious problems; (c) poor project management by TWAD, at least in the initial years; and, (d) the original implementation schedules were unrealistic. For the Coimbatore water supply scheme, there was a delay of two years because GOI environmental clearance for using a forest reserve was not granted,
