First water supply project in the Public Private Partnership framework

New Tirupur Area Development Corporation Limited (NTADCL) has been established as a special purpose vehicle for development and implementation of the Tirupur Water Supply and Sewerage Project. NTADCL is promoted by Tamilnadu Water Investment Company Limited (TWIC), Infrastructure Leasing and Financial Services Limited and Tirupur Exporters Association to implement the first Water Supply and Sewage project under the public-private partnership in the country. It is the first water supply project in India financed commercially on a limited recourse basis. A Concession Agreement has been signed in 2000 between Govt of Tamilnadu, NTADCL and Tirupur Municipality(TM)

The Project foundation was laid on 20th June 2002 by Honorable Chief Minister of Tamilnadu. The Project was inaugurated on February 2006.

Under the project, facilities have been constructed to abstract, treat and supply 185 MLD (million litres of water per day) from the confluence of river Cauvery and Bhavani. The water is being supplied to the dyeing, bleaching and other industries and domestic consumers in and around Tirupur. The domestic consumers are of Tirupur Municipality(TM), three Town Panchayats and fifteen Village Panchayats to cater around 11 Lakh beneficiaries. This provides umbrella coverage for the entire water supply requirements of Tirupur Planning area spread over 225 SqKm.

In addition, water supply is being provided to enroute habitations in five wayside unions through Tamilnadu Water Supply and Drainage Board (TWAD). The water supply project has been completed within stipulated time frame and budgeted cost as per prescribed standard. NTADCL has commenced water supply to all consumers (industrial and domestic) since 2005 on continuous basis. The Project also includes about 120 KM length of sewer collection system with Four Sewage Pumping Stations (SPS) and a 15 MLD Sewage Treatment Plant (STP) expandable to 30 MLD. The sewage system has been commissioned in the year 2008.
