The Scheme is aimed at providing potable Water Supply to Dharmapuri and Krishnagiri Districts in Tamil Nadu, which comprises of 3 Municipalities, 17 Town Panchayat and 6,755 rural habitations in 18 Panchayat Unions apart from mitigating the fluorosis. At present Water Supply is provided through various Combined Water Supply Schemes and Individual Power Pump schemes using local sources to the people of these areas. The water quality analysis reports exhibit concentration of fluoride in ground water in many parts of these Districts ranging from 1.5 mg/l to 12.4 mg/l which is in excess to the permissible limit of 1.5 mg/l as specified in Central Public Health and Environmental Engineering Organization (CPHEEO) Manual. Due to the consumption of fluoride contaminated water over a prolonged period, people in the above two Districts are suffering from Skeletal Fluorosis, dental Fluorosis, non-skeletal manifestation or combination of the above.

 Administrative Sanction:

Both the Dharmapuri and Krishnagiri Districts are also drought prone areas. The drinking water supply as well as its management poses problems during summer and drought periods. Hence a permanent solution is necessary to mitigate Fluorosis problem in the water starved Districts for providing sustainable and reliable water supply. The Government of Tamil Nadu sanctioned the Hogenakkal Water Supply and Fluorosis Mitigation Project with a perennial source River Cauvery in G.O Ms. No 26 dt.25.02.2008 at a total cost of Rs.1, 334.00 Crore to install and Rs.51.65 Crore to maintain annually. Subsequently the Government of Tamil Nadu in G.O.Ms.No.19 dt.29.01.2010 have accorded revised administrative sanction for this project at a total cost of Rs.1, 928.80 Crore to install and Rs. 63.67 Crore to maintain annually taking into account the change of pipe material, increase in number of Booster pumping station, price escalation etc. This Project will cater to the ever-increasing Water Supply demand of both the Districts and benefit the present population of 29.80 lakh.

A Consortium comprising of M/s. Nippon Koei Co. Ltd. Japan , M/s AECom Metcalf Eddy Hong Hong & M/S STC Mumbai has been employed as Project Management Consultant (PMC) for this Project and the Consultancy firm has commenced the work since 3rd October 2008.
