 Hogenakkal Water Supply & Fluorosis Mitigation Project in Dharmapuri and Krishnagiri District

The Hogenakkal Water Supply & Fluorosis Mitigation Project have been implemented with the objective of providing potable water supply to Dharmapuri and Krishnagiri Districts in Tamil Nadu, which comprises of 3 Municipalities, 17 Town Panchayats and 7639 Rural Habitations.

Both Dharmapuri and Krishnagiri Districts are drought prone areas and the ground water sources of these two districts have excess fluoride above the permissible level of 1.50 mg/lr. with other quality problems, due to Nitrate, Hardness and Iron. More than 66 % sources are not potable due to single & multiple parameters and 57% habitations in Dharmapuri and 58% in Krishnagiri District have high fluoride level in ground water. The population in Dharmapuri and Krishnagiri Districts are affected by fluoride leading to Dental, Skeletal and Non-skeletal Fluorosis. Hence as a permanent solution, it becomes imperative to provide sustainable and reliable water supply with appropriate Fluorosis mitigation measures.

 Unique Features of the Hogenakkal Water Supply & Fluorosis Mitigation Project:

• The HWS & FM Project was first of its kind, in which a comprehensive objective was adopted providing sustainable and protected drinking water to the entire population of Dharmapuri and Krishnagiri districts along with Fluorosis mitigation measures for all the afflicted population through medical interventions as well as Capacity Development of Local Bodies in efficient management of Operations & Maintenance.

• The Intake structures are designed & located in such a way that even during the lowest flow in the river Cauvery, the designed quantity of 160 MLD water flows into intake well.

• Full scale Water Treatment Plant of 160 MLD in 12 acres of land at a location locally known as ‘Yanai Pallam’ within the forest.

• Flat Bottom Sludge Blanket Clarifier in place of conventional Clari-flocculator to remove of all impurities of raw water without need of any electricity.

• The entire quantity of wash waster of filter bed as well as sludge water from clarifier are recovered and recycled.

• Un-interrupted power supply through dedicated dual power supply to Intake Works, Water Treatment Plant and Booster Pumping Station.

• The treated water distributed from a 240 lakh litres capacity Master Balancing Reservoir at a distance of 11.15 km and at 200m higher elevation than treatment plant, utilizing the elevation to supply water by gravity wherever feasible and thereby making the project ‘energy efficient’.

• The optimum and efficient operation & maintenance is ensured through installation of SCADA system with telecommunication & satellite connection.

• All tribal habitations at very higher altitudes covered with water supply, at high installation costs by pumping to more than 1000m height.(+MSL 1245.186 M)

• Another remarkable feature is the water facilities made to Elephants and other animals through water troughs in the Thally and Kelamangalam reserve forest areas.
