For the town of Bharatpur in Rajasthan, there is no natural source of water. Drinking water to the town and its surroundings was being supplied through tube wells. However, the subsoil water in the area has very high Total Dissolved Solids (TDS) (more than 4000 PPM) and very high Chloride content (more than 2000 PPM), which makes it non-potable and harmful to humans. Public Health Engineering Department (PHED), under Govt. of Rajasthan, needed to supply drinking water throughout the region by drawing water from Chambal River located at a distance of 85.25 Kms

Key Components:

• The projects supplies water to 930 villages in Bharatpur District, 96 villages in Dholpur District, apart from urban towns of Bharatpur, Kumber, Deeg, Nagar & Kama.
• Design, engineering, construction, procurement and commissioning at Intake structure with steel approach bridge. Along with this, piers were built and truss was launched, as pioneering innovative works in the history of PHED.
• MS pipeline from Chambal river to Sagarpada head works. Earthen raw water reservoir at Sagarpada head works, Raw water pumping station and sub station
• Raw water main from Sagarpada to  Mallah head works
• Raw water reservoir at Mallah Head works, Raw water pumping station and sub- station.
• Water Treatment Plant at Mallah head works including Operation and Maintenance.
• Coffer Dam, Intake Structure, Pumping Stations, Retaining Wall, Switchyard, VT & HSC Pumps, Railway crossing with Jack Pushing

A drinking water supply project, conceived nearly 50 years ago for water-starved and fluoride-hit people of Krishnagiri and Dharmapuri districts in north-western belt in Tamilnadu, has become a reality on Wednesday 29th May when Hon’ble Chief Minister of Tamilnadu formally commissioned through video-conferencing.

The project, now called Hogenakkal Water Supply and Fluorosis Mitigation Project, was originally mooted when Mr. K. Kamaraj was Chief Minister in the 1960s. Over the years, it witnessed various changes and eventually, when the Dravida Munnetra Kazhagam was in power, the project took off.

But, the significance of the project is not just about the cost. It is going to serve people in a region, which is among less developed in many respects.

As per an estimate of the funding agency, the districts of Dharmapuri and Krishnagiri had, as of 2006, about 1.1 million people living below poverty line.

According to 12th Five Year Plan document of the State Planning Commission, human development indices of the Krishnagiri and Dharmapuri districts are 0.748 and 0.707 against the State’s overall figure of 0.765.

Known for chronic water shortage, the two districts receive less rainfall compared to many other parts of the State. Their average annual rainfall is 815 mm whereas the State’s annual rainfall is 977 mm. But, what affects them more is the presence of fluoride, harmful to the human body, in the groundwater. People suffer from dental and skeletal fluorosis, says a note prepared by the funding agency.

Taking into account all these aspects, the authorities have designed the project, which will benefit about 3.3 million spread over three municipalities, 17 town panchayats and 6,755 rural habitations in the two districts.

Using Cauvery as the source, the project can take care of the requirements of four million. On completion of the project, all rural habitations will have the prescribed norm of 40 litres per capita per day (LPCD) and the urban local bodies, 135 LPCD, adds the official.

Govt. of India together with TWAD Board mooted this major project to overcome water scarcity and presence of Flurosis in groundwater faced by two adjacent districts – Dharmapuri & Krishnagiri.

Water from Cauvery River is pumped 45 km to the 127.6 MLD Water Treatment Plant (WTP) and distributed to 3 municipalities, 17 town panchayats and 6755 villages in 18 panchayat unions. Subsequently, the WTP capacity would be raised to 155.82 MLD.

This EPC project, funded by Japan International Cooperation Agency (JICA), ensures safe drinking water to thousands of rural households in the region. It also provides water to 5 Unions by branch pipelines and Distribution lines of 130 Panchayats benefitting 1650 Habitations.
