Ramanathapuram Mega Drinking Water Supply Project

Section: Achivements pages are not under access control

Success Story

Ramanathapuram District, situated in the South-East corner of Tamil Nadu State, is highly drought prone and most backward in development. It is surrounded by Pudukkottai District on North, Sivaganga and Virudhunagar Districts on the Northwest and West, Tirunelveli, Thoothukudi Districts and Gulf of Mannar on the South and the Palk Strait on the East. The district in its present form came into existence from 15th March 1985 by trifurcating the composite Ramanathapuram District. The district has an area of 423344 hec. The unique feature of the district is the longest coastal line measuring about 265 kilometers accounting for nearly 1/4th of the total length of the coastal line of the State.

Ramanathapuram District comprises of 7 taluks, 11 blocks and 444 village panchayats. As regards the hierarchy of administrative arrangements, there are 4 Municipalities, 7 Town Panchayats and 2332 rural habitations in 11 panchayat unions in this district. Average rainfall of the District is 827mm. But the quantum of rainfall is not only uneven, but also erratic. The soil of Ramanathapuram can be assorted into clay, coastal alluvium, alluvium, sandy clay and black cotton soil. District of Ramanathapuram is an index of National integration & major attraction for pilgrims & tourists from all parts of the globe as well.


The Holy abode of the Hindu God, Shri Ram (addressed so with all respect & humility) is a virtual paradise for the devout. No Hindu’s journey is complete without a pilgrimage to both Varanasi and Rameswaram for the culmination of his quest for salvation and is hallowed by the epic ‘Ramayana’. Folklore mentions about God Ram’s presence in this land, after his 14-year exile.

Sea World Aquarium

Just opposite the Rameswaram Bus stand one can catch a quick glimpse of an assortment of under water creatures in their near natural habitat in the ‘Sea World Aquarium’ – the only one of its kind in the state and probably in the country too filled with such varied marine life forms including exotic species like octopus, sea lizard, cow fish, lobsters, star fish etc.


The deity in the temple is carved in Emerald. Annual Arudhra' festival in December attracts a large number of devotees.


The tomb of Sultan Ibrahim Syed Aulia, who came from Arabia via Cannanore, is about 800 years old. Pilgrims from far off countries like Srilanka, Malaysia and Singapore are visiting this tomb. Santhanakoodu Festival is celebrated in February-March attracts thousands of pilgrims.


Its one of the most revered pilgrim centers for Christians the world over.

Annai Indira Gandhi Bridge

The 2.2 km. Length Bridge connecting the Rameswaram Island and the mainland is the longest bridge in India constructed over a bay. It is also called as Pamban Bridge. Similarly the railway bridge connecting the island is noted for its unique opening to pass the ships through the sea.

His Excellency the former President of India Dr.A.P.J.Abdulkalam belongs to Ramanathapuram District.

Tamil Nadu Water Supply and Drainage Board

The Government of Tamil Nadu constituted the Tamil Nadu Water Supply and Drainage Board (TWAD) on 14.4.1971 by an Act called "Tamil Nadu Water Supply and Drainage Board Act”. The Board was formed with a view to be set up as an autonomous body on a statutory footing so as to conduce speedier planning, investigation and execution of schemes and also enable it to raise substantial resources from financing institutions and in the open market to provide drinking water and drainage facilities to urban and rural areas in the State of Tamilnadu except Chennai Metropolitan areas. A nodal agency for implementation for mega water supply projects with bilateral assistance – World Bank, UNICEF & DANIDA, etc.,

Need for Project

Ramanathapuram District in Tamilnadu is severely affected by scarcity of potable water due to salinity, brackishness and also poor sources. As far as drinking water supply scenario is concerned it is a well-known fact that Ramanathapuram district is suffering from water shortage for many years and the district is not able to supply even the minimum 40 lpcd of potable water to the people for the last 100 years. The rainfall in this district is 827 mm which is much below the State average of 925mm.

Because of non-availability of potable water, the District is lagging behind in Economic and Industrial development compared to other Districts of Tamilnadu. Various water supply schemes like Individual Power Pump, (1161, IPPs); Mini power Pump, (485) stand- alone schemes (11), Combined Water Supply scheme (36) & Desalination Plants (20) have been implemented but sources could not sustain schemes due to Quality & Quantity problems in Ramnathapuram. Even improvement of Oornies could not provide potable & quality water to 15.75 lakhs of present population.

Foundation Stone Laid

Considering all the above factors, the Hon’ble Chief Minister of Tamilnadu laid the foundation stone on 30.01.2007 for a mega Combined Water Supply Scheme with river Cauvery as source in Trichy District at an estimated cost of Rs. 616.00 crore to solve the drinking water problem in Ramanathapuram district.

Project Profile

This scheme has been formulated to cover 5 Municipalities, 11 Town Panchayats and 3163 rural habitations in 18 Panchayat unions of Ramnathapuram, Sivaganga and Pudukottai Districts benefiting present population of 15,75,682. National Tender by following Tamilnadu Tender Transparency Act, 1998 was adopted to finalize 7 Packages for execution of Project.

Population Benefited

This scheme was funded with assistance from Government of India Urban Infrastructure Development Schemes for Small and Medium Towns (UIDSSMT) of Rs.282 crores and Rs.273 crores from National Agricultural Bank for Rural Development (NABARD) to implement this mega project for Urban and Rural local bodies. The tender process was finalized by September 2007.
