Bringing Clean Water to Ellandoppu, Tamil Nadu, India

Ellandoppu is a poor village in the northeast of Tamil Nadu, which is the southernmost state of India with a growing population of more than 72 million people. Although many of the neighboring villages are predominantly Dalit, the name somewhat loosely applied to groups formerly known as “untouchables”, people in this particular village belong to what is known as an MBC caste. In the hierarchy of castes these are considered slightly “higher” than Dalits, even if the acronym MBC stands for a “most backward caste”, a title that strikes an odd note to anyone unaccustomed to the complexities of the caste system.  Ellandoppu lies some miles outside Mamallapuram which, in earlier times was a lively and important port on the ancient trading routes between East and West. Chinese and Roman coins dating back to the 4th century CE have been found there. Today Mamallapuram is a tourist center and its amazing rock carvings, from the time of the 7th and 8th century Pallava dynasty, are described by many as one of the wonders of ancient India.

 

Just beyond Mamallapuram’s golden beach, with its colorfully decorated and high-powered fishing boats, people come from far and wide to see the famous Shore Temple. It is a sanctuary adorned with thousands of sculptures in honor of Shiva, one of the three gods, along with Vishnu and Brahma, in what is often described as the Hindu Triad or Great Trinity. Most impressive of all, for me at least, is an area dedicated to the monolithic and beautifully sculpted rathas, or five “chariot” shrines, each one of them carved on the spot from a single piece of granite. A huge and exquisitely carved elephant, he too sculpted from one massive block of granite, stands guard at the side of the ratha shrines.

 

Nearby is a gigantic open-air relief, carved directly out of the rock with a panoply of elephants and other animals, people and gods assembled to celebrate the Descent of the Ganges, the river most sacred to Hindus. This sculpture, which stretches along a rock face for over a hundred yards, is also called Arjuna’s Penance. It is so-named after the ascetic figure of Arjuna, standing on one leg with his hands joined above his head, supplicating the gods for a favor. One of the memorable features in this rock sculpture is the mischievous figure, lower down on the right-hand side of the rock, of a cat standing in exactly the same posture as the ascetic Arjuna before an audience of excited kittens – a delightful touch of humor within a religiously inspired and magnificent work of art. 

 

Ellandoppu, by contrast, has no such glories. There is a brightly decorated shrine venerating the Elephant-Headed Ganesh, one of the best-known and most popular in the Hindu pantheon of deities, but that’s about it. Very close to the Ganesh shrine there is the Ellandoppu Village Community Center, constructed by Save Int’l. This serves nightly and on the weekends as a tuition school to help the Tamil students learn English, a necessary passport to their future, and to offer free coaching for the all-important national 10th grade exams. WaterBridge Outreach has donated books for use in this tuition school. Gail Tsukiyama and Mary Roach used these books and read with the children in the course of their visit to Ellandoppu.  You can find photos of them with the children, and with Gnanasekkaran, the excellent teacher there, via the Projects Now tab on our Home Page. 

 

When I was there in 2012, Curt Degler, president of Save Int’l, and I met with the village headman and his associates to talk about their water problem. They had no clean water for drinking, washing pots, and general sanitation. The already toxic state of the water had deteriorated further after the infiltration of salt water from the sea following the devastating Indonesian earthquake and tsunami of October 25, 2010. That powerful tsunami caused damage in Tamil Nadu, right across the other side of the Indian Ocean from Sumatra.

 

Discussions went back and forth between the villagers and ourselves in the following months. At WaterBridge Outreach we judged that if we constructed a reverse osmosis (RO) system, which would enable the water to be pushed forcefully through membranes designed to remove the salt and most of the toxins, Save Int’l and ourselves would be able to bring clean drinking water and better sanitation to the villagers, as well as to the children who come from the surrounding area to use the tuition school. 

 

Before moving forward we needed to be reasonably certain that the villagers would play their part in preparing the way for the RO system and, very importantly, in the necessary maintenance afterwards. Curt already knew the headman and felt this was a village we could work with, being fairly confident of how the funds would be utilized in a country where corruption is a phenomenon with which all Indians are only too familiar. As a pledge of the villagers’ seriousness we asked that they construct a small building that would be able to house the RO system. The two first photos of this RO system at Ellandoppu on our Home Page show firstly, a moment in the early discussions, when there was nothing except a poorly functioning water tank, and secondly, the housing actually in the process of being built.

The remaining two photos show the finished construction from the outside, as well as Curt and village women collecting water.  

 

This is the first of the RO systems we have financed in this area and it is very encouraging to know that it is working well. The water has gone through comprehensive testing at a government laboratory and is so pure that the villagers are now selling water to neighbors at the very accessible price of two rupees for 15 liters of water. Curt himself is now using this as his drinking water. As time goes on the most important issue will be maintenance - so often a problem with the water systems installed by outside organizations in areas of the developing world. In Tamil Nadu we are, as far as possible and together with Save Int’l, building maintenance into our water programs to try to ensure lasting long term impacts. 

 

At WaterBridge Outreach, what is distinctive is that – project by grassroots project and working alongside others with local knowledge - we see our work with books and literacy as going hand-in-hand with what we aim to do in terms of clean water and sanitation. The latter is an essential part of the infrastructure that allows education. That in turn will enable the villagers and young people themselves to serve and develop their own communities. The experience of the RO system at Ellandoppu is an encouragement for us to do more of the same, step by careful step.
