I stumbled upon this interesting story, from Baluti Village in Nainital about a middle class farmer, Padmadutta Balutiya.
According to the elders in the area, in the late 1880s, the water in the Nal Damyanti Tal and its vicinity used to flow in the form of a rivulet across an area two kilometers long and down the hills to Bhabhar and Tarai area. However, the water could not be used, whereas there was tremendous need for irrigation in the neighbouring regions. During that period, Bhabhar area was in the process of being settled and water for irrigation and drinking was necessary for the settlements. Robertson, the British Commissioner at the time, had a dam constructed to retain the water in Bheemtal, so that it would not be wasted and could be used when the need arose, especially during the summer. But the dam broke down during the rainy season. Colonel Ramsay, who succeeded Robertson, was a generous and intelligent officer who, at the request of farmers, decided to do something to solve the problem of water shortage. He thought that if a check dam was made, the water from the natural source that was flowing away could be collected in the valley and could then be transported through canals. Accordingly, he made a proposal and sent it to London through the Viceroy of India. The proposal was accepted and Ramsay decided to construct a check dam.
As soon as Shri Padmadutt Balutiya came to know that Ramsey was going to build a dam, he went to the site and checked the design of the dam. He felt that the design was flawed and told Ramsey that it would not be able to withhold the water pressure. He suggested that instead of the straight wall, if the dam could be constructed with a convex shape it would resist the pressure of water, because the force of water would not concentrate at a particular point but would be distributed evenly over the entire length, thus minimizing the water pressure. Unfortunately, Ramsay did not heed his suggestions and had the dam constructed ‘his way’. The dam was washed off in the first rain. Ramsay tried three more times, but each time he met with the same results. He was, however; still not ready to listen to Padmadutt Balutiya. The next time, Ramsay wrote to London, explaining his case and asking for a specialized engineer. The engineer came and started the work with a new design. Again Padmadutt went to Ramsay and suggested that if this dam could not withhold the water pressure, he should be allowed to build the dam the next year according to his design. Ramsay agreed.
Padmadutt returned to his farm, but he was thinking all the time about the site of the dam 25 kilometers away. Finally he sent one of his farm labourers to the work site and asked him to report within the first week of rain. As he had predicted, the dam was washed away in the first rain and his man reported this to Padmadutt Balutiya before the official message came from Ramsay. Padmadutt immediately set out for Ramsay’s office and waited outside his room. When Ramsay came out, Padmadutt told him that the dam has been washed away. Till then, Ramsay had not received any official message from the work site. Impressed by the interest and initiative taken by Padmadutt Balutiya, he called a meeting and instructed every body to follow Padmadutt’s advice.
The 109-year old check dam in Bheemtal is truly a modern day wonder. The dam, designed by the late Padmadutt Balutiya in 1895 continues to stand strong and has not required any repairs since its construction. The check dam was designed based on the old traditional method i.e. “lehria” method which has been used to make bunds for rice fields since ancient times. The check dam is constructed in the form of a canal shaped like an arc. Water is allowed to enter this canal so that the force of the water inside the canal reduces the force exerted by the water from the outer side. This enables the check dam to withstand the heavy force exerted by the water. The pressure on the second wall of the dam is automatically reduced, as it is not in direct contact with the larger volume of water. Several outlets are made on the second wall of the dam so that water is discharged uniformly. These outlets are at different levels so that water can be discharged in such way that it exerts minimum pressure in the process.
Among many reasons given for this dam to stand the test of time for so many years, one is that the shape of the dam facing the flow of water is convex. Due to the presence of water on both sides of the dam, the pressure on the dam itself is lessened. In addition, instead of only one sluice gate, the check dam has four gates that dissipate the water pressure on the dam structure equally. The building material is unusual. Instead of cement, traditional materials such as lime, flour, powdered pulses, and straw have been used.
It's yet another wonder that too little of us know about him and his contributions.
