Building historical past

Earlier than the devastating floods of 1936, Sir M. Visveswararya proposed an in depth investigation for storage reservoirs within the Mahanadi basin to deal with the issue of floods within the Mahanadi delta.

Hirakud Dam

The Central Waterways, Irrigation and Navigation Fee took up the work. On 15 March 1946, Sir Hawthorne Lewis, the Governor of Odisha, laid the muse stone of the Hirakud Dam. A venture report was submitted to the federal government in June 1947. Pandit Jawaharlal Nehru laid the primary batch of concrete on 12 April 1948.

In 1952, Mazumdar Committee was appointed by the federal government to supervise the soundness and technical feasibility of the venture.

The committee has envisaged prices of ₹92.80 crore for the venture and that the development of the primary dam can be full by June 1955. It additionally stated that by 1954–55 a complete of 1,347,000 acres (545,000 ha) can be irrigated and that 48 GW of electrical energy can be generated.

Nonetheless, the dam was accomplished in 1953 and was formally inaugurated by Prime Minister Jawaharlal Nehru on 13 January 1957. The full value of the venture was ₹1,000.2 million (equal to ₹75 billion or US$1.1 billion in 2018) in 1957. Energy era together with agricultural irrigation began in 1956, reaching full potential in 1966.

Within the higher drainage basin of the Mahanadi River, centered on the Chhattisgarh Plain, periodic droughts distinction with the scenario within the decrease delta area the place floods might harm crops.

The dam was constructed to assist alleviate these issues by making a reservoir and controlling river circulate by the drainage system. The dam regulates the circulate of the Mahanadi River and produces hydroelectricity by a number of hydroelectric vegetation.

The dam helps management floods within the Mahanadi delta and irrigates 75,000 km2 (19×106 acres) of land. Hydroelectricity can also be generated.

The Hirakud Dam regulates 83,400 km2 (20.6×106 acres) of Mahanadi’s drainage. The reservoir has a storage capability of 5.818 km3 (1.396 cu mi) with gross of 8.136 km3 (1.952 cu mi).

It drains an space of 133,090 km2 (32.89×106 acres), greater than twice the world of Sri Lanka.

The quantity of earth, concrete and masonry supplies used to construct the dam is ample to make a highway 8 m (26 ft) vast and pave it from Kanyakumari to Kashmir and from Amritsar to Dibrugarh in Assam. With profitable irrigation supplied by the dam, Sambalpur is known as the rice bowl of Odisha.
