Panshet Dam

Panshet Dam, also called Tanajisagar Dam, is a dam on the Ambi river, a tributary of the Mutha River, about 50 km (31 mi) southwest of the city of Pune in western India.

History

The Panshet Dam burst on 12 July 1961, during its first year of storing water. The failure occurred when the dam wall gave way due to the complete lack of reinforced cement concrete (RCC) reinforcement in the conduit passing through the earthen structure. Instead of using RCC, plain unreinforced concrete blocks were installed, owing to a shortage of steel at the time.^[1] This critical design compromise led to a catastrophic failure, resulting in massive flooding in Pune and an estimated death toll of around 1,000 people.^[2][3]

It is about 50 km (31 mi) from Pune and about 180 km (110 mi) from Mumbai.
