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.The dam was constructed in late 1950s for irrigation and, along with three other dams nearby, Varasgaon, Temghar and Khadakwasla, it supplies drinking water to Pune.
Panshet Dam burst in its first year of storing water on 12 July 1961, when the dam wall burst, because of the total absence of reinforced cement concrete (RCC) strengthening in the conduit through the earthen dam. Plain unreinforced concrete blocks were used instead due to a shortage of steel.[1] causing massive flooding in Pune. An estimated 1,000 people died from the resulting flood.[2][3]
It is about 50 km (31 mi) from Pune and about 180 km (110 mi) from Mumbai.
The height of the dam above its lowest foundation is 63.56 m (208.5 ft) while the length is 1,039 m (3,409 ft). The volume content is 4.190 km3 (1.005 cu mi) and gross storage capacity is 303,000 m3 (10,700,000 cu ft).[4]
