Panshet Dam, also called Tanajisagar Dam, is a dam on the Ambi river, a tributary of the Mutha River, about {{convert|50|km|mi|abbr=on}} 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.
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.{{cite web|url=http://www.dnaindia.com/india/report_what-went-wrong-at-panshet-dam_1565039|title=What went wrong at Panshet dam?|work=dna|access-date=10 April 2015}} 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.{{cite web|url=http://www.sakaaltimes.com/NewsDetails.aspx?NewsId=5671671830883101811&SectionId=5171561142064258099&SectionName=Pune&NewsDate=20100711&NewsTitle=July%2012,%201961...|title=July 12, 1961... – Sakal Times|work=sakaaltimes.com|access-date=10 April 2015|archive-date=1 April 2016|archive-url=https://web.archive.org/web/20160401193748/http://www.sakaaltimes.com/NewsDetails.aspx?NewsId=5671671830883101811&SectionId=5171561142064258099&SectionName=Pune&NewsDate=20100711&NewsTitle=July%2012,%201961...|url-status=usurped}}{{Cite web|url=https://www.asianage.com/india/all-india/030719/flashback-tiware-dam-breach-invokes-memories-of-panshet-that-killed-1000.html|title=Flashback: Tiware dam breach invokes memories of Panshet that killed 1,000|date=2019-07-03|website=The Asian Age|access-date=2019-07-08}}
