The Campos Novos Dam (also known as Barragem de Campos Novos locally) is a hydroelectric dam in the Santa Catarina state in southern Brazil. In 2006, at 200 metres (660 ft) dam height, it was regarded[who?] as the third highest[citation needed] dam of this type (concrete-faced rock fill dam or CFRD) in the world, but, in June 2006, the water which it held back ran out following a break in the dam wall.
Built at a cost of $671 million
Ownership and construction
Campos Novos' 35 years build and operate concession was awarded in 1998. It is owned by Campos Novos Energia S.A. ("Enercan"), a consortium made up of Brazilian power company
The dam builder was a consortium led by Brazilian construction company
Cracks
A major break caused the water to begin to run out, after a tunnel collapsed on 20 June 2006. The exact reasons for the cracking were unknown in July 2006, however it has been revealed that patches were begun on another tunnel in October 2005 before the recent tunnel failure.[1][2]
Since the dam failure, a full inquiry for the reasons behind the cracks has been done, and a time-line of the dam's progression towards failure has been completed.
Camargo Corrêa re-plugged the tunnels in November 2006 and the reservoir was refilled by 1 March 2007. The last of the three generators went on-line on 30 April 2007.
