Campos Novos Dam

The consortium led by the Brazilian construction giant Camargo Corrêa has said it will take a minimum of five months to complete repairs to the Campos Novos dam that failed a month ago.

The $554.4-million dam was slated to go fully on-line this month but on June 19, two of three gates on a diversion tunnel built to divert the flow of the Canoas River failed. Officials now estimate more than 1 billion cubic meters of water from the reservoir flowed downstream and was captured by the reservoir for another recently built dam.

The cause of the diversion tunnel failure and the cracks on the concrete face of the dam that alarmed observers have not been precisely identified, company officials said. But more information is expected to be released in early August when a report is presented to the Brazilian energy agency ANEEL.
