OAS to Complete Huascacocha Dam Construction in Peru

Brazil-based construction firm OAS is expecting to complete the construction of a $94.7m Huascacocha dam in Peru next month, the company has announced.

Water utility Sedapal said that 98% of work has now been completed.

OAS was contracted to build, operate and maintain a dam and water transfer system from the Huascacocha lake in the Pasco region to the existing Marca III system, and then to the Rímac river in the capital Lima.

Work under the project includes building a 15m dam wall, which will store 686Mm³ of water and 22.5km of transfer pipelines.

According to an agreement made with Sedapal, Peru’s power company Edegel is co-financing the Huascacocha dam and will use water from the dam to supply four hydroelectric plants.
