Grana y Montero SA is seeking Peru’s backing for a $150 million sewage-treatment project to reduce pollution that is tainting waters in the world’s highest navigable lake, the state news agency Andina reported.
The biggest construction company in Peru will request a 30-year contract to build and operate at least 10 sewage-treatment plants in provinces that dump wastewater into Lake Titicaca, the state news agency said, citing Puno Governor Mauricio Rodriguez.
Lake Titicaca, at 3,100 meters (12,500 feet) above sea level, is a popular tourist attraction that straddles the border between Peru and Bolivia. Population growth and the expansion of unregulated mining activity have increasingly contaminated the 8,300-square-kilometer (3,200-square-mile) lake.
Grana y Montero plans 6 months of studies before starting work on the plants after it obtains government approval, Rodriguez said, according to Andina.
