The Peruvian government signed an agreement with Canadian Commercial Corporation, a governmental entity, to build three sewage treatment plants in the capital for a cost of 350 million dollars. A mere five percent of wastewater in Lima, home to eight million people, is treated before being dumped into the sea. The result is highly polluted ecosystems at the dump points.

The initiative is to begin with the construction of the San Bartolo sewage plant, which alone will boost the capital's wastewater treatment coverage to 23 percent.
