Peru's Consorcio Norte, the consortium in charge of the Pachacutec-Ventanilla water project in port city Callao, will begin construction within 180 days, according to company spokesperson Jorge Salinas.
Work includes building seven large reservoirs and six wells to provide potable water to some 150,000 residents in Callao's Ventanilla and Pachacutec districts.
The 330mn-sol (US$120mn) project also includes installing some 600km of pipeline and 38,300 domestic connections, as well as building a wastewater treatment plant.
The project is being carried out under the government's Agua Para Todos (water for everyone) program and will take 660 days to complete.
The Ventanilla city government coordinated with the national government, Lima water utility Sedapal and community leaders to provide support for the project, including land transfers and the cleanup of construction areas.
