Lima Marginal Areas Sanitary Improvement Project

The largest city in Peru, Metropolitan Lima has a population of eight million, and frequently experiences severe water shortages during the dry season that make securing water sources a high priority. The population in the surrounding areas is expected to grow due to a rapid influx of low-income residents and also continue expanding residential areas. Unfortunately, however, waterworks, sewer systems and other basic life-sustaining infrastructures remain underdeveloped, posing an environmental hazard to the residential area and a serious concern about the health and sanitation of local communities.

The objective of this project is to eliminate severe water shortages in Lima’s surrounding area by constructing new water treatment facilities (intake, potable water treatment plant, water transmission line) as well as improving general and secondary water and sewage networks. It is aimed at improving the living environment and sanitation for the local communities through proper sewage treatment.

The sanitary service is provided by Peru’s state water and sewerage utility known as SEDAPAL in the metropolitan area, but its existing purification plants already exceed its operation capacity, threatening adequate supply of water even if new water sources are secured in the future.
