Wastewater Challenges
The uncontrolled urbanization
of Metro Manila underlies poverty,
congestion, and environmental
pollution
In 1997, only 3% of Metro Manila had access
to sewerage system

Wastewater Challenges
35 percent reside in informal
"slum" settlements withimproper sanitation facilities
Wastewater continues to
discharge to rivers, morethan half of which come
from households

A balanced PPP framework and dynamic concession
agreement lead to investments and fulfillment of serviceobligations.
Manila Water’s multipronged, customized approach
explains the early successes in its wastewater
management program.
Water supply chain integration and full-cost recovery
ensure the sustainability of Manila Water’s wastewater
program over the life of the concession.
