Metro Manila Integrated Flood Risk Management Master Plan
ISSUES




Annual Typhoons average of 20 per year
Lack of integrated plan and strategic program to address perennial flooding and
other water related disasters like landslides, lack of potable water, siltation, etc.
Massive urbanization and lack of effective land use plans in Greater Metro
Manila has aggravated flooding
Water ways have been encroached and constricted by illegal structures causing
massive flooding of the metropolis
2
Effects of Water Related Disasters
 $160 Million damaged annually to the economy
 640 lives lost annually
 3.4 Million people affected annually
 71,000 houses totally damaged annually

Policy Directions and Programs
Integrated Water Resources Management Approach in Coordination with other
Departments/Agencies, LGUs and Communities
 Master Plan for Flood Management and clearing of water
ways of Metro Manila together with MMDA, LGUs and DILG
 Water convergence program initiated with DPWH, DA, DAR and
DENR.
 Since 2011, DPWH funded and is implementing various flood
control projects and eleven (11) small water impounding projects
(SWIPs) in the total amount of P 725.4 Million.
 Prioritization of SWIP sites based on:
a) list of flood-prone areas
b) list of 140 critical watersheds prioritized by DENR supporting
NIA-RIS and
 DPWH flood control projects in priority river basins
