2. METRO MANILA FLOOD MANAGEMENT
The Philippines ranks third among countries most at risk for disasters,
including floods, storms, and earthquakes. In the past 30 years,
more than 360 disasters struck the Philippines, with a total death toll
of 33,000 people which affected 120 million people. Typhoons and floods are
the most devastating in terms of their economic and social impact.

3. Flood is "an abnormal progressive rise in
the water level of a stream that may result in
the overflowing by the water
of the normal confines of the stream
with the subsequent inundation of
areas which are not normally
submerged".

4. NATURAL CAUSES
Meteorological Events
- an intense and prolonged rainfall spells
- unusually high coastal and estuarine waters due to storm surges, seiches, etc
Seismic Activities
- tsunamis (seismic sea waves)
- sinking of land due to earthquakes reduces the elevation of land areas
- uplifting of lake and river beds from seismic causes sometime results in the
overflowing of these bodies of water
Astronomically-Influenced Phenomena
- high tides coinciding with the occurrence of heavy rainfall

5. ARTIFICIAL CAUSES
Blasting
- causes landslides in the slopes of hills and mountains which may result in the unintentional
damming of rivers and streams
Construction of temporary dams
- produces an impediment to the flow of a river or stream which then results in an overflow
Failure of hydraulic and other control structures
- accidents like the breaking of a dike result in the entry of an enormous quantity of water in
a protected area
Mismanagement of hydraulic structures
- may necessitate an untimely and sudden release of large amounts of excess water
Denudation of forest and watershed areas
- alter the ecological system in a river basin will have an impact on the hydrology of the
catchment

6. EFFECTS OF FLOODING
• millions even billions of pesos of damages to
roads and bridges, buildings and other econo
mic infrastructure, in the loss of agricultural
crops and livestocks, loss of productivity in
industry, commerce and trade
• incalculable loss of human lives
• forced human displacement
• emotional impact on those affected by floods
• lack of basic utilities and essential necessities
• contamination of the water supply
• epidemic of gastro-intestinal diseases and
respiratory ailments frequently breaks out

10. HOW DOES THE GOVERNMENT
CONTROL FLOODS?

11. $500 Million Metro Manila Flood Control
Management Project
1. ) The master plan proposed a set of measures to effectively manage major flood
events in the future which include the following:
• reduce flooding from river systems that run through the metropolis, by build
ing a dam in the upper Marikina River catchment area to reduce peak river
flows entering Metro Manila during typhoons and other extreme rainfall
events;
• eliminate long-term flooding in the flood plain of Laguna de Bay to protect
the population living along the shore against high water levels;
• improve urban drainage, including modernization of Metro Manila’s
pumping stations;
• improve flood forecasting and early warning systems and
community-based flood risk management; and
• improve institutional arrangements for better flood management.

Management Project
2.) 36 existing pumping stations will be modernized, 20 new
ones will be constructed, and supporting infrastructure along
critical waterways will be improved in the cities of Manila,
Pasay, Taguig, Makati, Malabon, Mandaluyong, San Juan,
Pasig, Valenzuela, Quezon City, and Caloocan.

13. $500 Million Metro Manila Flood Control
Management Project
3.) The project will improve management of solid waste within
villages in the vicinity of drainage systems served by the
pumping stations. It will also support government’s
resettlement of informal settlers that have encroached on the
waterways.

14. $500 Million Metro Manila Flood Control
Management Project
4.) The Department of Public Works and Highways (DPWH)
and the Metro Manila Development Authority (MMDA) will
implement the project in close coordination with local
governments and key shelter agencies. Slated to start in
2017, the project is scheduled to be completed in 2024.

15. $500 Million Metro Manila Flood Control
Management Project
5.) In 2015, the World Bank obtained a US$6-million grant
from the Australia-World Bank Philippines Development Trust
Fund and Policy and Human Resources Development Trust
Fund of Japan to finance studies and designs of other interve
ntions for the next phase of the master plan implementation.

18. PURPOSE AND CHALLENGES OF PUMPING
STATIONS
Stormwater pump stations help
protect areas by pumping away
large volumes of water, thereby
preventing the occurrence of
flooding.
PURPOSE
INSIDE THE PUMPING STATION BINONDO PUMPING STATION• Stormwater often contains solids
and large amounts of fibrous
material
• Large inflows occur within a short
period of time
• Operates for shorter periods over
the year but when needed
demands high operational
reliability
• Good trash racks are a must
CHALLENGES

19. MAINTENANCE OF PUMPING STATIONS
Major maintenance works at pumping stations and booster pump
stations include:
• daily and periodic inspection of electric and pumping
equipment to check for abnormalities
• record inspection data.
• periodic switching of equipment in operation as well as
systematic switching
• simple repairs at the time of construction or electric
equipment inspection
