INSTITUTIONALIZING THE METRO MANILA DRAINAGE

AND FOR OTHER PURPOSES
EXPLANATORY NOTE
Sections 16, Article II of the 1987 Constitution provides that the 
state shall protect and advance the right of the people to a balanced and 
healthful ecology in accord with the rhythm and harmony of nature.
A single typhoon can submerge cities, displace thousands, halt 
economies, and claim lives. A future where homes, businesses, 
hospitals, and schools remain dry, accessible, and safe—even during 
the heaviest of rains begins with one urgent necessity: Metro Manila 
Drainage Master Plan.
Metro Manila has no unified drainage framework. Each city 
builds independently, one project unaware of the other. National 
agencies implement drainage works that don’t match roadworks of 
local government units. This fragmented approach leads to chaos, 
flooding, and waste of public funds.
This representation believes that floods are not natural disasters, 
they are governance failures. It is the result of outdated, disconnected, 
and piecemeal drainage system. Metro Manila has grown but our 
drainage systems have not.


This bill seeks to institutionalize Metro Manila Drainage Master 
Plan as an enhanced 50-year strategic framework for Metro Manila’s 
long-term strategy for drainage infrastructure development. It will 
create Inter-Agency Drainage Management Council that will monitor, 
review, and streamline existing policies to avoid duplication of 
functions, ensure effective use of resources, and harmonize and 
complement all governmental efforts. The measure also aims to 
mandate local government units within Metro Manila to align their 
drainage development plans with the Metro Manila Drainage Master 
Plan.
In view of the foregoing, the passage 
sought.
easure is earnestly
ULFO
