Project Noah proposes 150 detention basins to combat Metro Manila flooding
A major flood mitigation initiative calls for construction of over 150 detention basins across Metro Manila to reduce inundation during heavy rainfall events. The infrastructure project aims to temporarily capture excess rainwater before it reaches vulnerable low-lying communities.

MANILA—Project Noah has unveiled an ambitious plan to construct more than 150 detention basins throughout Metro Manila as part of a comprehensive strategy to mitigate seasonal flooding that regularly affects the sprawling metropolitan area.
Executive director Mahar Lagmay outlined the proposal during a press briefing Thursday, emphasizing that the detention basins would serve as temporary storage facilities for excess rainwater during periods of intense precipitation. By capturing runoff that would otherwise inundate low-lying neighborhoods, the infrastructure could significantly reduce flood damage and protect residents in vulnerable communities.
The detention basins represent a key component of Project Noah's multi-faceted approach to flood management in Metro Manila, a region that faces recurring inundation challenges due to its geography, drainage constraints, and exposure to tropical weather systems. Officials believe the distributed network of storage facilities would enhance the capital's resilience to extreme rainfall events.
The proposal comes as authorities continue efforts to upgrade Metro Manila's aging drainage systems and implement nature-based solutions alongside traditional infrastructure improvements. Further details regarding project timeline, funding mechanisms, and site identification are expected to be disclosed in subsequent announcements.
