THE Metropolitan Manila Development Authority (MMDA) has proposed the construction of rainwater impounding facilities inside Camp Aguinaldo to ease recurring flooding on EDSA, with the proposed design released on Wednesday, Aug. 27.
The plan requires detention ponds that will temporarily store excess rainwater during downpours and gradually release it into the EDSA drainage system, leading to the Makiling Creek.
As proposed, the project will be implemented in three phases, covering 182 hectares and involving a golf course near Gate 2, another near Gates 3 and 4, and an open space near Gate 6.

For the first phase near Gate 2, the detention pond has a 361-meter perimeter, a 4,650-square-meter area, an 8-meter depth, and a 37,200-cubic-meter capacity, designed for a 25-year return period (15.6 mm per hour over 24 hours), exceeding the needed 36,945 cubic meters.

MMDA’s schematic shows that under normal weather, the water bypasses the pond and flows through the lagoon to EDSA.
During heavy rain, floodgates divert water flow into the pond; after rain, pumps discharge stored water slowly into EDSA toward the Makiling Creek.
The scope of works covers the impounding area, operations and powerhouse, drainage and electromechanical works, and landscaping and golf course restoration, with a treatment facility under consideration.
Officials said operations and maintenance arrangements, and a memorandum of agreement, are still under discussion.
