THE Metropolitan Manila Development Authority (MMDA) has officially commenced improvement and maintenance works at the Padre Faura Pumping Station in Manila.
The infrastructure upgrade is designed to significantly reduce flooding along the vital Taft Avenue corridor, aligning with President Ferdinand R. Marcos Jr.’s directive to fast-track critical flood-mitigation initiatives.
Under Phase 1 of the development, the station’s detention pond capacity will be expanded by up to 1,500 cubic meters.
This enhancement involves both enlarging the existing storage structure and constructing an additional facility dedicated to holding excess floodwater.
To improve water outflow, the station’s overall discharge capacity will be boosted to three cubic meters per second.
This will be achieved through the installation of a new submersible axial pump capable of clearing one cubic meter of water per second.
According to the MMDA, these interventions are engineered to tackle the immense volume of stormwater generated during heavy downpours reaching 100 millimeters per hour—an estimated 1,265,011.20 cubic meters, or the equivalent of 506 Olympic-sized swimming pools.
Such downpours typically trigger ankle-deep flooding (approximately 0.4 meters) across four key catchment zones: Faura, Remedios, Abad, and P. Ocampo/V. Cruz.
Upon completion, the mitigation measures are projected to cut floodwater volume by 185,860 cubic meters—equivalent to 74 Olympic-sized swimming pools.
Consequently, average flood depths in the target areas are expected to drop from 0.40 meters to 0.34 meters.
Furthermore, complementary rainwater impounding facilities established in adjacent locations, such as the Rizal Memorial Sports Complex, are anticipated to work in tandem with the station upgrades, driving down floodwater volume by 59% across the four affected catchments.
