New NAIA Infra Corp. (NNIC) — the private operator of Ninoy Aquino International Airport (NAIA) — revealed on Wednesday that it has removed 139,158 metric tons of waste and silt from waterways surrounding the airport in an effort to address persistent flooding issues.

The cleanup effort, conducted with assistance from San Miguel Corporation’s (SMC) Better Rivers PH teams, has covered approximately 3 kilometers of river channels which include parts of the Parañaque River near Barangay Tambo, the Don Galo River and Villanueva Creek near Barangay La Huerta.

NNIC, which took over operations at NAIA in September 2024, has prioritized flood prevention. The company said it has cleared waterways, upgraded drainage systems, and improved the flow of rainfall around the airport. As a result, water drains more rapidly and accumulates less during heavy rains.

To further prevent flooding from backing up into the airport and surrounding areas, the NAIA operator has also addressed clogged storm drains and open canals along key roadways near the airport, including Domestic Road, NAIA Road, Airport Road and Andrews Avenue.

NNIC reported that 67 manholes have been cleaned and refurbished, with 17 receiving new covers. Additionally, seven new manholes have been constructed to improve drain access.

The company said these initiatives are coordinated with the Department of Transportation, Department of Public Works and Highways, Department of Environment and Natural Resources and the Parañaque City government, and are fully supported by NNIC and SMC.
