AMID fears that the aging Angat dam in Bulacan would collapse in case the “Big One” or the powerful earthquake jolts parts of Luzon, its operators will push through with its rehabilitation.
Filipino conglomerate San Miguel Corp. (SMC) has partnered with Korean firm Korea Water Resources Corp. (K-Water) for the operations of 218-megawatts (MW) Angat Hydroelectric Power Plant (HEPP).
Ramon S. Ang, SMC President and Chief Operating Officer said the rehabilitation of Angat dam is part of K-Water’s agreement with the government to ensure the efficiency of the power plant.
K-Water invited the company to be its main local partner with 60 percent stake in Angat hydro power plant.
“Rehabilitation of Angat dam is a go, that’s in the agreement,” Ang told reporters after the SMC’s annual stockholders’ meeting.
He said they are now waiting for the recommendation of the U.S. consortium company expert on dams Poyry, which conducted the Dam Safety Assessment (DSA) for the Angat hydro power plant.
Included in the services of Pöyry is the verification of the existence of an active fault as well as assessment of spillway capacity and dam rehabilitation plan.
The power plant, located about 60 kilometers northeast of Metro Manila, was constructed by the National Power Corporation (NPC) in the early 1960’s as a multi-purpose project for domestic water supply, irrigation, power and flood control.
Major structures of the Angat HEPP are the 131 meter high rock fill main dam with inclined earth core and the approximately 52 meters high rock fill dyke dam also with inclined earth core.
Ang said the rehabilitation works will address the problems on safety and structural integrity of Angat dam, which is located on the highest slope of the mountains in eastern Bulacan.
“No one can stop a massive earthquake, we will try to minimize the risk,” he added.
He also assured that dam operations will not be affected by the rehabilitation.
