GUDC chief executive officer Toshikazu Nomura said
the Japanese project will be a 25-year build-operate-transfer scheme, at no cost to the Philippines, with the Metropolitan Waterworks and Sewerage System (MWSS) paying through the agreed water rates.
The Chinese project, meanwhile, entails a loan with an interest rate of 2 percent, said to be eight times higher than most Japanese loans.
The Chinese project will also cost double at $800 million, compared to the Japanese project cost of $400 million for almost the same capacity (600 million liters per day for China and 550 MLD for Japan). It would take the Japanese only 36 months to finish, well during Mr. Duterte’s term. The Chinese? Fifty-four months.
Nomura also touted the GUDC project as highly sustainable and will not inundate communities, since only a weir will be built—a low dam of 7 meters high and 16 kilometers long across the river.
China, on the other hand, is set to build a 62-meter-high dam and a 27.7 km conveyance water tunnel to Tanay, Rizal, that will flood Barangay Daraitan and other areas.
“We cannot understand why MWSS wants such high dam, we only need 600 MLD. It does not make common sense,” Nomura pointed out. And he added a damning detail: The GUDC had secured a memorandum of understanding from the MWSS as early as 2009, and was asked to resubmit its offer in 2017. However, Nomura said, “somebody in your government gave pressure” on the MWSS not to entertain GUDC anymore.
