“Now we’re talking of sustainability, we’re talking of growth, we’re talking of Clark as the gateway to the Luzon Economic Corridor,” CDC President and CEO Agnes Devanadera said.

Once completed, the new plant will increase treatment capacity from 27 MLD to 37 MLD.

According to CDC Construction Management Division Manager Rogelio Magat, technical studies showed the Freeport needs additional capacity to keep pace with rising wastewater demand.

“We’re not just addressing the current demand for sewer services in the Clark Freeport Zone, but we’re also making sure that future developments in the Clark Freeport Zone will have appropriate sanitation services,” said Melvin Tan, chief operating officer of Manila Water Non-East Zone.
