Clark Freeport is boosting its wastewater treatment capacity by 10 million liters per day (MLD) as a Manila Water unit builds a new facility to meet growing demand in the mixed-use zone.
The expansion at the Clark Centralized Wastewater Treatment Facility will feature a sequencing batch reactor with biological nutrient removal technology to improve treatment efficiency.
On Wednesday, Clark Development Corp. (CDC) broke ground on the project, as it expands the Freeport’s utility infrastructure amid continued investment growth.
‘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.
Clark Water, a Manila Water unit, provides water and wastewater services in the Clark Freeport.
As of 2025, it has served nearly 2,000 investors through a 254-kilometer sewer network that provides full wastewater service coverage and connects to the centralized treatment facility.
Meanwhile, Manila Water said it has invested P6.6 billion since acquiring Clark Water in 2011 to upgrade the Freeport’s water supply and wastewater infrastructure.
The latest project forms part of a broader investment program announced last year.
In November, Clark Water committed P17.3 billion through 2040 to modernize utility infrastructure and expand water and wastewater systems across the Clark Freeport.
