MWIS cuts water losses at PEZA-Cavite by 1.7 million liters daily

MANILA, Philippines — Manila Water Infratech Solutions (MWIS) said it recovered about 1.7 million liters of water per day after completing a four-month non-revenue water optimization program for the Philippine Economic Zone Authority-Cavite (PEZA-Cavite).

MWIS, an operating unit of Manila Water’s Non-East Zone, said the program sought to improve water system efficiency, operational reliability and resource sustainability across PEZA-Cavite’s facilities.

The program involved network diagnostics, hydraulic engineering and field investigations to assess PEZA-Cavite’s water production, transmission and distribution facilities.

MWIS also established two district metered areas, or DMAs, to provide greater visibility into water movement across the network and allow more precise monitoring of consumption and system losses.

The DMAs enabled MWIS to isolate service zones, improve water balance analysis and identify areas requiring operational intervention.

The company also conducted step-testing and acoustic leak detection activities to identify hidden leaks and other inefficiencies in the distribution system.

MWIS replaced critical gate valves to improve network control, zone isolation and operational flexibility during maintenance and repairs.

These measures allowed the program to recover about 1.7 million liters of water per day, reducing losses and improving system efficiency during the four-month implementation period.

MWIS also developed and calibrated a hydraulic model of the network to simulate water flow and pressure under different operating conditions.

According to the company, the model was used to optimize water distribution, identify operational bottlenecks and evaluate possible infrastructure improvements.

The hydraulic simulations also guided operational adjustments aimed at improving network efficiency and reducing reliance on energy-intensive facilities.

“At MWIS, we believe that effective water management begins with a clear understanding of system performance. Through a combination of data-driven analysis, hydraulic modeling, and targeted field interventions, we were able to help PEZA-Cavite recover significant water losses and improve overall network efficiency,” MWIS General Manager Adrian Bryan Magallanes said.

“This project demonstrates how innovative NRW management strategies can strengthen operational reliability while supporting long-term resource sustainability,” he added.

Magallanes said MWIS was also committed to helping PEZA-Cavite improve the efficiency and resilience of its water distribution system.

“We are proud to partner with PEZA-Cavite in enhancing the efficiency and resilience of its water distribution system. We remain committed to delivering solutions that drive efficiency, sustainability, and operational excellence for our partners,” he said.
