MANILA, Philippines — Manila Water Company’s Wawa–Calawis water supply system is significantly strengthening the reliable delivery of potable water to Metro Manila’s East Zone and parts of Rizal Province, reinforcing service amid rising demand and seasonal challenges.
The newly improved Wawa–Calawis system is part of broader efforts to diversify water sources and reduce overreliance on existing supply infrastructures. The project helps ensure that residents in busy urban areas, including Antipolo and neighboring Rizal towns, have more secure access to clean water.
Officials say boosting supply capacity through strategic infrastructure like the Wawa–Calawis system is vital—especially as the region anticipates periods of higher consumption during summer and other peak times. The system taps into additional sources beyond traditional reservoirs, providing a more resilient water network for millions of residents.
Manila Water’s service area, covering Metro Manila’s eastern cities and adjacent Rizal municipalities, has seen water demand grow consistently. Projects like Wawa–Calawis are part of long‑term plans to address current shortfalls and future needs through diversified water sources.
Water sector analysts note the importance of developing alternative supply projects alongside traditional sources like Angat reservoir and La Mesa treatment facilities to mitigate risks from drought or infrastructure strain.
Overall, the enhancements to the Wawa–Calawis system aim to strengthen water security for households and businesses across the East Zone and Rizal, reinforcing service quality in a densely populated region.
