At the core of this initiative is the Hinulugang Taktak Sewage Treatment Plant (HT STP), which has entered the liquid process commissioning phase—a key milestone in the ongoing rehabilitation of the historic Hinulugang Taktak Falls.
Mobilized in 2021, the sewerage system plays a vital role in protecting one of Antipolo’s most iconic natural landmarks.
By collecting and treating used water from nearby communities before it is discharged, the project ensures cleaner waterways and a healthier environment for both residents and visitors.
The P2.2-billion infrastructure highlights Manila Water’s dedication to long-term environmental stewardship and community well-being, aligning with national goals for sustainable water resource management.
Protecting a landmark
The Hinulugang Taktak Sewerage System integrates several key infrastructure components that are now close to full operation.
These include the 16-million-liter-per-day HT STP, which uses advanced Moving Bed Biofilm Reactor (MBBR) technology, a terminal pumping station, a lift station and force main, and a gravity-based sewer network system.
Together, these facilities are designed to serve more than 148,000 residents in Antipolo City—particularly those in Barangays Dela Paz, San Isidro, Sta. Cruz, and San Jose.
Beyond its technical scope, the project reflects Manila Water’s broader goal of balancing urban development with environmental protection, ensuring that growth in Rizal Province remains sustainable.
Sustainability in Action
To date, the HT STP stands as the first and largest sewage treatment facility in Rizal Province. Its completion marks a milestone not just for Manila Water, but for the communities it serves—supporting public health, safeguarding natural resources, and preserving an important cultural landmark.
“The Hinulugang Taktak Sewerage System project is a symbol of our commitment to protecting our environment and uplifting communities,” Jeric Sevilla, Manila Water communication affairs group director, said in a press release.
“By investing in sustainable infrastructure, we are helping ensure that future generations can continue to enjoy the beauty and heritage of Hinulugang Taktak.”
This initiative stands as a testament to Manila Water’s mission to deliver sustainable wastewater services that protect both people and the planet. —Ed: Corrie S. Narisma
