Built to protect: SM Prime’s flood mitigation strategy

· Leave a comment ·

SM Prime Holdings (SM Prime), a pioneer in sustainability initiatives in the Philippines, has long been committed to environmental stewardship and building resilient structures. From its early adoption of water recycling and innovative energy management programs to operationalizing renewable energy and waste management, SM Prime has consistently prioritized sustainability. This commitment was further underscored by the company’s active participation in the recent Asia Pacific Ministerial Conference on Disaster Risk Reduction, hosted by the Department of Environment and Natural Resources and the Office of Civil Defense. At the conference, Hans Sy, Chairman of the Executive Committee, emphasized the critical role of resilience in urban populations and how innovation and multi-sectoral collaboration are essential for the country’s sustainable development.

The Philippines is highly vulnerable to natural hazards, especially tropical cyclones and typhoons, making disaster risk management (DRM) and resilient infrastructure crucial. SM Prime employs a hydrological survey approach in building locations to determine flood susceptibility. 

SM City Marikina prioritizes safety with flood mitigation measures, ensuring a secure and comfortable environment for the community.

SM City Marikina, elevated on 246 concrete stilts, allows floodwaters to flow beneath, keeping occupants safe during severe weather events.

A strong example of such resilience lies in SM City Marikina, whose unique structure was lauded by the United Nations Office for Disaster Risk Reduction. Built beside the Marikina River, an area prone to flooding during severe weather events, SM City Marikina stands on 246 concrete stilts. This innovative design allows floodwaters to flow beneath the structure, leaving the mall and its occupants safe and dry. During Typhoon Ondoy (Ketsana) in 2009, which devastated surrounding areas, SM City Marikina remained intact, serving as a refuge for those affected by the disaster. Similar to the stilts methodology, SM City Cabanatuan’s lower ground parking level serves as a temporary catchment basin.

SM City Cabanatuan demonstrates SM Prime’s dedication to flood mitigation through its robust design. 

SM City Cabanatuan’s lower ground parking level doubles as a temporary flood catchment basin, a crucial element of our flood mitigation strategy. 

Beyond these two malls, this promise of flood resilience is present in other properties. A key innovation employed by SM Prime is the implementation of rainwater catchment basins in its malls. These massive underground tanks, similar in size to swimming pools, collect and store rainwater from the street level, mitigating flooding in surrounding communities. Twenty-nine SM Supermalls across the country are equipped with these basins, boasting a combined capacity of 85,400 cubic meters – enough to fill over 34 Olympic-sized swimming pools!

Built to protect, SM City Masinag incorporates a rainwater catchment basin to minimize the impact of heavy rainfall.

SM City Masinag’s rainwater catchment basin collected 8,652.60 cubic meters of rainwater during Super Typhoon Carina.

Designed with the community in mind, SM City Masinag incorporates flood mitigation measures for safety.

These catchment basins have proven invaluable during recent typhoons. For instance, SM City Masinag’s rainwater catchment basin played a crucial role during Super Typhoon Carina (Gaemi) last July 2024, effectively managing the increased water volume. It collected 8,652.60 cubic meters of rainwater, equivalent to 264 gallons of water. As the first SM mall equipped with a rainwater catchment basin, SM City Masinag was strategically built in a historically flood-prone area, serving as a catch basin for water flowing down from upper Antipolo. In the second half of 2024, SM malls prevented an estimated total of 46,405 cubic meters of rainwater–the volume of 18 Olympic-sized swimming pools–from flooding the surrounding areas.

Mr. Gareth Aboy, a resident and former officer of Vermont Phase 1 Association near SM City Masinag, expressed his gratitude: “The residents of Vermont Park Executive Village of Antipolo would like to extend our thanks and appreciation to SM City Masinag for always being there in our times of need. Thank you for keeping your doors open for our immediate daily needs, your elevated parking spaces for our vehicles, and for keeping your water catchment basin open to help drain the water from our flood-prone village. SM City Masinag has always been and will continue to be a treasure for the residents of Vermont Park Executive Village of Antipolo.”

Sustainability and resilience are at the core of SM Prime’s business strategy. The company invests significantly in these measures, recognizing that the benefits – safer communities, environmental protection, and enhanced business continuity – far outweigh the costs. SM Prime remains committed to building a more resilient future for the communities it serves.

SM City Baguio’s rainwater treatment facility: A model for water sustainability

· Leave a comment ·

The rainwater treatment facility (RTF) of SM City Baguio utilizes a rigorous six-step treatment process with real-time monitoring, ensuring processed water always adheres to potability requirements.

SM City Baguio is making significant strides in water stewardship with its innovative rainwater treatment facility (RTF), launched in July 2023. In the months since, the facility has already processed over 17,111.80 cubic meters of rainwater – equivalent to 7 Olympic-size swimming pools, or enough to fill over 6,800 standard water tankers – into potable water for the SM mall’s operations and for their lessees’ use.

This initiative supplements the mall’s water supply from the Baguio Water District and significantly contributes to the city’s water security and the safety of its residents. Located at the mall’s basement level, the RTF provides 30% of the mall’s total monthly average requirement for clean water that is safe for consumption and food preparation.

“There is a critical need for reliable and safe water sources,” said Baguio City Mayor Benjamin Magalong. “And SM City Baguio’s rainwater treatment facility is a commendable initiative that directly addresses this need. We hope that other private establishments can adopt similar projects for the efficient use of our water resources.”

The RTF utilizes a meticulous six-step treatment process, with equipment monitored and parameters checked in real time to ensure optimal performance. The processed water undergoes regular testing by the city’s accredited testing facility and consistently passes all water potability standards.

“This facility is a testament to SM Prime Holdings‘ commitment to sustainable operations and to the well-being of the communities we serve,” said Engr. Liza Silerio, SM Supermalls’ Vice President and Sustainability and Resilience Head. “By maximizing rainwater harvesting and treatment, we are not only reducing our reliance on the city’s water supply but also contributing to a healthier and more resilient Baguio City.”

The impact of the RTF extends beyond the mall itself. With reduced reliance on the city’s water supply, water haulers have been able to service more households, particularly during periods of water scarcity experienced throughout the city.

SM City Baguio’s rainwater treatment facility stands as a shining example of how businesses can play a vital role in addressing critical community needs through innovative and sustainable solutions.

SM Prime remains committed to its role as a catalyst for economic growth, delivering innovative and sustainable lifestyle cities, thereby enriching the quality of life of millions of people. SM Prime is pursuing the next horizon in integrated property development and onward to building sustainable cities of the future.
