Rainwater facility contributes to sustainable water supply

SM City Baguio’s commitment to water conservation is evident in its innovative rainwater treatment facility (RTF). Since its launch in July 2023, this system has successfully 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.

The RTF, located at the mall’s basement level, supplements the mall’s water supply from the Baguio Water District. By providing 30% of the mall’s total monthly average requirement for clean water, the facility helps alleviate the strain on the city’s water resources, especially during periods of scarcity.

“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.
