SM City La Union Boosts Climate Resilience with Rainwater Catchment System

With climate change driving heavier rains and more frequent floods, proactive flood prevention has become a key part of building resilient communities.

The newly opened SM City La Union becomes the 30th SM mall to install a rainwater catchment system, supporting thousands of residents in flood-prone areas and demonstrating how business innovation protects communities.

SM City La Union, now the 30th mall of SM Prime Holdings, Inc. (SM Prime) that features a rainwater catchment facility, expands its network of climate-resilient infrastructure nationwide. For SM Supermalls, catchment facilities are designed to collect and store large volumes of stormwater, preventing runoff that could otherwise overwhelm drainage networks.

During heavy rainfall, the catchment temporarily holds stormwater, allowing gradual discharge through proper channels. Collectively, SM City La Union’s underground rainwater catchment system can provide a total capacity of 760 cubic meters.

A design for tomorrow. SM Supermalls focuses on sustainable water use by managing available resources to meet the needs of future generations.

Each drop contributes to a safer, more sustainable future for all. Mapping every opportunity to achieve Water for Tomorrow, treating and reusing water as a supplemental water source also significantly decreases freshwater consumption. In 2024, SM Prime achieved a 26.23% increase in recycled water volume, rising from 4.42 million cubic meters in 2023 to 5.59 million cubic meters.

Social resilience is equally important as the physical infrastructure. SM Cares raises awareness on water conservation and adopting sustainable practices in daily life, helping to empower community action. 

“Our rainwater catchment systems go beyond flood control — they help create safer spaces for our communities. We hope to show how climate-smart infrastructure and innovation can protect lives, livelihoods, and progress,” said SM Supermalls President Steven Tan.
