SM Turns to Rainwater Harvesting a Key to Living Flood-Free
- Rainfall is often seen as a foe by Filipinos who face about 20 typhoons a year causing disruption and mass evacuations, but it can also be a friend as rainwater can be a solution to help address water scarcity.
- SM turns rainwater from a foe to a friend by building rainwater catchments in its malls to harvest large volumes of rainwater, particularly in flood-prone areas, helping keep neighboring communities to be safe and flood-free.
- 20 SM malls can catch and store a total of 79,257 cubic meters of rainwater, equivalent to almost 32 Olympic-size swimming pools
Climate change is real and Filipinos are among those who can attest to the devastating effects it brings to everyday life. Faced with about 20 typhoons a year, the Asian Development Bank reported that the total impact from storms have reached about US$20 billion from 1990 to 2020. It causes a temporary disruption due to mass evacuations which bring about an average of 2-8% reduction in gross domestic product annually.
Despite the reoccurring devastation felt during calamities, Filipinos still manage to see the humorous side of life and are often reported as one of the happiest people in the world. However, this may soon be tested as, according to the latest report of the UN Intergovernmental Panel on Climate Change, things are about to get worse as the planet heats up, accelerating the effects of climate change and making the Philippines more vulnerable to drastic changes in weather patterns.
On average, the Philippines receives about 2,400 millimeters of rainfall each year, one of the highest in the world. While this poses a problem for the country, there is a silver lining, as it can also be the solution for water scarcity. However, currently the Philippines only harvests around 6% of its rainwater compared to India which harvests around 60% of the 700-millimeter average rainfall it receives each year.
Rain Water – a friend or a foe?
Water is a scarce resource. The United Nations Sustainable Development Goal number 6 identifies access to clean water as one of the global priorities to be achieved by 2030. Aligned to its environmental responsibility programs, SM takes a closer look at the use of water and how it can be turned from a foe to a friend.
SM builds its malls and integrated lifestyle cities with resilience and sustainability in mind. Understanding the value of water, SM builds rainwater catchments in its malls to harvest large volumes of rainwater particularly in flood-prone areas.
“We approach it two ways: resilience – to help communities be flood-free; and sustainability – to optimize water which is a scarce resource so we can use it for other purposes rather than just waste it,” says Architect Fides Garcia-Hsu, Vice President at SM Engineering Design and Development.
Vermont Park and Vermont Royale are two communities that once saw rain as a foe. Every time it rained, their neighborhoods ended up underwater, damaging their homes. Today, homeowners welcome the rain as water that can be harvested and stored for future use. The reason? SM City Masinag’s rainwater catchment facility! It has a 17,681 cubic meter water capacity. The two communities connected their drainage systems to the mall which is equipped with three 30HP submersible pumps which are used to pump out accumulated rainwater.
“Wherever SM is, we try to help our communities become resilient to changing weather patterns,” explains Arch. Garcia-Hsu. “Nationwide, we have 20 malls equipped with rainwater catchment facilities that help rainwater management to avoid flash floods for surrounding communities.”
As a company, SM invests 10% of its capital expenditure to integrate disaster resilient and sustainability features in its malls and integrated lifestyle city designs. “We take a long-term view on resilience and when we talk about sustainability, we look at how we can address perennial problems like flooding and address systemic change,” Arch. Garcia-Hsu expounds.
Serving as pioneers in the installation of rainwater catchment facilities, SM was instrumental in the passing ordinances and inclusion of the installation of water catchment facilities for developments by regulatory bodies. In recent years, Senator Manny Pacquiao passed the ‘Rain Water Harvesting Act – Senate Bill 1309’ mandating the establishment, maintenance, and management of rainwater harvesting systems in the country.
“Aside from building resilient infrastructure, we also build the resilience of our stakeholders by providing disaster preparedness training through our SM Cares programs,” shared Chito Bauzon, SM Cares Marketing Asst. Vice President. “We have programs targeted to senior citizens and those with special needs as they are the ones left most vulnerable during times of calamities.”
With the threat of climate change looming, typhoons are only expected to get stronger with intensified rainfall. With more Filipinos moving to urban centers, the Philippines will need to retrofit its cities for resiliency or build new sustainable cities to finally live flood-free.
