Where We Operate
Gravity Water currently focuses its efforts in the Asia-Pacific Region, with established operations in Nepal and Vietnam. Over the next six months, Gravity Water is expanding pilots to Taiwan, Malaysia, and Indonesia through corporate support.

Today, billions of people lack access to a safe and reliable source of water. Climate change is making this challenge an up-hill battle, reducing water security and safe water access for urban cities, last-mile communities, and everywhere in between.
Gravity Water's intervention helps schools keep water in the ground and provide safe drinking water to students for under $1 per child per year. Gravity Water is currently scaling its impact to benefit public infrastructure throughout the Asia-Pacific region, with a focus on at-risk communities.
As water patterns become less reliable and dependency on water increases, finding ways to keep water in the ground is critical. Gravity Water believes the solution is found in using rain as an integrated practice of daily life and a common water source for rural and urban areas.
Gravity Water is currently transitioning from a singular focus on safe drinking water at schools to a holistic focus on water security for all public and private infrastructure. Gravity Water is working on a moonshot to bring rainwater harvesting to one million structures by 2030 through a collaborative funding model.
Our Technology and Approach
Gravity Water focuses on a low-technology approach to safe and sustainable water access through combining rainwater harvesting, elevated storage, and gravity-fed filtration.
On average, our projects provide schools with enough rain to fulfill over 50% of their water demand each year.
Our filtration technology removes taste, odor, metals, chemicals, parasities, and >99.9% of pathogens that cause water-related illness.
Gravity Water helps schools operate more efficiently by centralizing their water system and providing water conservation tools.
Collaborative Data Collection
Transparent data collection, monitoring, and reporting, allowing continuous insight on the effectiveness of the organization's solution.
Support Our Work
Gravity Water's technology can provide safe drinking water to a child in need for less than $1 per child per year, over a 12-year period. This includes a one-time $8 per child cost to install a Gravity Water system, and a $0.20 per child per year ($50-$60 per school per year) recurring cost for filter replacements and maintenance.
