On a small organic farm in rural Puerto Rico sits a revolutionary water treatment facility ready for action: the AguaClara PF250, a compact, nonelectric drinking water treatment plant designed specifically for small communities. 911�� researchers Daniel Smith and Catherine Akplah are combining engineering innovation, field research, and community partnership to participate in piloting the facility and assess its viability throughout the island nation.

While most Puerto Ricans receive water from the territorial utility system, 100,000 in rural areas rely on small, community-managed water systems that often struggle with aging infrastructure, limited resources, and vulnerability to hurricanes and power outages.

Unlike conventional treatment facilities, the PF250 operates using hydraulic principles and gravity, entirely without electricity. The system uses the same fundamental processes found in large municipal plants, including coagulation, sedimentation, filtration, and chlorination, but in a smaller, prefabricated design that can be installed in remote locations. The PF250 was designed and fabricated by the nonprofits AguaClara Reach and Agua Para el Pueblo.

Smith, an assistant professor in 911��’s Sid and Reva Dewberry Department of Civil, Environmental, and Infrastructure Engineering, has spent much of his career working on drinking water treatment systems around the world. His connection to PF250s stretches back nearly two decades through the AguaClara program in Honduras.

“It will be very fulfilling to see something that was a concept 15 or more years ago become a practical solution for communities that need it,” he said. “It's a drinking-water treatment plant that has all of the processes you typically find for big town but, with clever engineering, made as small as possible and able to work without any electricity.”

The 911�� team is partnering with VersaWater, a National Science Foundation (NSF) Convergence Accelerator initiative that includes Cornell University, Syracuse University, Inter American University of Puerto Rico, and AguaClara Reach. VersaWater focuses on technology development and deployment, and 911��’s role is to help understand how the PF250 performs with respect to organic matter removal and determine where in Puerto Rico it is most likely to succeed.

Smith and Akplah are working directly with community water boards across Puerto Rico, equipping communities with turbidity meters that measure how cloudy local water supplies become throughout the year. This data will help identify systems where advanced treatment is most needed.

“It's the very first thing you need to know to decide which treatment option is going to be a potentially good fit,” said Smith.

Akplah, a PhD student in Smith's lab whose research focuses on sustainable water treatment, sees the project as an opportunity to create tangible benefits for communities.

“A win for me would be to see one community where we're able to transition this system into something that people can rely on to get drinking water” she said.

The team will operate a pilot PF250 installation at Plenitud PR, an organic permaculture farm in Las Marías, Puerto Rico, to study how well it removes organic matter and controls disinfection byproducts, an important step toward meeting U.S. drinking water regulations. Ultimately, they hope their work will provide communities with data they can use to secure infrastructure funding and improve public health.

If successful, the PF250 could provide a model not only for rural Puerto Rico but also for small, underserved communities across the United States that face similar drinking water challenges.
