From the time she found her way to an indigenous village in the Peruvian Amazon during a trip to “access a deeper knowing” in her life in 1999, this former Los Angeles fashion and advertising photographer’s commitment to improving the health of children and families in the Manu Biosphere Reserve and National Park has only grown stronger.
Nancy’s can-do spirit, positivity, love of nature, and seeing the good in people, are the heartbeat of Rainforest Flow. They are the driving force that has guided the organization’s vision for more than 20 years.
After piloting a successful 5-year culturally integrated water, sanitation, health, and technical and vocational training programs in the indigenous village of Huacaria, Nancy scaled and replicated the program in three additional communities.
Under Nancy’s guidance, Rainforest Flow has positively impacted the health of three generations of indigenous people in Peru’s Amazon rainforest.
She attributes much of her perseverance to lessons learned from her daily paper route and growing up after school at the Girls Club of America in Bristol, Connecticut, the generosity of mentors along the way, and the love of her close-knit Italian family.
Nancy’s sights are now set on building a permanent physical home for The Rainforest Flow WASH Education + Research Center (WERC) in the rainforest. The Center will be a gathering place for indigenous people to learn and share information, to become stewards of the health of their communities and environment.
Nancy spends half of her life in the rainforest and most of the rest collaborating with donors, community organizations, anthropologists, health experts, engineers, and technology partners to realize this Center, and her dream to help tens of thousands of indigenous people gain access to life-giving human services.
A Peruvian board member, master builder, hydraulic expert, and self-taught engineer, Caleb’s love of indigenous rainforest cultures and his keen workmanship are the foundation for all our projects.

We deliver clean, safe water to indigenous people in rainforest villages. We capture the water from natural springs and purify it using rock and sand filters in portable geomembrane treatment tanks. Where topography permits, we distribute water by gravity feed to homes, schools, and health posts. In flatter terrain, we build rainwater harvesting systems to supply safe water.
We provide ongoing technical training to the village Water + Sanitation Committees (W+S). In time, villagers learn to maintain, repair, and expand their water and sanitation systems on their own, guaranteeing the sustainability of the program. Community members also learn to monitor water quality using the Hach portable microbiology lab, which helps to ensure safe drinking water.
W+ S Committee members and families work with us to gather rock, sand, wood, and other natural materials from forests and rivers. Together we build durable, practical sinks at homes and village schoolhouses. The sinks are built with underground greywater drains to avoid environmental contamination. We teach families and schoolchildren how to maintain their sinks and drains.
We build eco-friendly bathrooms with biodigester waste management tanks that do not contaminate the ecosystem. School bathrooms are well ventilated, easy to clean, and have separate sides for boys and girls. We are now piloting individual household bathrooms using the same technology.
We provide hygiene education, coronavirus prevention, and health monitoring to village families and schoolchildren. Community members who take a special interest in our program are trained as Health Promoters who monitor health and hygiene in their villages and share information with nearby villages.
Our health and anthropology team conducts baseline studies to monitor long-term health and social impacts. We track parasites, anemia, malnutrition, and gastrointestinal diseases before and after our intervention. This data helps us to measure health outcomes, adapt our programs, and inform health and government agencies.

Nuestras tecnologías proveen de agua limpia y segura a comunidades indígenas en la Amazonia. Captamos el agua de manantiales naturales y la purificamos mediante filtros compuestos de piedras y arena en tanques portátiles de geomembrana. Donde la topografía lo permite, distribuimos el agua por gravedad a hogares, escuelas y puestos de salud. En terrenos más llanos, construimos sistemas de recolección de agua de lluvia para suministrar agua segura.
Brindamos capacitación técnica permanente a los Comités de Agua y Saneamiento (JASS) de las comunidades. Con el tiempo, los comuneros aprenden a mantener, reparar y ampliar sus sistemas de agua y saneamiento por su cuenta, lo que garantiza la sostenibilidad del programa. Los miembros de la comunidad también aprenden a monitorear la calidad del agua utilizando un laboratorio portátil de microbiología de marca HACH, que ayuda a garantizar el agua segura para consumo.
Los miembros del Comité JASS y sus familias trabajan con nosotros para recolectar piedras, arena y otros materiales naturales de los bosques y ríos. Juntos construimos piletas durables y prácticas en las casas y escuelas. Las piletas están diseñadas con zanjas de infiltración subterráneas como desagüe para las aguas grises, evitando la contaminación ambiental. Enseñamos a las familias y escolares a mantener sus piletas y desagües.
