AguaClara Reach - Safe Water on Tap

AguaClara Reach transforms lives by enabling communities around the globe to have clean water on tap for life. We train partner organizations to design and deploy nonelectric municipal-scale water treatment systems -- life-giving technologies that are affordable, disaster-resilient, and can be operated independently by under-served towns and villages.

Two billion people lack access to clean drinking water around the world, and 2 million people die every year due to waterborne disease. Conventional water treatment plants fail to alleviate the problem: they are complex, costly, and have an expected lifetime of no more than 2 years in underdeveloped communities. AguaClara plants are built using locally-available materials by local labor, can be operated by a person with a 6th grade education, and are powered by gravity. Thus, they can be operated and maintained independently by the communities they serve for decades at a time.

The AguaClara program was started as a student-based research program in 2005 at Cornell University. This program launched the first AguaClara plants in Honduras, of which there are 14 today, serving 65,000 people in total. In 2013, the certified B-corporation AguaClara LLC was founded to help provide the on-site support required to pilot and scale the systems throughout the world. AguaClara LLC implemented 4 water treatment plants in India, serving 2,000 people in total and was listed on B-Corp’s Best for the World Overall in 2015 and 2017. In the summer of 2017, AguaClara Reach was founded as a New York state nonprofit (501(c)3 pending) to aide in our ability to better serve the under-served.

AguaClara plants are the only 100% community-scale gravity-powered water treatment solutions that are sustainable in towns and villages. When a community has 24-hour water supply available to them via household tap, there is an immediate reduction in incidence of waterborne disease. As a result, adults have more productive working days, and children -- especially girls, who bear the burden of collecting water from distant sources for the household -- have higher attendance in schools. Women spend the time saved in childcare, reducing child mortality, or to participate in leadership roles in the community, giving them greater representation in the local democratic process.

AguaClara plants cost half as much to build as conventional mechanized treatment plants and one third as much to operate. Plants are built using widely-available materials, such as cement, sand, PVC, and brick, making them inexpensive to built and enabling communities to carry out repairs independently. The plants do not require any electricity to run, meaning the operational cost is mainly that of the local community operator. It costs between 1-5 USD per household per month to provide 100 liters of water per person per day, while also allowing local water boards to save money for future upgrades and repairs.

AguaClara plants utilize key technologies developed at Cornell University that make them simple, affordable, and high performing:

1. A hydrodoser that delivers chemicals at an accurate dose to raw waters that may fluctuate in flow rate without using electronics, sensors, or pumps. It automatically turns on and off with the flow of raw water,

2. A self-cleaning sedimentation tank that produces a floc blanket capable of treating water to World Health Organization standards for turbidity for drinking water prior to filtration, and

3. A stacked rapid sand filter that requires 80% less area to build and wastes 80% less water than a conventional rapid sand filter. The operator can easily backwash it, without using clearwells or pumps, by opening and closing a half-inch valve.
