THINK RAIN! All the clean, safe drinking water you need from RAIN...



Water Charity – Bank On Rain

Our mission is to establish “ecosystems” in developing countries. This not only provides communities with clean water for consumption and agriculture, but also creates a framework for an improved and continuing quality of life.

As a water charity, we provide the tools and the continuing education to establish and maintain the benefits that safe sanitation and clean drinking water brings; opening up future opportunities, developing local business and commerce.

Bank On Rain, founded in 2008, is a 501(c)(3) incorporated in the State of Washington (USA) 2010, and operates globally.

Our small & nimble team can move fast, implement multiple projects at one time, share our expertise, and/or partner with others to help them implement their projects. Being small and nimble also keeps our administrative costs extremely low.
