Plant-powered water for all

Natural systems to treat and reuse water at any scale.
LeapFrog Design's plant-powered ecological water reuse treatment systems capture water from sinks, washing machines, and showers; clean it just like nature would; and then make it available for toilet flushing and irrigation.

Beautiful, Green, Scalable Water Reuse

LeapFrog Design's EstuaryTM is a plant-powered ecological water treatment system. On the surface, a modern planter box full of vibrant plants adds beauty to your landscape. Inside, plants and microbes clean water from your sinks, showers, and washing machine for reuse in toilet flushing and irrigation.

Conserve water while adding luxury, beauty, and plants to your life.
