Better water solutions
for builders, people, and planet

Natural systems to treat and reuse water at any scale.

Builders need water conservation solutions that add value to homes

  • Higher valued homes and landscapes
  • Meet water conservation regulations
  • Lower development and utility costs
LeapFrog Design's EstuaryTM 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.

LeapFrog water reuse technology helps builders

The Estuary is an all-natural, plant-powered water treatment system that adds beauty to outdoor spaces as it recycles water from sinks, showers, and washing machine for reuse in toilet flushing and irrigation.
