Rainmaker 330 Solar Water Distiller from SolAqua uses evaporation to create natural pH buffering to produce pure, clean water.


  • Zero energy use


  • Solar stills

UN Sustainable Development Goals Addressed

  • Goal 3: Good Health & Wellbeing

  • Goal 6: Clean Water & Sanitation

  • Goal 11: Sustainable Cities & Communities

The Challenge

Distillation processes that use steam, electric, or boiling techniques require large amounts of energy and can also leave purified water with a flat taste.

Innovation Details

The Rainmaker™ 330 is a solar still that collects rain and transforms it into clean drinking water. It uses the process of natural evaporation and condensation to allow for natural pH buffering that produces clean, excellent tasting water.

Biomimicry Story

Evaporation is the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary way that water moves from the liquid state back into the water cycle as atmospheric water vapor. Studies have shown that the oceans, seas, lakes, and rivers provide nearly 90% of the moisture in the atmosphere via evaporation.
