About Aqua4™ Technology:

Aqua4™ is an “engineered aquifer” for reliably producing freshwater when and where it’s needed. At its core, Aqua4™ is a Concentrated Solar Still (CSS), a proven technology for optimizing freshwater production from any source of treatable water. The system uses solar thermal energy to evaporate and distill water at 30 times the efficiency of natural evaporation. Unlike simple stills, the Aqua4™ CSS uses advanced absorption technology to dramatically increase production. A single Aqua4™ module generates 65,000 gallons of freshwater per day – 70 acre-feet per year – from wastewater, drainage water, runoff, saline groundwater and industrial process water. The remaining brine is concentrated into solid byproducts for resale.
