The Challenge

Cooling Takes Water

Cooling towers lose water through evaporation, drift and blowdown, creating a continuous need for make-up water. For data centers and other critical facilities, reducing this demand is becoming increasingly important.

Recovering Water in Las Vegas

SNWA, MGM Resorts International, F1 Las Vegas and WaterStart partnered to pilot Watergen technology at the MGM Grand — capturing humidity from the cooling towers’ exhaust and turning it back into water for the system.

The Opportunity

What if Cooling Water Could Be Recovered?

Watergen is developing an innovative approach to recovering water associated with cooling operations — helping reduce dependence on conventional make-up water.

Recovery scheme: hot moist air captured above the cooling tower travels through an insulated duct to a GEN-L, which condenses the vapor back into water and returns it to the tower as make-up water
  • 1 × GEN-Lducted to the cooling-tower exhaust.
  • ≈ 6,000 L / day≈ 1,585 US galcondensed back into the loop as make-up water.
  • ≈ 10%of a small tower’s daily use — each added GEN-L returns another ≈ 10%.

Not just recovered — better water for the loop.

Atmospheric water is virtually mineral-free, comparable to distilled — and what never enters the water can’t leave limescale or corrode the system:

  • Ca2+No limescale
  • Mg2+No deposits
  • Cl−No corrosion

Why Watergen?

Reduce demand on one side, generate capacity on the other.

  • Water recovery

    Captures humidity associated with cooling operations and turns it back into usable water.

  • Reduced make-up water demand

    Every recovered liter is a liter your towers don’t need to draw from conventional supply.

  • High-capacity generation

    Industrial-scale atmospheric generation — up to 6,000 liters a day from a single unit.

  • Engineered for industrial applications

    Designed to run continuously in demanding environments, alongside the systems it supports.
