Every year over 842,000 people die from waterborne diseases. That’s why we developed WATA™: a local and affordable way to disinfect and treat water.

Using only salt and water, WATA™ technology produces active chlorine locally and at low cost.

The injection of active chlorine into drinking water eliminates 99.9% of the pathogenic microorganisms that it contains. That’s why, according to the WHO, producing chlorine on site is a simple, low-cost and sustainable solution to improve access to drinking water.


  • The only things you need are water, salt and energy (mains or solar)
  • Local, independent production process
  • No logistics

Low cost

  • 1 litre of WATA™ chlorine = 3,300 litres of treated water
  • $0.05 / 1,000 litres of drinking water
  • One device = several possible applications


  • Complete ‘Plug-in & play’ kit
  • Low maintenance
  • Very easy to use
