WATA™ technology

Devices to locally produce sodium hypochlorite for water treatment and disinfection purposes

A range of electro-chlorination devices that require only salt, water and a source of energy (grid or solar) to produce active chlorine for remote and rural areas.

Sodium hypochlorite is among the most widespread water treatment solutions, killing most pathogens and thus excellent fight waterborne diseases. And when used according to a specific dilution matrix it can also be applied for disinfecting equipment, surfaces, clothes or even food. WATA’s technology can improve hygiene and sanitation and help provide a clean water source, bringing significant benefits to rural healthcare facilities with limited access to disinfectants and potable water.

Key features for a positive impact on quality of life

  • A range of devices to produce between 500 mL and 60 L of active chlorine in between 3 and 4.5 hours. 1 L of active chlorine can treat 8,000 L of water
  • Local production of potable water and disinfectant.
  • No CO2 emitted into the atmosphere by the device when operating, a good replacement for boiling water over a wood-burning stove.
  • Sturdy device, adapted to suit field work.


  • Treat 4,000 L of water at a cost of USD 0.06, saving USD 2.00 per day instead of chlorine tablets.
  • Facilitated access to disinfectant and clean water leads to improved sanitation and lower healthcare expenditures.
