Parent company Fondation Antenna
From Switzerland
Maturity stage TRL 9 / CRI 3-4 - Commercial Scale Up / Multiple commercial Applications

Sodium hypochlorite is among the most widespread water treatment solutions, killing most pathogens and thus excellent at fighting waterborne diseases. 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.

The Environmental Benefits

  • A range of devices to produce between 500 mL and 60 L of active chlorine in 2 hours. 1 L of active chlorine can treat 3,300 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.

The Financial Benefits

  • 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.
