WATA™ technology - Devices to enable local treatment and disinfection of water

A range of electro-chlorination devices requiring only salt, water and a source of energy to produce potable water and disinfectant for remote and rural areas

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.
