WATA technology contributes to the autonomy of health centers in the management of their sanitation, especially in remote areas.
It allows the production of sodium hypochlorite, a multipurpose disinfectant, useful for:


Surfaces, equipment, floors, bedding


in Dakin water

Drinking WATER



    • On-site production
    • Quantity and concentration of chlorine adapted to the needs
    • Solar power system technology



  • Training of health personnel
  • Easy to use
  • Adoption of technology and hygiene practices by medical staff

Durable and Sustainable

    • Limits pollution from logistics
    • Long-term investment:
      Our devices have a lifespan of at least 10 years

By improving hygiene conditions and water quality, WATA contributes concretely to Sustainable Development Goals 3 “Good Health and Well-Being” and 6 “Clean Water and Sanitation”, by improving health center care and drinking water treatment.



In developing countries:

1/4 of the health centers have no access to running water.

– This means that 712 million people have no access to safe water at all when seeking medical care.

2/3 of countries do not have dedicated budgets to improve their national water strategies and inequalities are particularly high in the least developed countries.

Without water, it is difficult to ensure hygiene and this is compounded by the lack of access to disinfectant.

In the health sector, access to chlorine as an antiseptic improves the quality of care by enhancing hygiene. Good environmental disinfection also reduces the risk of nosocomial diseases (infections transmitted in hospitals)*¹.

In rural health centers, chlorine is often unavailable or of poor quality. This is often due to unreliable logistics.


*¹ S. Pereira, 2014, Disinfection with sodium hypochlorite in hospital environmental surfaces in the reduction of contamination and infection prevention: a systemic review



Sodium hypochlorite is mentioned in the WHO guidelines for preventing SARS-CoV-2 infections. The external structure of corona viruses makes them not resistant to this type of disinfectant.

In hospitals, many areas must be disinfected at least twice a day with a 0.1 % concentrated solution. Floors and surfaces touched by human secretions or blood require a concentration of 0.5 %.

In households with a suspected or confirmed case of COVID-19, contact areas such as bathrooms, door handles, etc., should be sprayed with a 0.1 % concentrated solution.

Here are the full WHO recommendations


A study published in the Journal of Hospital Infection cross-referenced the results of 22 different studies and showed that sodium hypochlorite can disinfect surfaces in only a single minute, while the virus can remain for up to 9 days on an untreated plastic surfaces.

The Grand Sud region of Madagascar is the most landlocked and least developed area of the country (UNDP). 11% of the Malagasy population living there does not benefit from sufficient infrastructure or employment opportunities and are also affected by famines.

A solution to improve hospital hygiene has been implemented in 75 basic health centers (CSB), most of which have no access to electricity. The installation of solar-powered WATA electrochlorinators aims to increase the autonomy of the medical staff and reduce transmissions of nosocomial diseases. Produced locally, the active chlorine is used to disinfect surfaces and to make water safe to drink.

In 2020, the 11th outbreak of the Ebola virus disease was declared in the Democratic Republic of Congo (DRC). To limit the spread in Congo Brazzaville, which shares a 600 km river border with the DRC, 10 health facilities (FOSA) located in seven of the high-risk districts have been equipped with solar chlorine production units.

Reinforcement of hygiene standards in 26 health centers in 3 health districts of the country.
It is significantly more affordable to use a WATA device in this setting. Indeed, research shows that there are daily savings of up to 53 Euros when compared to traditional chlorine tablets.
