The WATA® device makes use of the simple process of electrolysis to produce sodium hypochlorite at a concentration of 6 grams per liter using only salt and water as inputs. As the active chlorine has a strong oxidizing power, it effectively inactivates the vast majority of disease-causing bacteria and viruses.
Active chlorine solution is being produced using the WATA® range of devices in over 100 countries. It reaches people in need through local NGOs and community groups, international organizations, municipal authorities and private enterprises. Since the WATA® range of devices was first launched in 2009, Antenna Foundation is hoping to expand their reach further through partnerships, especially with local enterprises. The WATA® devices have also been incorporated into development programmes led by other organizations.

====The WATA Range of Devices====
[[Image:Range of WATA devices.png|thumb|right|200px| [https://www.antenna.ch/en/water-hygiene/guinea/ The WATA® range of devices]]]
The device comes in five models for different scales of chlorine production: Mini-WATA® (0.5L of solution), WATA-Standard® (2L of solution), WATA-Plus® (15L of solution), Midi-WATA® (30L of solution) and Maxi-WATA® (60L of solution). The Mini-WATA®, the WATA-Standard® and the WATA-Plus® are all capable of running off of a solar energy source allowing them to be deployed in regions that lack stable access to electricity. The devices take between 2.5 & 4.5 hours to convert the brine solution to active chlorine solution. Once the process is finished, one litre of that solution is good for disinfecting 4,000 litres of water.
=====Operation=====

The device should only be used by adults. The user guide should be carefully read before use. The chlorination however should be supervised by a qualified person.
====Use for Water Disinfection====

When sodium hypochlorite is added to water the active chlorine is involved in three separate reactions:
*Active chlorine reacts through oxidation with organic matter and pathogens in the water and kills them. This portion is called consumed chlorine.
