→‎Construction, operations and maintenance

If the electrolysis is occurring properly, bubbles are formed immediately. The electrolysis takes an hour per litre, producing a chlorine concentrate of 6g/L. The chlorine concentrate should be used within three weeks of production. Notable is that full containers last longer than half-empty ones, due to the effects of dissolving oxigen.

'''=====Use'''=====

The chlorine concentrate is then added to the water to be disinfected. It should be shaken thoroughly and left for 30 minutes. There should be 0.5-1.0mg/L of residual chlorine left. The level of chlorine can be measured using the WATAblue reagent.

====Estimated Lifespan====

The WATA device is expected to operate for about 20,000 hours. If used for 12 hours a day, 7 days a week, it would last about 4.5 years.
