The facts about COVID-19 and drinking water
A technical brief from the World Health Organisation (WHO) was released in early March for water and sanitation practitioners and providers.
There is no evidence about the survival of the COVID-19 virus in drinking water or sewage, WHO said, adding that the two main routes of transmission are respiratory or contact.
As an enveloped virus, COVID-19 is “not robust”, less stable in the environment and is more susceptible to oxidants, such as chlorine.
Conventional, centralised water treatment methods that use “filtration and disinfection should inactivate the COVID-19 virus”, the Organisation added.
In areas where centralised treatment is not present, “household water treatment technologies” including boiling, or using high-performing ultrafiltration or nanofiltration filters, solar irradiation, and, in non-turbid waters, UV irradiation and appropriately dosed free chlorine”, should be used.
The Centers for Disease Control and Prevention (CDC) remarked that the COVID-19 virus has not been detected in drinking water.”
