Currently The COVID-19 virus has not been detected in drinking water. Conventional water treatment methods that use filtration and disinfection, such as those in most municipal drinking water systems, should remove or inactivate the virus that causes COVID-19. There is no evidence that COVID-19 can be spread to humans through the use of pools and hot tubs. Proper operation, maintenance, and disinfection (e.g., with chlorine and bromine) of pools and hot tubs should remove or inactivate the virus that causes COVID-19.

Based on current evidence, the risk to water supplies is low. Laboratory studies of surrogate coronaviruses that took place in well-controlled environments indicated that the virus could remain infectious in water contaminated with faeces for days to weeks. A number of measures can be taken to improve water safety, starting with protecting the source water; treating water at the point of distribution, collection, or consumption; and ensuring that treated water is safely stored at home in regularly cleaned and covered containers.

The CDC is reviewing all data on COVID-19 transmission as information becomes available. At this time, there is no evidence that shows the transmission of virus that causes COVID-19 through sewerage systems has occurred, although it is possible. This guidance will be updated as necessary as new evidence is assessed. Data suggest that standard municipal wastewater system chlorination practices may be sufficient to inactivate coronaviruses, as long as utilities monitor free available chlorine during treatment to ensure it has not been depleted. Conventional, centralized water treatment methods that use filtration and disinfection should inactivate the COVID-19 virus.

With an infrastructure in steep decline it is imperative that we safe guard our water systems to ensure a water supply free of any pathogens or contaminants. The standard water treatment systems for a borehole can also be installed at the point at which municipal water enters the property.
