Coronavirus in drinking water or wastewater.

The Coronavirus is spread through contact with other people. The COVID-19 virus has not been detected in drinking water plants. According to current evidence (March 20, 2020), the risk of contamination in the drinking water supply is low. So there is no risk of using water as we have done so far.

The coronavirus, COVID-19, "is not robust", it is less stable in the environment and therefore it is very susceptible to oxidants, such as chlorine or ozone, or the disinfection methods we use.

The World Health Organization WHO said there is no evidence on the survival of the COVID-19 virus in drinking water or wastewater, adding that the two main routes of transmission are respiratory or contact.

Is it safe to drink water?

The EPA recommends that you continue to use and drink water as usual. But for Mexico it is essential to do it with a bacteriological treatment, not for Coronavirus, but for other pollutants of municipal water.

The World Health Organization (WHO) has stated that "the presence of the COVID-19 virus has not been detected in drinking water supplies and, based on current evidence, the risk to water supplies is low." Also, according to the CDC (Centers for Disease Control and Prevention), COVID-19 is believed to spread primarily between people who are in close contact with each other. EPA regulations on drinking water require treatment in public drinking water systems to eliminate or eliminate pathogens, including viruses.

Do I need to boil my drinking water to make it drinkable?

It is not necessary to boil water as a precaution against COVID-19.

Is it safe to use tap water to wash my hands?

The EPA mentions that we can continue to use drinking water for our personal hygiene as we do today. According to the CDC, wash your hands often with soap and water for at least 20 seconds Helps prevent the spread of COVID-19.

Treatments that municipal drinking water systems can include: filtration and disinfectants such as chlorine that remove pathogens before they reach the tap.

If you have supply from private wells, you may consider treatment by chlorination or disinfection systems by ozone or ultraviolet light, eliminate bacteria, viruses and other pathogens.

Can I get COVID-19 from sewage?

The WHO has indicated that "there is no evidence to date that the COVID-19 virus has been transmitted through sewage systems, with or without wastewater treatment."

Do Wastewater Treatment Plants Treat COVID-19?

Yes, wastewater treatment plants treat viruses and other pathogens. COVID-19 is a type of virus that is particularly susceptible to conventional disinfection. Standard treatment and disinfection processes in wastewater treatment plants are expected to be effective.

Could my septic system treat COVID-19?

While private sewage systems (i.e., treated septic tanks) do not fully disinfect, the EPA hopes that a properly operated septic system will not spread COVID-19 in the same way as other viruses commonly encountered. in sewage. In addition, when properly installed, a septic system is located at a distance and location designed to avoid impacting a well that supplies potable water.

Specific COVID-19 protections are not recommended for employees involved in sewage plant operations, the Water Environment Federation (WEF) said. Workers must follow routine practices to avoid exposure to wastewater.

Transmission through feces

The Federation (WEF) mentions that COVID-19 can be transmitted through the fecal-oral route. The RNA virus was detected in the feces of patients after scientists noted that some patients infected with the COVID-19 virus experienced diarrhea in the early stages of infection rather than fever, the latter being more common.

The CDC mentioned that it "does not know the risk of transmission of COVID-19 from the feces of an infected person." However, it added, the risk is expected to be low based on data from previous outbreaks of related coronaviruses, such as SARS and the Middle East respiratory syndrome (MERS). To date, there have been no reports of fecal-oral transmission of COVID-19, the CDC added.
