COVID-19 - Wastewater Treatment is Designed to Destroy Virus

You may have heard or read that coronavirus has been detected in raw sewage in communities where the virus is present.

Today’s wastewater treatment systems use multiple, advanced filtration, and disinfection processes to treat the water.  These processes are designed to specifically remove or kill pathogens, including viruses such as the novel coronavirus. It is also known that the coronavirus is particularly susceptible to disinfection.

As asserted by the California State Water Board: “Existing stringent state standards protect public from COVID-19.” That agency also says, “There is no evidence that COVID-19 survives the disinfection process for drinking water or wastewater. California’s comprehensive safe drinking water standards include disinfection processes for drinking water which are extremely effective against viruses, including coronaviruses such as COVID-19.”

In our future Pure Water Soquel treatment process, after standard treatment including tertiary treatment, the virus would be eliminated at the wastewater treatment plant before being sent to our new advanced purification facility. Our advanced purification process would provide even further assurances of clean, safe water through the use of reverse osmosis filtration and ultraviolet (UV) / advanced oxidation process (AOP) treatment steps.

The reported detection of the coronavirus in untreated wastewater is something that continues to be methodically and comprehensively studied by expert scientists at agencies including the California State Water Resources Control Board/California Environmental Protection Agency, the World Health Organization, the US Environmental Protection Agency, the Centers for Disease Control, and the Water Environment Federation.

Pandemics like COVID and natural disasters like the recent wildfires, make water quality a high priority for water agencies and we will continue to follow guidelines by the state and federal water quality regulators.
