This page will be updated periodically with limited general information, specific water-sector technical information, WEF events information, and links to trusted sites for the most up-to-date official information.
What we know today
To date, the scientific community has found no evidence of viable COVID-19 virus in wastewater systems.
Current efforts to elucidate numbers of infections in the community and support public health surveillance have relied on detecting the virus in wastewater using molecular techniques that identify genetic material (RNA), but this method does not assess virus viability or infectivity. Further, there is currently no epidemiological evidence that wastewater is a route of transmission.
While there is still a lot we don't know, it appears that contracting COVID-19 through exposure to wastewater is unlikely.
WEF is continuing to work on the matter of wastewater worker protection from disease causing microorganisms and pathogens, in general — especially via aerosols — by forming a Blue Ribbon Panel to address the issue of required personal protective equipment and protective work and hygiene practices.
WEF will continue to post the latest information on this page. See also “Biological Hazards at Wastewater Treatment Facilities,” which is Chapter 8 of WEF’s Manual Practice No. 1, Safety, Health, and Security in Wastewater Systems (Sixth Edition).
From the U.S. CDC
Currently, there is no evidence that coronavirus survives the disinfection process for drinking water and wastewater.
- The COVID-19 virus has not been detected in drinking water.
- The risk of transmission through feces is expected to be low based on data from previous outbreaks of related coronaviruses, such as severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS).
- At this time, the risk of transmission of COVID-19 through sewerage systems is thought to be low.
No coronavirus-specific protections are recommended for employees involved in wastewater management operations, including those at
wastewater treatment facilities.
- Water resource recovery facility operations should ensure workers follow routine practices to prevent exposure to wastewater. These include using engineering and administrative controls, safe work practices, and personal protective equipment (PPE) normally required for work tasks when handling untreated wastewater.
- Water workers should
- wear appropriate PPE, which includes protective outerwear, gloves, boots, and goggles or face shield masks;
- wash their hands frequently; and
- avoid touching eyes, nose and mouth with unwashed hands.

Note: The information posted here is a summary of current knowledge about this emerging viral pathogen. The state of knowledge will evolve as additional investigation and research is conducted, so continuous review of reputable sources and websites is advised.
To help put the outbreak of coronavirus into perspective, WEF and its partner organizations have begun creating resources and compiling links to external sources that speak to the specific concerns of water sector workers. This list of articles, podcasts, webcasts, fact sheets and more will be updated as new materials are available.
Water Sector Coronavirus Assistance
During this unprecedented time responding to the coronavirus pandemic, it is our collective responsibility to help ensure worker safety and keep essential water and wastewater infrastructure operating. To aid water and wastewater utilities in protecting and maintaining public health during the coronavirus response, several water sector partners have extended offers to help.
U.S. EPA Provides Template for Essential Worker Documentation (April 3)
On March 27, U.S. EPA Administrator Andrew Wheeler sent a letter to governors in all 50 states, territories, and Washington, D.C., requesting that water and wastewater workers, as well as the manufacturers and suppliers who provide vital services and materials to the water sector, be considered essential workers and businesses by state authorities when enacting restrictions to curb the spread of coronavirus. To help aid in the implmentation of that process, EPA now has provided a template that state, localities, and water utilities can use to provide documentation to workers that are considered essential.

Accommodating Essential Water Services (March 31)
In recent days, state and federal regulatory groups have made several temporary policy changes that recognize the water sector’s critical role in protecting public health during the coronavirus pandemic. These changes relax certain restrictions, such as temporarily honoring expired operator certification credentials or forgiving missed consent decree deadlines, that could otherwise impede a water resource recovery facility’s (WRRF’s) ability to respond locally to coronavirus in the most effective way possible.
Pulse Check – WEF Poll Finds Utilities Confident in Operations, Changing Work Arrangements (March 31)
With the water sector protecting public health throughout the coronavirus pandemic, WEF administered a quick, informal poll to gain some insights into how this situation is effecting the water workforce. The results were collected between March 23 and 28.
Experts Share Advice on Continuity of Operations During Coronavirus Pandemic (March 27)
For utility managers, effectively responding to coronavirus requires additional attention to employee safety and welfare, workplace hygiene, and public communications.

EPA Deems Water Workers Essential (March 27)
On March 27, U.S. EPA Administrator, Andrew Wheeler issued a letter to state governors requesting that water and wastewater workers, as well as the manufacturers and suppliers who provide vital services and materials to the water sector, be considered essential workers and businesses by state authorities when enacting restrictions to curb the spread of COVID-19.
Words On Water #134: Des Moines Water Works Shelters-In-Place to Respond to Coronavirus (March 27)
Ted Corrigan is interim CEO and General Manager and Kyle Danley is Director of Water Production at Des Moines Water Works. In this podcast, Ted and Kyle explain how the utility responded to coronavirus by activating a long-standing response plan and having essential staff shelter-in-place at its three treatment facilities. They discuss how 20 employees will stay onsite for two week rotations, working 12-hour shifts, seven days a week to provide clean water and sanitation for 500,000 people in central Iowa. Ted and Kyle say the staff understand they are serving in a public health role and helping their community, and that support is strong from external staff, the utility’s board, and the union.
Blog: What We Know About Coronavirus and Water Treatment (March 26)
This blog by Rasha Maal-Bared, Senior Microbiologist at EPCOR and Chair of WEF’s Waterborne Infectious Disease Outbreak Control Subcommittee (WIDOC) puts in plain terms what we know about dealing with coronavirus in the water sector. The key points: there is no evidence that coronavirus survives the disinfection processes for drinking water and wastewater treatment and no coronavirus-specific protections are recommended for employees involved in wastewater management. Read on for more.
Water Sector Request: ‘Flush Wisely’ (March 23)
As the world adapts to dealing with coronavirus — social distancing, working from home, and self-quarantining if ill — the perceived hoarding and scarcity of toilet paper has emerged almost as a joke. But, if people start flushing unsuitable materials, the results will be anything but funny.
Webcast: Clean Water Act Regulatory Issues in a Pandemic (March 20)
During the coronavirus pandemic, water and wastewater utilities are currently triggering their response plans for continuity of operations. These events also trigger regulatory issues under the Clean Water Act as utilities work to maintain compliance during this pandemic. Utilities need to consider special conditions in their Consent Decrees and/or permits, consider regulatory obligations and maintain close contact with their regulators. This webcast will provide information on key considerations from a regulator and a regulated community perspective.
Webcast: Pandemic Continuity of Operations (COOP) Essential Personnel (March 19)
During the coronavirus pandemic, water and wastewater utilities are currently triggering their response plans for continuity of operations. A significant component during a pandemic is a consideration of critical functions that include essential personnel whose role does not allow for telework. Critical services must continue and COOP activities in the face of potentially severe staff shortages and absenteeism are of concern. This webcast will focus on the role of essential personnel.
