WEF conferences are in-person educational and networking opportunities for all members of the water sector. These events are held at various locations throughout the world to share the best programming and information while gaining regional insights.



WEF’s priority in all meetings and events is the safety and welfare of our attendees, exhibitors, partners, and staff. To enable in-person events to take place with lower risk to participants, WEF is implementing the following health and well-being protocols.

These protocols were developed based on U.S. Centers for Disease Control and Prevention (CDC) guidance. WEF may adjust our health and well-being protocols as necessary.

  1. Show proof of full vaccination OR negative COVID-19 test

To attend in-person events, all participants must provide either proof of full vaccination* or proof of a negative COVID-19 test taken no more than 48-hours before arriving to pick up their badge or to register onsite.

Vaccination Record Options: participants can bring either a hard copy of their vaccination record or present a digital copy. Experts recommend taking a photograph of both sides of vaccination cards and keeping the photos on smartphones so they are accessible when needed. There are also some app-based options to show proof of vaccination, including Clear, which accepts CDC vaccination cards. Learn more.

Acceptable COVID-19 Tests: Rapid Antigen or Rapid Molecular (PCR) viral tests, including FDA-approved at-home/self-tests, are acceptable. Results must be verified by an official medical agency/clinic or telehealth service. Antibody tests are NOT acceptable.

  1. Masks

Masks are a critical public health tool that can reduce the spread of COVID-19. In areas where the COVID-19 Community Level is low or medium, current CDC guidance is that masks may not be needed indoors.   

WEF revised our masking protocols to align with the updated guidance from the CDC (March 2022). We are using COVID-19 Community Levels to determine masking protocols for WEF meetings and events based on the latest data. 

CDC COVID-19 Community Level Masking Guidance

WEF strongly encourages those who are immunocompromised and those who feel comfortable wearing a mask to do so. To find out what masking protocol is in place for a specific WEF meeting or event, please visit the event's website.  WEF will continue to monitor the COVID-19 Community Levels and adjust protocols as necessary.

WEF’s intention is to create a safe environment for all participants. Thank you for your understanding and cooperation. If you have questions or concerns about WEF's Event Health and Well-being Protocols, contact [email protected].


*The CDC defines fully vaccinated as:

  • 2 weeks after the second dose in a 2-dose series, such as the Pfizer or Moderna vaccines, or
  • 2 weeks after a single-dose vaccine, such as Johnson & Johnson’s Janssen vaccine.

If you do not meet these requirements, you are NOT fully vaccinated. WEF recommends that you follow CDC guidance and stay up-to-date with your vaccines.Learn More.
