You’re Invited to AC20 Virtual Conference & Expo

Conference Theme – This Is Why

No doubt this has been a challenging year for many of us, especially those serving in new roles as essential workers. CWEA members typically spend time together at conferences and events talking about what we do as wastewater professionals and how we do it—and there will be plenty of that at AC20 in our new virtual conference format. This year, with This Is Why, we want to give some thought to why we do what we do.

Pacific Ocean coast, California, USA

People in wastewater are among the smartest, most motivated, most capable people in the world. Our conference theme this year, This Is Why, is our way of reminding us to think about why we work so hard, and to celebrate your successes. Just think of all the ways water is used in California. Without you, none of that is possible.

Technical Sessions and Featured Tracks

We hope to see more members than ever on our new virtual conference platform. The Program Team has assembled a wide range of technical sessions and training that will cover collection systems, operations and maintenance, advanced treatment technologies, engineering and research, laboratory, State regulations and more.

Thank you to our expert speakers for leading conversations online with AC20 attendees and sharing your knowledge and experience with peers. The majority of presentations this year are “Curated Tracks,” tailored to cover hot-button issues within the sector. Be sure to check them out for deep dives into critical current topics. Session content will be recorded for future access, and depending on the registration option you’ve selected, you can have access to all on-demand content for up to 90 days after the event. The online conference training will be more accessible than ever without the added cost or burdens of traveling.

AC20 Virtual Expo

CWEA’s dynamic virtual conference platform provides a fully interactive expo hall, featuring exhibitors from across California. We’ve included plentiful opportunities for exhibitor and sponsorship networking, all while attendees connect from the comfort and safety of their home or office.

Networking Opportunities

One of the cornerstones of CWEA’s Annual Conference is networking, allowing attendees to get together to see old friends and make new ones. While we will be unable to gather in person for the foreseeable future, we’re designing AC20 to capitalize on the best of what online delivery affords and building numerous opportunities to safely participate in meaningful collaboration with colleagues near and far.

Join us on the AC virtual platform for:

See You Online!

It’s going to be an amazing, first of its kind conference. Join 1,000 or more wastewater professionals to help celebrate This Is Why! We hope you can also benefit from the new conference format. Get registered today.

Special thanks to all the volunteers and staff contributing to make this event and online format an amazing success.

What is CWEA doing in light of the novel coronavirus (COVID-19)?

This is a rapidly evolving situation and we understand you may have questions about the CWEA Annual Conference. The CWEA Board and staff places the health and safety of our members, attendees and staff as our first priority.

The CDC notes the risk of being exposed to COVID-19 is thought to be low. Link to CDC guidance.

Based on current federal and state guidance, Annual Conference is a go.

The CWEA Board and Staff are monitoring and reviewing daily updates from federal, state and local health officials. As information changes, we’ll take any additional necessary steps to ensure the health and safety of all attendees.

What steps are the Reno-Sparks Convention Center taking?

Please see this letter from Convention Center General Manager (pdf) >

What steps will be taken at Annual Conference?

Frequent hand washing and hand sanitizers are important.

We are implementing standard practices for events and conferences recommended by healthcare providers. We are following the guidance of the CDC, the American Society of Association Executives (ASAE) and others for instructions on how to properly manage the conference.

At AC20 you’ll see signs and hand sanitizing stations such as this.

We recommend following best practices for hand hygiene and cough/sneeze etiquette during the conference, and every day. Recommendations include:

  • Wash your hands frequently and for 20 seconds
  • Cover your mouth when coughing or sneezing or sneeze into your elbow
  • Please understand any attendee or exhibitor’s request not to shake hands
  • Stay away from someone who is coughing
  • Avoid touching your eyes, nose, and mouth with unwashed hands.

These hand sanitation practices also help prevent the spread of seasonal colds and flu.

What happens next?

The CWEA Board and Staff will continue to monitor daily instructions from the CDC, state and local health officials.

We’ll be frequently updating this Q&A with the latest information on an ongoing basis.

What about the safety of collection system and wastewater treatment professionals?

Wastewater worker safety information was assembled by WEF and is available on the CWEA E-Bulletin website or on the WEF website.
