ACE20 Update and Timeline
AWWA’s first core principle is the protection of public health. This principle informs our actions during normal times and especially during the COVID-19 crisis. It will continue to guide our decisions related to upcoming AWWA conferences and events.
We know many of you are waiting to hear if the AWWA Annual Conference and Exposition (ACE20), June 14-17 in Orlando, Fla., will proceed as planned. We know the uncertainty is difficult, and we thank you for your patience as we determine the best path forward.
AWWA will determine by Thursday, April 16 whether the conference will take place as scheduled on site or if circumstances require a change of plans. In making that decision, we are consulting with:
- Leading public health authorities, including the U.S. Centers for Disease Control (CDC), the World Health Organization (WHO), the U.S. Environmental Protection Agency (EPA) and Health Canada.
- Florida state and local public health authorities
- The Orange County Convention Center
- AWWA volunteer leaders and business partners
We will continue to communicate through regular AWWA e-mails as this situation develops, and please check back to this page for updates. We are also happy to talk with you by phone or email. Please call 1-800-926-7337 or email firstname.lastname@example.org.
Thank you for your patience during these difficult times, your participation in AWWA events, and most importantly, for your commitment to our common goal of protecting public health through safe and reliable water.

AWWA recommends postponing water shutoffs
Given the importance of hygiene and sanitation in mitigating the spread of COVID-19, AWWA recommends utilities postpone water shutoffs during the COVID-19 pandemic.
Note: AWWA’s Statement of Public Policy on the Discontinuance of Water Service for Nonpayment states that “certain circumstances may require some flexibility because water service is a necessity in maintaining sanitary conditions in the home, and may be required for life‐sustaining equipment, or for other critical purposes.” The current pandemic is such a time.
Notice on returning homes to service
When homes are returned to service after an extended period of discontinued service (e.g., weeks or months), an adult should be present in the home to ensure that the meter works, leaks are minimized, wastewater piping is intact, and the building’s plumbing is flushed. A thorough flushing process is appropriate in such situations.
Note: Social distancing protocols will need to be considered when engaging residents about customer assistance programs, managing lead, and other steps in returning service to the home.
Flushing instructions provided to occupants will vary depending on the structure. This is an area of active research. However, key elements of existing protocols include:
1. Remove or bypass devices like point-of-entry treatment units prior to flushing.
2. Take steps to prevent backflow or the siphoning of contaminants into plumbing (e.g., close valves separating irrigation systems from home plumbing, disconnect hoses attached to faucets, etc.)
3. Organize flushing to maximize the flow of water (e.g. opening all outlets simultaneously to flush the service line and then flushing outlets individually starting near where the water enters the structure).
4. Run enough water through all outlets (e.g., hose bibs, faucets, showerheads, toilets, etc.), removing aerators when possible. Typical durations in existing protocols range from 10 to 30 minutes for each outlet (duration varies based on outlet velocity).
5. Flush the cold water lines first, and then the hot water lines. Note: the hot water tank can be drained directly; it can require roughly 45 minutes to fully flush a typical 40-gallon hot water tank.
6. Replace all point-of-use filters, including the filter in refrigerators.
7. Additional precautions may be warranted if there is excessive disruption of pipe scale or if there are concerns about biofilm development. Actions that might be warranted include continued use of bottled water, installation of a point-of-use device, or engaging a contractor to thoroughly clean the plumbing system.
Residents should be reminded that if point-of-use devices are installed, POU devices should be properly installed and adequately maintained.
