After careful consideration and evaluation, the Mega-Conference partners (NOWRA, VOWRA, NAWT, and SORA) decided to move the 2020 Onsite Wastewater Mega-Conference to an all-virtual format. This was a difficult decision, but it was driven by two critical factors: uncertainty surrounding our ability to hold this event safely, and uncertainty about whether the Commonwealth of Virginia would ease restrictions on the size of gatherings enough to enable our meeting to take place. Therefore, we will be moving to a virtual format for the entire conference.
