Highlights from the 2025 Onsite Wastewater Mega-Conference
Even if you missed out on attending this year’s Onsite Wastewater Mega-Conference in Ohio (like we did!), you haven’t missed out on the opportunity to learn from the conference proceedings! The National Onsite Wastewater Recycling Association (NOWRA), the lead organizer of the conference, has posted select papers and posters as well as most presentation slides for public access, as they do each year.
In this post, we list a selection of highlights that stand out to us, but we highly encourage you to check out the entire list of offerings available at the NOWRA website. Many of these links and documents will also be added to our Resources Library by the end of the year.
And when you’re done, be sure to mark your calendars for October 25-28, 2026: next year’s Onsite Wastewater Mega-Conference in Westminster, Colorado!
