Convention and Trade Show

The PSAI’s Annual Convention and Trade Show is the world’s largest event of its kind focused solely on the portable sanitation industry. Attendees can count on hands-on learning opportunities, access to great speakers and networking, the chance to see the latest equipment, and enough fun to fill a pump truck. Whether you are a portable restroom veteran, just opened your business – or you’re somewhere in between – the PSAI’s Annual Convention and Trade Show has something for you.

  • The 51st Annual Convention and Trade Show will be held at the Baltimore Convention Center, Baltimore Maryland. We’ll announce the full program in the fall of 2019 via our weekly newsletter, Association Insight.
  • We have secured a special rate of $229 at the Baltimore Hilton hotel; it’s conveniently connected to the Convention Center. The Hilton is also a 2-minute walk from Oriole Park at Camden Yards baseball stadium, and a mile from the National Aquarium. Please make your reservations beginning in October 2019. Remember, when you stay at the Convention hotel, you not only have the most convenient option for participating in the event, you help us keep attendance costs down.
