Pro Monthly Magazine

“I can say I’ve never appreciated a portable restroom as much as I did this weekend. Not only the availability of the units at each of our stops when we exchanged runners, but also the awesome service provided by a local restroom operator.” – http://www.promonthly.com/blog/2014/08/i_will_run_200_hundred_miles

Basilica Block Party

“Thank you for helping with the 2008 Cities 97 Basilica Block Party! Once again it was exciting to celebrate this summer tradition with great music, good food and lots of fun. I want you to know how much I appreciate your leadership in this year’s Party of a Higher Order with portable toilets. I am very grateful to everyone who helped to make our fourteenth annual block party an overwhelming success.

Thank you again from this year’s Basilica Block Party. Please know of our parish’s as well as my personal gratitude for your role with On Site Sanitation. With your help, we continue to spread the wonderful spirit of the Basilica of Saint Mary throughout our great city.” -7/18/2008

Uptown Association

The Uptown Association has proudly contracted with On Site Sanitation for over 10 years and counting. They continue to provide excellent rental support for the Uptown Art Fair in the areas of portable restrooms, sinks, and cardboard receptacles. The Uptown Art Fair, now in its 49th year, is a complex event with high expectations. Our festival averages 375,000 attendees, but On Site seamlessly meets our needs in spite of the challenges associated with navigating such a large event. Furthermore, their staff is prompt, accessible, reliable, and a pleasure to work with. I can confidently recommend On Site Sanitation as a solid and reliable vendor, and expert in their field.
