Not Just “Porta Potties” Anymore


We here at On Site understand how most people feel about “porta potties”.  Some people have had some bad experiences with them in the past, but we are here to let you know that there is so much more to the  sanitation industry than just “porta potties”.

Porta Potties

Yes portable restrooms, or “porta potties” as they are called sometimes, are still the primary staple of our industry, but things have been changing in the world of providing sanitation to the masses. The industry as a whole has set standards for how many restrooms should be used, and steps have been taken with sanitation organizations to ensure that vendors are fully prepared to provide clean portable restrooms. The sanitation industry has also been innovating with  hand wash stations, flushable portable units and even mobile restroom trailers.

Portable Sanitation Innovation

I’m sure that all of you have used a portable restroom at least one time in your life,  you know that it is not exactly the same as using a regular stationary restroom. Over the years On Site, as well as the majority of the sanitation industry, has been working tirelessly to find new ways to make the experience more parallel to a stationary restroom experience. One of the first steps that had to be made was to ensure that every event or location has enough restrooms provided for the number of people that will be using them. The Portable Sanitation Association International (PSAI) set a standard of One Restroom per 100 people that will be attending an event. The length of the event, and how long people are expected to stay will also determine the number of portable restrooms required. By ordering the correct number of portable restrooms for an event, party organizers and community planners will be providing patrons with a clean sanitation solution that I am pretty sure everyone can appreciate.

Clean Hands Initiative

Great innovations have also been made in the products that the portable sanitation industry provides. Back in the day, the only option that you had was the traditional “porta potty” for any special event or party.  Through the years the industry has started providing hand sanitizer to keep you a little cleaner. Hand sanitizer was a great first step in keeping patrons clean, and now we have taken it a step further with portable hand washing stations. These stations have clean water and hand soap for a more traditional hand washing experience. They also provide paper towels to dry your hands.

A Little Bit Closer to a “Normal” Bathroom

Clean hands are not where we stopped in our innovation pathway. A while ago, Satellite Industries invented the portable flushing restroom. This restroom looks mostly the same as a typical “porta potty” but provides users with a little something extra. A flushing mechanism and a foot pump hand sink has enabled this restroom to provide something a little bit closer to home anywhere you need it.

The Trailers Have Arrived!

The last stop on our evolution of portable restrooms is the luxury restroom trailer. I’m sure that you’ve seen these guys popping up at weddings and special events around town. These trailers vary in size and capacity, but they are usually sporting flush toilets and running water hand sinks. Some of the more upscale versions even have heating, air conditioning and wood flooring. This has brought the portable sanitation industry pretty close to stationary restrooms. These bathrooms are almost indistinguishable from a normal bathroom, and in some cases they are even nicer than some of the bathrooms you may have used in the past.

It’s Always Getting Better

Although the sanitation industry may not have the best reputation with some people, we are always striving to improve the services that we provide. We take pride in the steps that we have taken to get your “porta potty” experience to more traditional restrooms, and we are not going to stop trying to improve our offerings. If you are interested in some of the products that we have talked about, feel free to contact us for more information. Be sure to keep these products in mind for the next party or special event that you are planning, and maybe even request more amenities for events that you attend. I’m sure the event organizers want to provide you with a great experience as well!
