Facts about Portable Toilets



They have many names, port-a-potty, porta potty, portable john, portable potties, portable sanitation units, restroom trailers, and the water closet. Either way you label them; portable toilets have been around for quite some time as a convenience for personal and business events. If you have any questions about portable toilets, here are a few answers.

When was the first portable toilet invented?

In the 1940’s, shipyard crewmembers needed a convenient method of using the restroom. It was a huge cost, as the laborers had to go back and forth from the ship to the dock to use the restroom. So, one of the managers had designed a wood cabana and holding tank placed on the dock, and the portable toilet began. George Harding did not patent it until 1962. PolyJohn Corporation and the age of portable toilets began thanks to cofounders George Harding, George Hiskes, and Ed Cooper.

How do you keep the smell down in a portable toilet?

Portable toilet systems are more than meets the eye. Depending on the length of use, you can have an entire Interior Restroom System consisting of a 100-gallon fresh water-holding tank and a 250 gallon secured waste container. This is an Odorless external system. The waste tank fits under the trailer.

A standard porta-potty has a 62-gallon wastewater-holding tank and plenty of ventilation. Many times, the company will use a combination of fragrance and a dark blue dye to mask the odor between cycling out the waste tanks.

How sanitary are portable toilets?

Portable toilets are now just as sanitary as a restaurant or hotel’s restroom. Some restroom trailers provide baby-changing stations. They have no toilets inside the room and are made of FDA-approved polyethylene, which resists bacterial growth. You will find a variety of toilets such as ADA complaint Wheelchair Accessible Restrooms and Luxury Restroom Trailers.

You’ll also find at events that valet services are available to ensure the restrooms are clean and well stocked with supplies. There are also plenty of other accessories to keep you clean such as hand sanitizers, Hand Wipes & Foam, Quad Wash Station, and Portable Sink with running hot and cold water.

Why would I rent a portable toilet rather than use the one at my business or at the park?

Portable toilets offer the convenience of no maintenance. You don’t worry about your sewer clogging. You have a dependable restroom system to use for any event. It’s a perfect way to ensure you have enough stalls for guests. Finally, some are transferable for mobile sites.

Porta Potty Rental – Tips for Event Planning

Winter can be the time of the year where it is OK to be a hermit where there are very little outdoor events. Summer means getting out and seeing friends and family. It is the time for good food, music, and conversation. Planning the event can take time and lot of work so we havetips-for-event-planning put together a great list of tips for event planning.

We have all been to parties where the food was horrible or had to wait in long lines for the porta potty. For those who love event planning, you want everything to be spectacular. You want your guests to be happy, comfortable, and enjoy themselves. There are many hats to be worn as an event planner. You must make sure to cover all necessities so here is a great list of tips for event planning that can help even the most experienced event planner.

Tips for Event Planning

Plan for the Number of Attendees

Try to get as accurate as possible of a head count of those expecting to attend. If you are unsure, it is better to plan for how many people were invited plus one. Therefore, if you believe 50 people know of the event, plan for 100, especially if this is a mixer of some sort where many people do not know each other.

Organize For Food, Drinks, and Entertainment

After you’ve finalized an accurate head count, it’s time for the meat of the party. You want enough food and drinks to be passed along the entire time. Have a good blend of entertainment as well.

Make the Environment Comfortable

If your party is lasting more than 3 hours, have children expected to attend, or you have liquor, plan for restroom services. An excellent and professional porta potty rental company is a sure way to bring comfort to any event. As mentioned, you never know how many attendees you may have and you want them to have a clean and sanitized area for them without a long wait.

Why the portable restroom is pivotal to society

The portable restroom rental has been a staple in U.S. society for decades and has even picked up a few nicknames along the way.  All toilet humor aside, the portable restroom industry is not something to be scoffed at. The porta potty, whether it is a standard portable toilet or luxury restroom trailer rental, is pivotal to society in a number of ways.

Why portable restrooms are important in society.

1. Prevention in spreading disease

In reducing the proliferation of bacteria and disease, it is pivotal to maintain public hygiene. Hand contact is the fastest way bacteria and diseases are spread from person to person.

Hand sanitizing facilities are used in more than just public or portable restroom rentals.  One common need is in hospitals, where Hand Sanitizer is frequently available for use to prevent the spread of germs and viruses.

We also provide cleanliness outdoors with convenient hand sanitation.  If you’re an artist conducting an outdoor workshop, a Portable Sink is a handy way to wash up after a creative day of painting.  Events, such as parties, could also use hand washing stations due to the lack of running water we often find outdoors.  Your attendees overall experience can be heavily influenced by their restroom and hand washing experience.

Also, Hand Wipes and Foam will always get the food off of your fingers, as well as keep childrens’ hands clean without the excessive use of soap and water.

Catering services and food vendors typically require separate facilities – we’ve got you covered.  Don’s Johns provides a Dual Wash Station for a small team of event caterers, as well as a Quad Wash Station that can serve an entire crew at once!

Portable sinks provide a separate water supply that allow you to wash your hands to keep them clean after being exposed to bacteria infested areas or using a portable toilet without its own hand washing station.  For simultaneous hand washing needs, Dual and Quad wash stations are also available to allow multiple workers or residents to take advantage of proper hand sanitation.

Don’s Johns has cleanliness covered when it comes to public sanitation.  Some of our restrooms, including the VIP Flushing Toilet w/ Sink and the Premier Flushing Porcelain Restroom have sinks built in directly for your convenience.

When water isn’t available for hand washing purposes, or when portable restrooms aren’t provided with sinks of their own, it is important to consider Hand sanitizers, hand wipes and foam. The use of waterless hand sanitizers, wipes or foam kills 99.9% of the most common illness-causing germs.

For complete Hygiene Maintenance, Shower Trailers can bring the comfort of complete cleanliness during a time where such facilities are unavailable for extended periods.  Shower trailers come available with both Men’s and Women’s sides; each with three shower stalls, one toilet, and one sink. All shower stalls also feature attached dressing areas with fold-down seating and non-skid floors.

2. Convenience and comfort for the outdoors

Restroom Trailers and portable toilets are the perfect answer to the question of how to achieve maximum restroom-trailercomfort and convenience in the great outdoors.  Whether you only want an economical restroom trailer with 2 separate stalls or a Restroom Trailer that was actually voted one of America’s Best Restrooms in 2011, there is a selection for everyone! There is also a perfect solution for outdoor needs catering to crowds of any size.  We have set up everything from a single porta potty to over 5,000 portable restroom rental units for a single event.  No matter what the size, scope or location of your outdoor restroom needs, Don’s Johns will always have what you need, when you need it!

3. Efficiency in the workplace

Oftentimes, projects are in need of at least one portable restroom rental.  Whether it’s a single home bathroom renovation that needs one portable toilet or a multi-story development project covering an area over 1 million square feet, there is the perfect portable toilet solution for you.

Construction projects can use interior restroom systems for office trailers, clusters of portable restroom units for workers on site, hi-rise portable toilets for multi-story projects, and even rolloway portable toilets for use when moving from one area of the work site to another. For projects that are on the move, Don’s Johns offers a mobile portable toilet, fully equipped with a trailer.  Just hook it up to your vehicle and you’re ready to roll for a long distance transportation project or even a road crew working on sections of a highway.

4. Emergency Response

Unfortunately, disasters happen more frequently than any of us would like them to.  However, there are specific precautionary measures Emergency Responders can have in place in case a disaster happens in your area.

Hurricanes, wildfires, biohazard accidents, earthquakes, floods and landslides can happen in the blink of an eye and once a disaster happens, the importance of sanitation instantly becomes paramount in preventing illness and death to residents and workers in the affected area.  Just because an emergency occurs does not mean that Mother Nature stops taking its course. The need to get rid of human waste and maintain proper sanitation standards will inevitably continue. Bacteria can flourish and diseases such as typhoid, dysentery and Giardia can severely impact innocent victims of a natural or man made disaster due to the lack of personal hygiene and waste disposal.  Being properly prepared and implementing the following provisions to handle these situations will reduce the risk of further contamination once an emergency has occurred.

Elimination of Waste –

Having portable restrooms are vital to maintaining proper sanitation and eliminating the need for waste disposal in an affected area.

One thing that remains consistent during these times of trouble is the 24/7 ability of Don’s Johns to provide the right Emergency Services for those in need of a portable toilet rental or restroom trailer. Shower trailer rentals are also used often to maintain hygiene in an affected area.  Even hand sanitizer and hand washing stations are often found within temporary medical facilities. Emergency preparedness is in the hands of our local, state and federal Emergency management agencies, but every individual effort helps.  A few things you can do to take a pro-active approach to managing an Emergency are

You can also purchase a used porta john for sale.  Buying Portable Toilets for your locale during an emergency is a lot more realistic than you may think.  You can purchase a used porta john for sale at a reasonable price, and have your own portable restroom available for the health, safety and comfort of you and your neighborhood.

Portable Restroom Rental in Virginia

The news about portable toilets and Don’s Johns in the portable restroom rental industry made big headlines with a groundbreaking story at Arlington National Cemetery in 1968. The Day reported on April 20th that a retired Colonel wanted to have portable toilets that were placed near the cemetery moved to a new location, out of public view. These early Don’s Johns porta potty units were placed on location for an unstated reason, although they may have been there to serve the public visiting family and loved ones at the National Cemetery, the paper said.

Portable Toilets: Reflecting on Foundations

The Lakeland Ledger reported a story in 1974 about Don Rainwater and how he got started in the portable restroom rental industry. “Needa John? Call Don!” was the original slogan on the founders’ business card, featuring a cartoon of himself on the back of the card, sitting on a toilet. Rainwater got the idea to get into the portable toilet business when he loaned money to a friend to get into the porta potty practice. According to Don, it “Sounded like a good idea, so I decided to do it too. Started with 12 wooden shacks with 55 gallon buckets in ‘em”. Don also invented the “Speedy-Vac” pumping system that used about 1/4th of the needed gasoline as compared to the other pumps at the time. Before becoming a porta potty professional, Don had created many inventions, was in the construction industry, the lumber business with his brother, a restaurant, and finally, Don’s Johns Portable Restroom Rentals and Sanitation Services.

Portable Toilets for Presidential Inaugurations

In 1997, the Washington Post reported that Don’s Johns co-founder and owner, Thelma Rainwater, along with granddaughter Kristie Dunston Harrell had secured the Inaugural contract with the co-executive director of the inaugural committee. According to the article, 816 portable restroom rental units were used for the approximate 300,000 in attendance.

The Washington Post also reported in 2008 that Don’s Johns was serving the Obama Presidential Inauguration to create what is still known today as the largest portable restroom rental event in the history of the United States. Approximately 7,800 portable toilets were rented between multiple portable restroom rental companies to serve the 2,000,000 people expected in attendance.
