3 Key Things to Know About Porta Potty Rental

When you need a porta potty rental, you’ll need to know a few things to make the rental process go smoothly. Because it’s a large and well-established industry, securing a rental is a straightforward process when you work with the right company. In fact, experienced porta potty professionals will streamline the rental process so you can have peace of mind when it’s time to use them for your event or site. Let’s take a closer look at just three key aspects of renting high-quality porta potties below.

1. There’s a Wide Range of Unit Types

Many people think of the outdoor restrooms that are commonly spotted on construction sites when they think of porta potty rental services, but this is just the beginning! There’s a wide range of unit types available. From basic units to ADA-compliant models, if you need a particular type of outdoor toilet, your local rental company likely has it. Units for construction sites and other work areas don’t need all the bells and whistles that an outdoor garden party or symphony performance would require. Fortunately, there’s a lot in between the bare-bones model and the ultra-deluxe luxury model. If you want an ADA-accessible unit with lighting, a sink, and a fan or ventilation, that’s also possible. Your rental company should have a coordinator or other customer support staff to help you with your rental order details and specifications.

One of the most popular options for outdoor weddings and events is the outdoor comfort stations. These trailers have everything from subtle lighting to full toilets and sinks. Outdoor events can now maintain an atmosphere of sophistication while still providing guests with the comfort services they need.

2. On Site Can Help Ensure You Have the Correct Number of Porta Potties

The right porta potty rental company will help ensure you have the correct number of porta potties based on how many people will need to utilize them. When you call to book your rental, you’ll need to know how many units you’ll need or how many people will be attending, what type, the timespan, if there will be alcohol, and how often they’ll need to be emptied.

If you’re unsure about any of these details, the rental company will be able to walk you through the process and help you determine what type of equipment will best meet your rental needs. Don’t be shy about asking questions or for clarification during the rental process. There’s more to a porta potty rental than many people realize!

3. Emptying and Removal Should Be Included in Your Contract

Once you’ve found a reliable company for your rental, you’ll want to get down to the details. You’ll need to know the cost of the rental, any fees for extended rental periods, and details related to the removal of the waste as well as delivery. All of these points should be clearly explained in the contract. You’ll want to fully review the terms of the rental and pay careful attention to the waste removal clause. When you file for your permit, there could be specifications about how long the portable toilets can be in place and how often they have to be emptied. Be sure that your contract conforms with any municipal requirements. No one wants to have to deal with expensive fines because they didn’t read and understand all the relevant information.

Once you’ve fully reviewed your contract and confirmed that everything is in alignment with municipal requirements, you’ll want to confirm a few other details. Make sure that the delivery and pick-up dates are correct, confirm your billing information, and be sure you’re in clear agreement with all the terms of the rental agreement contract. If you’re unsure about how many units you’ll need for your event, your rental company should be able to provide guidance once you let them know the nature of the event and the number of participants. When in doubt, it’s better to have too many units than too few!

On Site Companies is the company to call for all your porta potty rental needs. We can help you with everything from basic units for a fun run to luxury comfort stations perfect for the most elegant events. Contact us today to learn more about our products and services. We look forward to hearing from you soon!

ANSI Portable Restroom Standards

One of the most basic urgencies of the human body is the need to relieve oneself through urination or a bowel movement. When this happens, and you are not at home, you need access to some type of facility in order to take care of business. Portable restrooms are often the option available for this purpose, especially in outdoor settings. OSHA mandates certain requirements related to portable restrooms and their use. The ANSI standard offers even more strict guidelines. We look at some of these below. At On Site Companies, we are your source for a variety of portable restroom options to accommodate the needs of your guests, employees, or other persons.

OSHA Requirements

OSHA 29 CFR 1926.51 specifies the minimum number of lavatories to be present on a site based on the number of workers at the site. For example, only one portable restroom is required if 20 or fewer workers are onsite. When 20 or more workers are onsite, employees must have access to 1 urinal and 1 toilet seat for every 40 workers. When over 200 workers are present, the manager of the site must provide 1 urinal and 1 toilet set for every 50 workers.

ANSI Standards

The OSHA standard must be followed in the United States. The ANSI standards offer more stringent guidelines. For example, ANSI/PSAI Z4.3-2016 – Sanitation – Nonsewered Waste-Disposal Systems provide a minimum requirement of 1 toilet facility per 10 employees. This changes to 1 toilet facility per 15 employees if the facilities are serviced more than one time per week. In addition, these numbers apply to each gender. So there would have to be 1 toilet per 10 males and 1 toilet per 10 females.

The ANSI/PSAI Z4.3-2016 standard does not specify the type of facility to be used. It allows for the use of plastic portable restrooms or mobile trailers or skid-mounted or prefabricated, portable structures, as long as they include self-closing doors, sufficient space inside, and a finish which is easy to clean. Also, if it is not feasible to find a portable toilet room, and if adequate privacy is provided, portable toilet facilities may be installed without a structure.

Even though the ANSI/PSAI Z4.3-2016 standard was originally created for construction sites, later versions of the standard provide more in-depth guidelines for other venues such as playground and parks. By adhering the ANSI standard for portable restrooms, one can help ensure their successful and safe application at a particular site.

Common Myths About Portable Restrooms Debunked

Many ideas you may or may not have been told about portable restrooms are not necessarily factual. There are a number of misconceptions about these pieces of equipment that ought to be cleared up. At On Site Companies, we offer an array of portable restroom solutions designed for many types of outdoor settings and events so today we would like to address some of these ideas.

Myth #1: Portable Restrooms Will Look Bad at a Formal or Upscale Event

Portable luxury restroom trailers provide amenities that go beyond those of the typical, standard portable restroom. These may include air conditioning and heating, faux wood flooring, Formica marbled sinks or countertops, oak cabinets, and more. Some of them feature multiple stalls to handle multiple persons at a time.

Myth #2: Portable Restrooms are Unsanitary and Smelly

A big misconception is that all portable restrooms are unsanitary. While some mobile bathrooms of the past may have fallen into this category much of the time, our new portable restrooms, including luxury portable units, are designed with quality and user experience in mind including features such as: running water, sanitizers or soap dispensers, flushable toilets, easy-to-clean surfaces, and vents to control odors.

Myth #3: You Can’t Wash Your Hands in a Portable Restroom

Another misconception is that portable bathrooms lack any accessory for washing the hands. However, that is largely false. All standard units include hand sanitizers at a minimum. Other luxury models feature running water sinks. In other cases, portable hand washing units are placed outside of bathrooms that can be used.

Myth #4: Portable Restrooms Are Only for Festivals and Construction Sites

Another myth is that portable restrooms are only applicable for large outdoor festivals or construction sites, not small events. However, they are actually ideal for personal use events such as weddings, graduation parties, and family reunions. In addition, some small, seasonal businesses rent portable restrooms for parks, farms, and golf courses.

Myth #5: Portable Restrooms are Bad for the Environment

Standard portable restrooms don’t require water after use. Running water toilets can waste up to a couple hundred gallons of water daily. Portable restrooms save tens of billions of water every year. This is significant since toilet flushing is the highest use of water in the United States.

Key Environmental Benefits of Portable Restrooms

At One Site Companies, we provide only the most experienced knowledge and sources for portable sanitation systems. Portable restrooms offer several benefits on top of providing a safe, sanitized, and easy to use private environment for users.

In our mission, we would like to provide insight for you on how portable restrooms also have huge environmental benefits for users.

Conserving Water

Flushing is the largest daily use of water in the United States, including showering and hand washing. Portable restrooms conserve water since they don’t require flushing after every use. According to the PSAI 45 billion gallons of fresh water are saved annually by portable restroom use.

Protecting Landscaping and Waterways

Portable restrooms help preserve the surrounding landscaping by saving plant life from harm due to individual waste on bushes and trees. They also prevent human waste from reaching streams where it can poison certain bodies of water, harming local flora and wildlife. Portable restrooms keep human waste safely contained until it is disposed of for treatment, protecting the surrounding natural environment.

Reduced Insect Problems

Containing human waste in portable restrooms helps prevent the problem of insects swarming to the waste. If a person’s waste contains any parasites, they could end up in the soil when not properly contained in a portable restroom. This could potentially infect someone else who came into contact with the waste and cause damage to the environment.

Preserving Public Health

Various diseases spread through the transfer of fecal matter to the mouth. When someone does a bowel movement, but fails to wash their hands properly, and then touches objects such as utensils or food, the germs can spread and cause sickness. The same is true for urinating without washing the hands. Portable restrooms with hand sanitizer or soap dispensers and running water solve this problem. Otherwise, individuals at various outdoor events are forced to go to the bathroom in the bushes somewhere without an opportunity to sanitize themselves, including their hands.

Odor Control

The design of portable restrooms today includes better odor control than older generation porta potties. Here at On Site Companies, we use hospital-grade disinfectant to clean our units and take great measures to ensure a pleasant experience. This means that regardless of whether or not it is the type of mobile restroom that flushes, it will not spread an unappealing aroma to areas of your area, even if you have multiple portable restrooms set up throughout your venue.
