Outdoor gatherings can be tricky to plan. From Deep Ellum outdoor festivals to Denton County fairs, what your attendees will care most about is efficiency. If they have to wait half an hour in line just to wash their hands, they won’t be in a position to appreciate your programming. Take comfort into consideration — understand Dallas’ temperature averages and all the other possible event variables. Let’s look at every angle.
Assessing Capacity First
You should know roughly how many people are coming to your event. Rules of thumb don’t matter when thousands of guests descend on your festival — having enough units to meet basic human needs is essential.
Think about your minimum requirements first. If your event is four hours, plan on one porta-potty for every 75 attendees, and increase that number as your crowd size increases.
Rather than having the line for your outdoor event portable toilets wrap around your venue twice, it’s smart to overestimate. As you get closer to expecting 1,000 people, find and work with a specialist who can project demand at different times of your event.
- You always want to have a couple of units open and unused. Nobody wants to wait in line during intermission.
- Locate them near concession areas, but not too close for comfort.
- Designate an accessible route for your porta-potty service to reach them in case your event is multi-day.
How Many Porta-Potties Per Person Are Required in Dallas?
Every event is different. Crowd demographics play a big part in usage calculations: A marathon has predictable surges at the finish line. A family reunion at a Dallas Park does not. Also, consider the gender breakdown of your attendees. Women typically spend more time inside a restroom, and will need more women’s units to account for the longer wait times.
Parents with small children will likely need ADA Portable toilets, too. Did you know that under the Americans with Disabilities Act, you’re required to supply ADA-compliant toilets? Larger and more comfortable than traditional portable toilets for events, these units provide enough room for guests with strollers and wheelchairs. You’ll need to be sure that at least 10% of your fleet is ADA accessible.
Event Type Matters When Renting Porta Potties
Weddings and outdoor concerts have different guest expectations, too. Trade shows and weddings generally require upgraded amenities and a mirror. Consider how many luxe porta-potties per person you’ll need based on the type of event you’re planning.
If alcohol is being served, add 20% more units overall. With summer quickly approaching in Texas, hydration is key. So while your guests are consuming endless cups of ice water, they will also be visiting your rented porta-potties more frequently. Too many events under-provision their units in the hope that guests can “hold it” until the rush is over. That’s not how it works.
Time of Day and Event Length Directly Correlate
Every hour matters. A one-day special event needs less capacity than a weekend wedding. But when calculating how many portable toilets you need, multiply by the number of event hours. All portable toilets for rent have a limited number of uses before they need to be pumped.
Say your event is eight hours. The unit’s usage per person will be doubled from someone at a two-hour workshop. For events extending overnight into North Texas, you also have to factor in cleaning services. How often the portable toilets for events are pumped will determine how many you actually need.
Breaking It Down
- Figure out your baseline for a four-hour event.
- Add one additional portable toilet per 100 guests for every two hours beyond four.
- If your event is over 12 hours, you’ll need a professional pump service to clean them midway.
How Your Site Impacts Your Porta Potty Order Quantity
Flat landscapes don’t typically exist in Texas. The terrain of your outdoor event can drastically change how many portable toilets you need to rent. Spreading your units out over a wide area means guests won’t have to travel across the property to access them. Increase your order if your venue is more than half an acre.
Visibility can be another concern. You don’t want your guests trying to find the portable toilets for your event by combing through bushes, while you also shouldn’t have to look through your list of attractions to spot them. Try to position them backstage, or use temporary fencing to separate them from your main event.
Dallas Weather Influences How Many Portable Toilets You Need
Whatever season your project takes place in, you should plan for inclement weather. Portable toilets for rent don’t stand very well in Dallas wind. If you aren’t using them in a covered patio space, plan on having them secured. Larger events with dozens of porta-potties should consider trailer-mounted options.
