How many portable toilets do I need?
OSHA 1926.51(c)(1) sets the baseline for construction work: one toilet seat per 20 workers or fewer, then one toilet seat and one urinal per 40 workers from 20 up. A crew of 60 needs at least three units. Events, weddings and festivals run different math because people use facilities less often and for shorter stretches. The porta potty sizing guide walks you through both scenarios. If you're not sure whether your site is construction or general use, send us photos and a headcount and we'll spec it for you. A single miscalculation upfront beats shutdowns and complaints mid-project.
What's the difference between a standard unit and a deluxe?
A standard porta potty is a single-occupant unit with a 60 to 70 gallon holding tank, manual flush and basic hand sanitizer. It's about 44 by 48 inches on the ground and stands 92 inches tall. A deluxe flushable model runs on 12-volt power or solar, has a real flush mechanism, a larger tank, running water, a sink and a mirror. Deluxe units cost more per day and per week. Construction sites in Aurora often run standard because crews need volume and cost matters. Weddings and corporate events pick deluxe because guests expect a real bathroom. Restroom trailers sit above both: they're multi-stall, climate-controlled, fully plumbed units with heat and air conditioning. Pick the one that fits your budget and your crowd.
What if I need an accessible unit?
The ADA accessible porta potty meets federal standards for door width, interior space and approach. ADA Standards section 213.2 require that when single-user portable toilet units are clustered, at least 5 percent must be accessible. Accessible units cost more than standard but they're legally required on any public event or any job site with workers who need them. Aurora has mixed terrain and weather, so placement matters. A ramp slope can't be steeper than 1:12 per ADA Standards section 405.2, and the ground has to be stable and firm. First Choice Porta Potty handles site surveys and placement at no extra charge. If your event or site needs to be ADA-compliant, we'll make sure it is.
When should I pump my septic tank?
A residential septic tank typically gets pumped every 3 to 5 years, driven by tank size and how many people live in the house. Commercial septic systems pump faster depending on daily flow. First Choice Porta Potty offers septic pumping service across Aurora. If you rent a holding tank for temporary work or an event, we schedule pickup and pumping on your timeline. A grease interceptor pumps when fats, oils, grease and solids reach 25 percent of the liquid depth. Don't wait for smell or backups. Call us to schedule grease trap pumping before the tank gets full.
Do handwashing stations count toward OSHA rules?
No. Handwashing is separate from toilet count. OSHA 1926.51(f)(1) requires washing facilities where employees are engaged in applying paints, coatings, herbicides or insecticides or other operations where harmful contaminants may be present. A handwashing station rental gives workers a place to wash their hands with real soap and towels or a hand dryer, as required by 29 CFR 1910.141(d)(2). Hand sanitizer does not satisfy either rule. Most construction sites in Aurora need both toilets and a handwashing station. First Choice Porta Potty delivers them together so you stay compliant.
