How many portable toilets do I need?
OSHA 1926.51(c)(1) requires 1 toilet facility for 20 workers or fewer on a construction site; from 20 to 200 workers you need 1 toilet seat and 1 urinal per 40 workers. At 200 or more workers, the ratio is 1 toilet seat and 1 urinal per 50 workers. For events in Chattanooga, the count depends on expected attendance and event duration. A wedding with 150 guests needs fewer units than a three-day music festival with 500 people per day. How many porta potties do I need covers the math in detail. Call us with your headcount and we'll spec the right number.
What's the difference between standard and deluxe units?
A standard porta potty holds 60 to 70 gallons and measures about 44 by 48 inches on the ground, standing 92 inches tall. It has a simple chemical toilet, hand sanitizer and a toilet paper dispenser. A deluxe flushable porta potty adds a flushing mechanism, better ventilation, soap dispensers and a more finished interior. Both work for Chattanooga construction sites and events. Deluxe units cost more but feel closer to a real bathroom. ADA accessible units meet ADA Standards section 213.2: one accessible unit per five units in a cluster, never fewer than one. Choose based on your budget and how long people will use each unit.
When do I need a restroom trailer instead of portable toilets?
A restroom trailer makes sense for jobs lasting weeks or months, or events where hundreds of people need facilities. A 2-stall trailer suits small crews. A 4-stall works for medium events. An 8-stall restroom trailer handles large festivals and construction sites in Chattanooga. Trailers include running water, flushing toilets, sinks, mirrors and climate control. A shower trailer adds hot water showers for farm workers, disaster relief crews or outdoor events. Trailers cost more upfront but deliver better comfort and less frequent servicing than portable units scattered around a site.
What about septic pumping and grease traps?
A residential septic tank is typically pumped every 3 to 5 years, driven by tank size and household size. Septic tank warning signs include slow drains, odors and wet patches in the yard. Commercial kitchens need grease trap pumping when fats, oils, grease and solids reach 25 percent of the liquid depth. Chattanooga Porta Pros handles both. We also rent holding tanks for temporary jobs. Emergency septic service is available if your tank backs up on a weekend.
How do I know what size dumpster I need?
Match the dumpster to the job scope and weight of debris. A 10 yard dumpster suits small renovations and cleanouts. A 20 yard dumpster fits most construction jobs. A 30 yard or 40 yard dumpster handles major demolition and land clearing. Dumpster weight limits apply; heavy soil, concrete and metal count more than drywall. A roll-off delivery needs about 60 feet of straight clearance behind the truck. See dumpster sizes and dimensions for exact specs. We deliver and pick up; placement near Chattanooga streets may need city approval.
What can't go in a dumpster?
What cannot go in a dumpster lists paint, batteries, electronics, tires, hazardous chemicals and asbestos. OSHA 1926.252 covers disposal of waste materials. These items need special handling or separate disposal. Tell us what you're throwing away and we'll advise.
Do I need handwashing stations on a construction site?
Yes. OSHA 1926.51(f)(1) requires washing facilities where employees apply paints, coatings, herbicides or insecticides. 29 CFR 1910.141(d)(2) says washing facilities must have soap and towels or a hand drying device; hand sanitizer alone does not meet code. A portable handwashing station or portable sink keeps your crew compliant. Chattanooga Porta Pros delivers them with hot and cold water options.
How fast can you deliver?
Most Chattanooga jobs get delivery within 24 hours. We confirm placement details and access before arrival. Call contact for same-day or next-morning availability.
Do porta potties really smell bad?
A well-serviced unit smells far less than you'd expect. We visit weekly under ANSI/PSAI Z4.3 baseline service for up to 10 users over a 40 hour week. Regular pumping, deodorizer and ventilation keep odors minimal. Do porta potties smell explains the science.
Can I rent equipment for just a weekend?
Yes. Weekend rates apply to Friday pickup through Sunday return. Pricing is higher per day than weekly or monthly but works for events and short jobs. Call for a weekend quote.
