Frequently Asked Questions in Casper, WY

OSHA 1926.51(c) sets the count by headcount. For 20 workers or fewer, you need 1 toilet facility. From 20 to 40 workers, add 1 toilet seat and 1 urinal. At 200 or more workers, the ratio is 1 toilet seat and 1 urinal per 50 employees. The math changes by site; a small renovation needs far less than a commercial build. Call Casper Porta Pros to walk through your crew size and schedule. We rent standard porta potties by the day, week, month or event, and can add ADA accessible units where the law requires them. A standard unit holds 60 to 70 gallons. If your project spans weeks, monthly rental saves money compared to daily rates. Read our guide on how many porta potties you need for the full breakdown.

Placement in the public right of way needs confirming with the city, and you'll want to verify permit rules before you order. A standard unit sits about 44 by 48 inches on the ground and stands 92 inches tall. Clear space matters for access and safety. Check with Casper municipal offices before committing to a spot on a street, sidewalk or public easement. We deliver and place units to your specifications, but the permit work is yours. Ask us during request a quote what we've seen approved in Casper recently; we've placed hundreds of units and know the common patterns.

Event restroom rental in Casper ranges from a single standard unit to luxury restroom trailers with flushing toilets, sinks and climate control. A standard unit works fine for 50 to 100 people over a few hours. For weddings, festivals or marathons, a restroom trailer holds more people and feels more dignified. Trailers rent by the day, weekend or event duration. We service units weekly under the baseline interval set by ANSI/PSAI Z4.3, and more often if your event draws large crowds or runs longer. Casper events like county fairs and concerts often use trailers; the upfront cost is higher than standard units, but guests appreciate the comfort and you avoid the smell complaints that sometimes follow small portable toilets at big gatherings.

A residential septic tank is typically pumped every 3 to 5 years, depending on tank size and household size. Heavy use drives the schedule shorter. Watch for slow drains, sewage backups or wet spots in the yard; those are warning signs that pumping is overdue. Casper Porta Pros handles septic tank pumping and grease trap pumping for homes and businesses. A grease interceptor is pumped when fats, oils, grease and solids reach 25 percent of the liquid depth, which happens faster than septic tanks in restaurants and food service. Call us if you're unsure when your tank was last pumped; we can inspect and advise. Emergency septic service is available if a backup happens outside business hours.

Yes, if your crew is applying paints, coatings, herbicides or insecticides, or working with other harmful contaminants. OSHA 1926.51(f)(1) requires washing facilities in those contexts. Beyond contamination, 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 the rule. Casper Porta Pros rents handwashing stations and portable sinks that deliver potable water per OSHA 1926.51(a)(1). We place them near work areas so your crew stays clean and compliant. Trailers with multiple stalls work for large sites; standalone stations work for smaller teams. Ask about handwashing station requirements when you contact us.
