How many portable toilets do I need for my event or job site?
The math depends on how many people show up and how long they stay. OSHA 1926.51(c)(1) sets the baseline for construction: 1 toilet facility for 20 workers or fewer. Once you hit 20 workers, you need 1 toilet seat and 1 urinal per 40 workers. Hit 200 workers and the ratio tightens to 1 toilet seat and 1 urinal per 50 workers. For events, festivals and gatherings in Costa Mesa, assume one unit per 50 to 75 guests over an 8-hour day. If your event runs longer or you expect heavier use, add one more. Call us with your headcount and we'll size it right. See our guide on how many porta potties you need for the full breakdown.
What's the difference between a standard unit and a deluxe?
A standard portable toilet is about 44 by 48 inches on the ground and stands about 92 inches tall, with a 60 to 70 gallon holding tank. It's the workhorse for construction sites, outdoor events and temporary access. A deluxe unit adds a foot pump flusher, a sink with running water, and a hands-free soap dispenser. For Costa Mesa job sites where crews need to clean hands between tasks, deluxe cuts the infection risk. Compare pricing at our standard porta potty page and deluxe flushable porta potty page. Deluxe costs more but outlasts standard in high-traffic spots.
Do I need an ADA accessible unit?
Yes, if any guest or worker has mobility limits. ADA Standards section 213.2 says where single-user portable toilet units are clustered, at least 5 percent, and never fewer than one unit, must be accessible. An ADA accessible porta potty has a 60 inch diameter turning circle inside, a 32 inch minimum clear door opening per ADA Standards section 404.2.3, grab bars, and a 36 inch minimum clear width route to reach it per ADA Standards section 403.5.1. Costa Mesa venues and construction sites with 10 or more standard units need at least one accessible unit on the pad. We deliver and service them on the same schedule as standard units.
How often do portable toilets get pumped and cleaned?
One service visit per week is the baseline interval for up to 10 users over a 40 hour week, per ANSI/PSAI Z4.3. For heavier use, 30 users or more per week, we service twice weekly. For Costa Mesa events running multiple days, we pump and restock the unit each morning before gates open. Construction sites under OSHA 1926.51(a)(1) also need an adequate supply of potable water on site; we supply handwashing stations with soap and towels per 29 CFR 1910.141(d)(2) so crews can wash hands after handling contaminants. Check our porta potty cleaning frequency page for event-specific schedules.
What does septic pumping cost and how often should I pump?
Residential septic tanks typically get pumped every 3 to 5 years, driven by tank size and household size. A single pumping in Costa Mesa ranges from $150 to $300 depending on tank depth and access. If your tank shows warning signs, slow drains, wet spots in the yard, odors, call immediately; delays cost thousands in repair. Read our septic tank warning signs page and our guide on how often to pump a septic tank for the full picture. We also handle grease trap pumping for restaurants and food trucks.

Can I rent a dumpster for just one day?
Yes. Daily roll-off dumpster rental is available. Typical sizes range from 10 to 40 yards. See our dumpster rental cost page for pricing by size and duration. Delivery needs about 60 feet of straight clearance behind the truck.
Do restroom trailers cost more than standard units?
Yes. A restroom trailer includes multiple stalls, flushing toilets, sinks and climate control. It costs more than standard units but handles high-volume events better. See our restroom trailer cost page for weekend and weekly rates.
What can't go in a dumpster?
