How many portable toilets do I need for my construction crew?
OSHA 1926.51(c)(1) sets the baseline: 1 toilet facility for 20 workers or fewer. From 20 to 40 workers, add 1 toilet seat and 1 urinal per 40 additional workers. At 200 or more workers, the ratio is 1 toilet seat and 1 urinal per 50 workers. The actual count depends on work hours, site layout and whether crews work one shift or overlapping shifts. Mount Pleasant construction sites often split crews across multiple phases, which can lower the total needed. Call Mount Pleasant Porta Pros with your crew size and schedule, and we'll calculate the exact number. For event restroom rental, the math is different: foot traffic, event length and restroom access all matter.
Where can I place a portable toilet on my property or jobsite?
A standard porta potty is roughly 44 by 48 inches on the ground and 92 inches tall, so it fits in tight spaces. The main constraints are drainage (no standing water), level ground, and vehicle access for servicing. Mount Pleasant properties near the marsh need special care because soil saturation changes with tide. If placement needs to cross the public right of way, confirm with the city first: Mount Pleasant has rules about sidewalk and street access that vary by zone. A porta potty placement guide covers the full checklist, including ADA accessible units. For sites needing roll-off dumpster rental, a 60 foot clear path behind the delivery truck matters most.
How often does Mount Pleasant Porta Pros service the units?
One service visit per week is the standard interval under ANSI/PSAI Z4.3 for up to 10 users over a 40 hour week. Heavy-use sites or events need twice-weekly service. Mount Pleasant Porta Pros adds service stops based on usage, not just calendar days. If a unit fills faster than expected, we pull it sooner. Restroom trailers get daily service as part of the rental. For septic pumping, a residential tank is typically pumped every 3 to 5 years depending on household size and tank volume. Grease trap pumping follows different rules: a grease interceptor is pumped when fats, oils, grease and solids reach 25 percent of the liquid depth.
What about handwashing and potable water on job sites?
OSHA 1926.51(a)(1) requires an adequate supply of potable water in all places of employment. If your crew applies paints, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) also mandates washing facilities with soap and towels or a hand drying device at the site. Plain hand sanitizer does not satisfy this rule; you need 29 CFR 1910.141(d)(2) compliant stations. Mount Pleasant Porta Pros rents handwashing stations that run off gravity tanks or pressure systems. A portable sink rental works for small crews; larger sites often pair sinks with portable toilet rental.
Can I rent a unit for just one day or a weekend?
Yes. Daily rates start around $150 and weekend rates run higher because of driving time and crew scheduling. Monthly rental costs less per day if you need the unit for 30+ days. See porta potty rental per day and monthly porta potty rental for current pricing.
What's the difference between a standard unit and a deluxe?
A standard unit has a seated toilet and a urinal. A deluxe flushable porta potty adds an electric flush, hand sanitizer and a larger mirror. Deluxe units cost more per day but feel cleaner to users. Check porta potty rental cost for pricing on both styles.
Do I need an ADA accessible toilet?
If you have employees or public users with mobility issues, yes. An ADA accessible porta potty meets ADA Standards section 213.2 requiring at least 5 percent of single-unit clusters to be accessible, never fewer than one. Accessible units need 36 inch minimum clearance per ADA Standards section 403.5.1 and a 60 inch turning circle per ADA Standards section 304.3.1.
What if I need a bathroom for an event?
Event restroom rental pricing is event-based, not daily. A wedding restroom rental or festival restroom rental typically includes delivery, setup, service during the event and pickup. Restroom trailer rental works for larger events in Mount Pleasant.
How does septic pumping work and what triggers an emergency call?
Mount Pleasant Porta Pros pumps the tank, disposes of waste at an approved facility and leaves the tank clean. Call for emergency septic service if the tank backs up into the house, the drain field pools water or you smell sewage near the house. These are signs the tank or field is failing.
