How many toilets do I need for my construction site?
OSHA requires 1 toilet facility for 20 workers or fewer, then 1 toilet seat and 1 urinal per 40 workers up to 200, and 1 toilet seat and 1 urinal per 50 workers at 200 or more, according to OSHA 1926.51(c)(1). A small crew of 8 people needs one standard porta potty. A 60-person job needs at least two units. For events, the math shifts: you'll typically want one unit per 75 to 100 guests, depending on duration. If your job runs multiple shifts, add a unit. Place them within 500 feet of the work area so nobody has to trek across the site. We deliver and service weekly under the baseline ANSI/PSAI Z4.3 interval. Email us your crew size and we'll size the order right.
What's the difference between standard, deluxe and ADA 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's the workhorse for construction and events. A deluxe flushable unit adds a flush mechanism, running water, a sink and a mirror; it costs more but feels like a real bathroom. An ADA accessible porta potty meets ADA Standards section 213.2 with a 36-inch minimum clear width route and a 32-inch door opening, plus a 60-inch turning circle inside per ADA Standards section 304.3.1. You'll need ADA units if your site or event serves the public or employs people with mobility limits. All three are serviced on the same weekly schedule. Deluxe and ADA units cost more because they're harder to move and maintain. Check our rental cost page to see the bands for each type.
When should we pump our septic tank?
A residential septic tank pumped every 3 to 5 years is the baseline, driven by tank size and household size. If you have a large family or run a business from home, pump every 3 years. A household of two might stretch to 5 years. A grease interceptor is pumped when fats, oils, grease and solids reach 25 percent of the liquid depth. Don't wait for a backup or slow drains. Plymouth Porta Pros offers septic tank pumping service with same-day availability most days. We handle residential tanks and commercial grease trap pumping for restaurants and food prep. If you're unsure when you last pumped, we'll inspect and advise. Call for emergency septic service if you have a backup right now.
What can go in a roll-off dumpster?
Most construction debris, demolition waste, and yard waste go in a roll-off dumpster rental. Wood, drywall, concrete, brick, metals and general trash are fine. Hazardous materials, paints, solvents, batteries, tires and appliances are not. Dirt and heavy soil count as a separate load. If you're uncertain, describe the material and we'll tell you whether it fits. A roll-off needs about 60 feet of straight clearance behind the truck for safe delivery. Place it on a flat, level surface away from overhead wires. You can rent by the day, week or month; longer terms bring the per-day cost down. See our dumpster rental cost page for the pricing bands.
Do I need a permit to place a portable toilet in Plymouth?
Placement in the public right of way needs confirming with the city. Call Plymouth's permitting office to learn the local rules. Private property typically needs no permit, but it's smart to verify. We can advise on placement once you know the local requirements. Most construction sites in Plymouth need one somewhere on the property; we'll help you pick a spot that works for safety and access. Contact us with your site address and we'll walk you through it.
How often are units serviced?
One service visit per week is the baseline under ANSI/PSAI Z4.3 for up to 10 users over a 40-hour week. High-traffic events might need twice-weekly or daily service. We pump tanks, restock paper and soap, and disinfect the interior on every visit. Weekend and same-day service costs more than standard weekly. Call Plymouth Porta Pros to arrange the frequency that fits your timeline.
Can I rent a handwashing station?
Yes. Construction sites where employees apply paints, coatings, herbicides or insecticides are required to have washing facilities under OSHA 1926.51(f)(1). Hand sanitizer alone does not meet code; you need water, soap and towels or a hand drying device per 29 CFR 1910.141(d)(2). We rent portable handwashing stations that hook to your water supply. Pair one with your portable toilets for a complete sanitation setup.
What if I need a restroom for an event?
A restroom trailer rental seats 2, 4 or 8 stalls and offers real plumbing, flushing toilets, sinks and mirrors. It's a step up from a portable toilet for weddings, festivals or golf tournaments. Trailers cost more than standard units but feel professional and handle high traffic. See our restroom trailer rental cost page for pricing.
