How many portable toilets does my job site need?
OSHA 1926.51(c)(1) sets the minimum: 1 toilet for 20 workers or fewer, then 1 toilet and 1 urinal per 40 workers up to 200, and 1 toilet and 1 urinal per 50 workers at 200 or more. A small crew doing a 2-week renovation needs 1 standard porta potty. A 35-person crew needs at least 2. Events in Detroit often need more units than you'd think because people use them in bursts. Read our guide on how many porta potties to rent for crew size, event type, and duration. The math changes based on whether your site runs 8 hours or 24 hours per day.
What's the difference between standard and deluxe portable toilets?
A standard porta potty has a 60 to 70 gallon holding tank and sits about 44 by 48 inches on the ground. It works for any job. A deluxe flushable unit has a real flush mechanism, a larger tank, and hand soap dispensed inside. Deluxe units cost more per day and per week, which makes sense for office parks, weddings, and long-term rentals. For a 3-day construction job in Detroit, standard units work fine. For a wedding restroom rental or a 2-month site office, deluxe is worth it.
Do I need an ADA accessible portable toilet?
If your site has any employee or public user with a mobility disability, yes. An ADA accessible porta potty meets ADA Standards section 213.2, which requires that where single-user units cluster, at least 5 percent and never fewer than one must be accessible. The door opening is 32 inches wide (ADA Standards section 404.2.3), the route to it is 36 inches wide (ADA Standards section 403.5.1), and there's a 60 inch turning circle inside (ADA Standards section 304.3.1). Detroit construction sites with 10 or more workers often need 1 accessible unit even if only 1 worker requires it. Event sites in Detroit should place accessible units near the main entrance.
What does septic pumping cost and how often is it needed?
A residential septic tank is typically pumped every 3 to 5 years based on tank size and household size. Septic pumping service in Detroit runs between 150 and 300 dollars per service call, depending on tank size and access. If you notice slow drains, backups, or wet spots in your yard, call for emergency septic service right away. A grease trap pumping for a restaurant follows different rules: the trap gets pumped when fats, oils, grease and solids reach 25 percent of the liquid depth, which can be every 2 to 4 weeks depending on volume.
How often are portable toilets serviced?
One service visit per week for up to 10 users over a 40 hour work week is the baseline interval set by ANSI/PSAI Z4.3, the portable sanitation service standard. If you have more users or longer hours, the site needs more frequent service. Many Detroit construction crews ask for twice-weekly service on hot days or high-traffic sites. A restroom trailer rental with multiple stalls requires service 1 to 2 times per week. Event restroom rental for festivals and concerts needs service every 4 to 8 hours depending on foot traffic.
What about handwashing on site?
Where workers apply paints, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) requires washing facilities. A handwashing station and portable sink must have soap and a towel or hand drying device (29 CFR 1910.141(d)(2)); hand sanitizer alone does not meet the rule. Detroit sites using these materials need the sink within easy reach of the work area.
Can I rent a dumpster for demolition?
Yes. Roll-off dumpster rental works for demolition, construction waste, junk removal, and renovation debris. Different materials have weight limits and some items cannot go in a dumpster. Read what cannot go in a dumpster before you load. A roll-off delivery needs about 60 feet of straight clearance behind the truck, so plan your site layout early.
How do I rent a restroom trailer for an event?
Call Detroit Porta Pros with your date, location, and expected guest count. A 2 stall restroom trailer works for 50 to 100 people at an outdoor wedding or small festival. Larger events rent 4 stall or 8 stall trailers. Trailers need a level pad and access for delivery; most sites in the Detroit area work fine.
What's the cost difference between daily, weekly and monthly rentals?
Weekly rental costs less per day than daily rental. Monthly rental costs less per day than weekly. This applies to porta potty rental cost, dumpster rental cost, and restroom trailer rental cost. If you're unsure of your dates, ask about a quote that includes a cancellation window.
