For most Ankeny job sites, plan on 1 portable toilet per 10 workers over a 40 hour week, or 1 per 20 under OSHA's minimum standard. For events, figure 1 unit per 50 guests for the first 4 hours. Add units for alcohol, multi-day runs, or a mixed crowd. A worked example follows for both.
OSHA 1926.51(c) sets the legal floor: 1 toilet seat for 20 workers or fewer, then 1 seat and 1 urinal per 40 workers once you pass 20, dropping to 1 per 50 once you hit 200 or more. That's a minimum, not a comfort level. Most crews on construction site services in Ankeny order tighter than that because a line at the only unit on site costs more in idle labor than a second toilet does. ANSI/PSAI Z4.3 backs a 1-per-10 baseline for a standard 40 hour week with one weekly service visit, which is the number most supers actually plan around. A 25-person crew, then, needs 1 unit under strict OSHA math, but closer to 3 under the working standard. Check how many porta potties do I need style math against your own crew size, then read the full OSHA portable toilet requirements before you finalize a count, since a state inspector cares about the letter of 1926.51(c), not the comfortable version.
Events run on guest-hours, not headcount alone. A 4 hour event with 200 guests needs roughly 4 units at the 1-per-50 rate; stretch that to 8 hours and you're closer to 6, since bladders don't pace themselves to your schedule. Alcohol service pushes usage up fast, so add 1 unit for every 100 drinkers on top of the base count. A wedding reception in wedding restroom rental planning usually wants at least 1 ADA accessible porta potty per ADA Standards 213.2, which requires at least 5 percent of a cluster to be accessible, never fewer than one. For a county fair or multi-day festival, see festival restroom rental and county fair restrooms for stretch-run counts, and check the event restroom rental page for a broader breakdown by guest count and hours.
| guests | hours | standard units | ADA units |
|---|---|---|---|
| 100 | 4 | 2 | 1 |
| 200 | 4 | 4 | 1 |
| 200 | 8 | 6 | 1 |
| 500 | 8 | 12 | 1 |
Multi-day events and alcohol both push counts up, and skipping that math is how event sites end up with a line by hour two. Add roughly 15 percent more units for each additional day beyond the first if service isn't happening overnight, since a 60 to 70 gallon tank fills faster than most planners expect. Alcohol adds real volume; a beer garden or open bar means adding units at 1 per 100 drinkers on top of your base guest count. Weather matters too, and cold snaps change service needs; read porta potty in winter before locking a plan for a late-fall Ankeny event. If you're mixing a standard fleet with something nicer for VIP areas, the deluxe flushable porta potty line handles that upgrade without changing your base math. For a jobsite running two shifts, don't just double the OSHA table blindly, since 1926.51(c) is calculated per shift population on site at once, not total daily headcount across both shifts.
A standard unit runs $100 to $350 a day depending on term and delivery, with weekly rentals landing between $130 and $500 and monthly terms between $125 and $325, based on measured pricing across 799 datapoints. An ADA unit runs higher, from $200 to $400 a day, since it's a larger footprint and lower-volume order. Multiply your unit count by the term you need, then add a delivery fee, which typically runs $100 to $150 for a day rental and less per unit on a longer term. Full detail lives on porta potty rental cost, and if you're renting daily instead of by the week, porta potty rental per day breaks out that math specifically. Long jobs get better per-day pricing; see monthly porta potty rental if your Ankeny project runs past 30 days.
| unit | day | week | month |
|---|---|---|---|
| standard | 100-350 | 130-500 | 125-325 |
| ada | 200-400 | 120-240 | - |
| deluxe | 85-1200 | 150-290 | - |
Not the same formula, but the same logic: match capacity to the job, not to habit. A 10 yard dumpster holds about 1,350 cubic feet and runs roughly 12 to 14 feet long, good for a single bathroom gut. A 20 yard dumpster holds around 2,700 cubic feet, runs about 22 feet, and carries roughly 3 tons before you hit a weight ceiling worth watching. A 30 yard box holds close to 4,050 cubic feet and can carry up to about 4 to 5 tons depending on debris type, while a 40 yard dumpster holds near 5,400 cubic feet and tops out around 5 to 6 tons on mixed construction waste. Check dumpster sizes and dimensions for the full breakdown, and don't guess on weight; overloading is the single most common surprise fee, covered on dumpster weight limits. If your project also needs secure storage between phases, storage container rental and the 20ft storage container option both run monthly rates between $100 and $250.
Yes, and it runs on a separate track from toilet counts. 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at wash stations; hand sanitizer alone doesn't satisfy it. If your crew is applying paints, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) kicks in specifically for that contaminant exposure, requiring washing facilities beyond general sanitation. Agricultural crews fall under a different standard entirely: OSHA 1928.110 requires field sanitation at 1 facility per 20 hand-labor employees, reachable within a quarter mile walk, which matters for anyone running farm and agricultural restrooms outside Ankeny proper. Pair every toilet cluster with a wash station; see handwashing station rental and the full breakdown on handwashing requirements before you finalize a jobsite plan.
They come from federal minimums and industry service intervals, not guesswork, though Ankeny's own permit rules for placement in a right of way still need confirming with the city directly since that detail isn't standardized nationally. ADA Standards 304.3.1 requires a 60 inch turning circle inside accessible units, and 404.2.3 sets a 32 inch minimum clear door opening, both worth checking before you commit to a single ADA unit on a tight site layout. If Ankeny Porta Pros is delivering to a job near Johnston, about 10.2 miles southwest, or out toward Altoona, roughly 12.5 miles southeast, travel time can affect same-day delivery windows. For jobs further out toward Urbandale or Clive, 16.9 and 18.4 miles southwest respectively, book delivery a day ahead rather than same-day. See porta potty rental in Ankeny or the broader service areas page for coverage details, and request a quote once you've settled on a count.
Plan on 2 standard units for a half-day event, or 1 unit plus 1 ADA-accessible unit if you want to meet ADA Standards 213.2's minimum cluster ratio. For an 8 hour day, move to 3 units since usage climbs with time on site, not just headcount.
A 30 yard dumpster typically carries 4 to 5 tons depending on the material; concrete and shingles hit that ceiling fast, while household debris rarely does. Check 30 yard dumpster rental for load specifics before booking.
Around 2,700 cubic feet, in a box that runs roughly 22 feet long. That's enough for a mid-size room addition or a full roof tear-off on an average house; see 20 yard dumpster rental for sizing help.
A 40 yard dumpster generally holds 5 to 6 tons on standard construction debris, though heavier material like concrete will hit a weight limit before it hits a volume limit. Review 40 yard dumpster rental for full specs.
Yes. Add roughly 1 extra unit per 100 drinking guests on top of your base guest-hour count, since alcohol increases restroom frequency noticeably. A dry event and a beer garden of the same size need different unit counts entirely.
A 10 yard dumpster runs about 12 to 14 feet long, small enough for most residential driveways. Confirm clearance before delivery, since roll-off trucks need roughly 60 feet of straight clearance behind the truck to place it safely.
