How many porta potties does a construction site need?
OSHA 1926.51(c) breaks it out by headcount, and it is the number every Cheyenne contractor should start with. At 20 workers or fewer, you need 1 toilet facility. From 20 up to 200 workers, the rule calls for 1 toilet seat and 1 urinal per 40 workers. At 200 workers or more, it drops to 1 toilet seat and 1 urinal per 50 workers. A framing crew of 15 on a residential job near Fox Farm-College, 2.0 miles south of downtown, satisfies the rule with one standard porta potty rental. A 60 worker commercial build needs two units minimum, run against the 40 worker bracket. Check your count against the OSHA portable toilet requirements page before you order, and if you are unsure how a phased job changes your bracket, use the how many porta potties do i need breakdown alongside your super's headcount log. Multi-week jobs in Cheyenne often start small and add units as crew size grows, so recount at every phase change.
How many porta potties does an event need?
Events run on guest count and hours, not worker brackets, and alcohol changes the math fast. Here is a working table for planning an outdoor event in Cheyenne:
| Guests | Duration | No alcohol | With alcohol |
|---|---|---|---|
| 100 | 4 hours | 2 units | 3 units |
| 250 | 4 hours | 4 units | 6 units |
| 500 | 4 hours | 8 units | 10 units |
| 100 | 8 hours | 3 units | 4 units |
| 500 | 8 hours | 10 units | 13 units |
Alcohol service pushes bathroom trips up, so add roughly 20 to 30 percent more units versus a dry event of the same size. A wedding of 150 guests running 6 hours with a bar needs more than the bare guest count suggests, closer to 5 or 6 standard porta potty rental units plus at least one ADA accessible porta potty. For a bridal-style event, pair the count from wedding restroom rental with a deluxe flushable porta potty or two for the wedding party. Multi-day festivals need service scheduled between days, not just more units up front.
How do I adjust for alcohol at an event?
Alcohol raises bathroom trips per guest, and the fix is more units, not bigger ones. Bump your dry-event number by 20 to 30 percent when a bar or open pours are involved. A 250 guest fundraiser that needs 4 units dry should move to 6 with a cash bar running the whole night. Multi-day events compound this: a 3 day festival with drinking each evening needs the same per-day count held steady across all three days, plus a mid-event service call. Cheyenne event planners running anything near festival restroom rental or concert restroom rental scale should build service visits into the contract up front rather than calling when units fill. ANSI/PSAI Z4.3 sets the baseline service interval at once per week for 10 users over a standard 40 hour week, which tells you how fast a unit can fall behind at a drinking event running well past that pace.
How many tons does a 20 yard dumpster hold?
A 20 yard dumpster runs about 22 feet in length on a standard chassis, and it holds a mixed load in the range most residential cleanouts need. Cubic capacity for a 20 yard box works out to roughly 20 times 27 cubic feet, since a cubic yard equals 27 cubic feet, which puts total volume near 540 cubic feet before you account for the shape of the box. Weight capacity depends more on what you are loading than the box size, and mixed construction debris or shingles will hit tonnage limits before the box visually fills. Check dumpster weight limits and 20 yard dumpster rental before you load, especially with dense material like concrete or roofing.
How many tons does a 30 yard and 40 yard dumpster hold?
A 30 yard dumpster and a 40 yard dumpster both run larger footprints, and tonnage again depends on what is going in, not just the box size. Cubic capacity scales the same way as the 20 yard box: a 30 yard container holds about 30 times 27 cubic feet, near 810 cubic feet, and a 40 yard container holds about 40 times 27 cubic feet, near 1,080 cubic feet. Both sizes need roughly 60 feet of straight clearance behind the delivery truck to place the box, so measure your driveway or lot access before booking either size. Renovation projects near Warren AFB, 5.0 miles west of downtown Cheyenne, commonly step up from a 10 yard dumpster rental to a 30 yard dumpster rental or 40 yard dumpster rental partway through demo when debris volume outpaces the smaller box. Full sizing detail lives on dumpster sizes and dimensions.
Does ADA access change my unit count?
Yes, and the rule is fixed regardless of your total headcount. ADA Standards section 213.2 requires that where portable toilets are clustered, at least 5 percent of units must be accessible, with a minimum of one no matter how small the cluster. A jobsite running 10 standard units needs at least one accessible unit added to that count, not swapped in for one of the ten. ADA units also need a wider approach: ADA Standards section 403.5.1 sets a 36 inch minimum clear route, and section 404.2.3 requires a 32 inch clear door opening, so placement matters as much as count. Pair your accessible unit order with the ADA restroom requirements guide and confirm the pad is level, since section 302.1 requires a stable, firm, slip resistant surface under the unit. Cheyenne sites with gravel or turf lots should plan a leveled pad before delivery day.
Should I add handwashing stations separately?
Yes, and construction sites have a specific trigger for it. 1926.51(f)(1) requires washing facilities where workers apply paints, coatings, herbicides or insecticides, or handle other harmful contaminants, and that requirement sits apart from your toilet count entirely. General industry workplaces fall under 29 CFR 1910.141(d)(2) instead, which requires soap and towels or a hand drying device at washing stations, and hand sanitizer alone does not satisfy it. Farm operations near Hillsdale, 21.9 miles east of Cheyenne, fall under a different standard again: OSHA 1928.110 sets field sanitation for hand-labor employees at one facility per 20 workers, reachable within a quarter mile walk. Add a handwashing station rental or portable sink rental alongside your toilet order rather than assuming one unit covers both needs, and check the specifics on handwashing requirements before your next inspection.
How many porta potties for 100 people?
For a 4 hour outdoor event with no alcohol, plan on 2 units for 100 guests. Add a third if alcohol is served, since drinking raises trip frequency. Multi-hour events past 6 hours should add one more unit regardless of alcohol, and always include one ADA accessible porta potty.
How many porta potties per worker on a jobsite?
OSHA 1926.51(c) sets 1 toilet for 20 workers or fewer, then 1 toilet seat and 1 urinal per 40 workers up to 200. Crews near South Greeley, 3.6 miles south of Cheyenne, typically order one unit per 15 to 20 workers to stay ahead of the bracket as crews grow.
How many cubic feet in a 10 yard dumpster?
A 10 yard dumpster holds about 270 cubic feet, based on 10 times 27 cubic feet per cubic yard. It runs a shorter footprint than larger boxes and suits smaller cleanouts. Check 10 yard dumpster rental for footprint and access details before booking.
How many cubic feet in a 40 yard dumpster?
A 40 yard dumpster holds about 1,080 cubic feet, based on 40 times 27 cubic feet per cubic yard. It is the largest standard box most residential and commercial jobs need. See 40ft storage container if you need enclosed storage instead of open debris hauling.
Do I need more units for a multi-day event?
Yes. Multi-day events need the same per-day unit count held steady across every day, not a lower count on later days. Schedule a mid-event service visit rather than assuming units carry over cleanly, especially if alcohol is served each evening. Confirm your service schedule when you book through festival restroom rental or request a quote.
Where do I check local placement rules before I order?
Placement in the public right of way needs confirming with the city of Cheyenne directly, since specific ordinance numbers are not something to guess at. Start with the porta potty placement guide and porta potty permit requirements pages, then call the relevant city department to confirm before delivery day.
