How many portable toilets do I need?
Worker count determines toilet requirements. OSHA 1926.51(c) specifies 1 toilet facility for 20 workers or fewer; 1 toilet seat and 1 urinal per 40 workers from 20 up; and 1 toilet seat and 1 urinal per 50 workers at 200 or more. For construction sites in Great Falls, that math is straightforward: a 15-person crew needs 1 unit, a 50-person crew needs 2, and a 250-person crew needs 6. Check our guide on how many porta potties you need for the detailed breakdown. Event planners use a different ratio. A festival or wedding with 200 guests might need 4 to 6 units depending on duration. Call us and we'll size your order to the job.
What does a standard porta potty cost per day, week and month?
| Duration | Price Range |
|---|---|
| Daily | $100 to $350 |
| Weekly | $130 to $500 |
| Monthly | $125 to $325 |
| Weekend | $125 to $400 |
Prices depend on how long you rent and how many units you need. A standard porta potty rental in Great Falls runs $100 to $350 per day, with weekly and monthly discounts. Delivery fees apply. If you need an ADA accessible unit, expect to pay $120 to $400 per week. See our full cost guide for all unit types and rental lengths.
What does septic pumping cost and how often should I pump?
Septic pumping in Great Falls costs $150 to $300 per service call. A residential septic tank is typically pumped every 3 to 5 years, driven by tank size and household size. A full tank sits around 1,000 gallons. If you're unsure whether your tank needs pumping, read the warning signs. We also handle grease trap pumping for restaurants and commercial kitchens, where a grease interceptor is pumped when fats, oils, grease and solids reach 25 percent of the liquid depth. Emergency service is available on weekends.
Do I need a permit to place a portable toilet in Great Falls?
Permit requirements vary by location. If you're placing a unit in the public right of way, confirm placement rules with the city of Great Falls before you order. Private property usually has fewer restrictions. We can advise on site-specific questions once we know your address. See our permit guide for common scenarios. Some events and construction projects need different paperwork. Talk to us early so we don't delay your job.
What's the difference between a standard unit and a deluxe model?
A standard portable toilet holds 60 to 70 gallons and measures about 44 by 48 inches on the ground, standing roughly 92 inches tall. A deluxe flushable porta potty offers a flush mechanism, running water, and a hand sanitizer dispenser. Deluxe units cost more per day but feel more like a real restroom. For construction sites in Great Falls where crews work long days, deluxe units cut complaints and improve morale. For short events, a standard unit works fine. Restroom trailers are the top tier: multi-stall, heated, with climate control and full plumbing. Check the cost comparison to see which fits your budget.
