How many portable toilets does a construction site need?
It depends on your crew size. OSHA 1926.51(c) sets the standard: one toilet facility for 20 workers or fewer, then one toilet seat and one urinal per 40 workers from 20 up to 200, and one toilet seat and one urinal per 50 workers once you hit 200 or more. A site with 30 people needs two units; a site with 60 needs three. Amherst Porta Pros calculates this at the estimate stage so you're never short. If your job is temporary or shifting crews, standard porta potty rental on a weekly schedule works better than monthly. Many sites also add an ADA accessible unit to stay compliant.
What's the difference between a standard unit and a deluxe portable toilet?
A standard unit is about 44 by 48 inches on the ground and holds 60 to 70 gallons. It has a simple toilet, urinal, and hand sanitizer dispenser. A deluxe flushable porta potty adds a foot-flush toilet valve, better ventilation, and sometimes interior lighting. Deluxe units cost more per day, but they're worth it for upscale events, film sets, or client-facing jobsites where appearance matters. Amherst Porta Pros cleans both on the same weekly service schedule, so maintenance is simple either way.

When should I pump my septic tank?
A residential septic tank is typically pumped every 3 to 5 years, driven by tank size and household size. If you have a larger household or notice slow drains, odors, or wet spots in the yard, call sooner. Amherst Porta Pros handles septic tank pumping on emergency schedules too. Don't wait for a backup; it's messy and expensive to fix. We also pump grease traps for restaurants and commercial kitchens where fats, oils, and solids reach 25 percent of the liquid depth.

What can't go in a roll-off dumpster?
Hazardous waste is off-limits: paint, batteries, propane, asbestos, fluorescent bulbs, tires and oils. Amherst building sites and demolition crews know the rules, and Amherst Porta Pros enforces them. Check our guide to what cannot go in a dumpster for the full list. Most contractors rent construction dumpsters by the week; a 20-yard dumpster is standard for mid-size jobs. If you're unsure whether something belongs in the bin, ask before you toss it.
| Unit Type | Daily | Weekly | Monthly |
|---|---|---|---|
| Standard Portable Toilet | 100-350 | 130-500 | 125-325 |
| Deluxe Flushable | 85-1200 | 150-290 | Not available |
| ADA Accessible | 200-400 | 120-240 | Not available |
| Roll-Off Dumpster | 51-112 | 426-778 | 91-500 |
| Storage Container | Not available | Not available | 100-250 |
How do I get an ADA accessible portable toilet on my Amherst site?
Request it when you call. An accessible unit is wider, with a 36 inch clear route inside per ADA Standards section 403.5.1, grab bars, and a 32 inch door opening. ADA Standards section 213.2 says that where single-user units are clustered, at least 5 percent (never fewer than one) must be accessible. Restroom trailer rental also works for large events; a 4-stall model includes one accessible stall built in. Amherst Porta Pros includes delivery and setup in the rental price.

Do I need a permit to place a portable toilet in the public right of way?
That placement needs confirming with the city. Municipal rules on street frontage and sidewalk clearance vary by location, and Amherst's code may differ from neighboring towns like Tonawanda or Niagara Falls. Call or email Amherst Porta Pros to confirm your address before you order. We'll advise whether your lot allows street placement or whether the unit must stay on your property.
What's the fastest way to rent equipment?
Call Amherst Porta Pros with your job details and location. We deliver standard units within 24 hours on most orders, and emergency porta potty rental is available for urgent situations. Online request a quote if you prefer email first. For large events, plan 2 to 4 weeks ahead so we can reserve the right mix of units and schedule delivery. Rush fees apply to same-day requests.
Can I rent a handwashing station separately?
Yes. OSHA 1926.51(a)(1) requires an adequate supply of potable water on all construction sites. A handwashing station rental includes soap and towel dispensers; 29 CFR 1910.141(d)(2) requires soap and hand drying devices, and hand sanitizer alone doesn't meet code. Amherst Porta Pros delivers units with cold water and includes service every week. Pair one with a portable toilet for a complete setup.
