How many restrooms does a farm operation need?
Start with the headcount doing hand labor, not the acreage. OSHA 1928.110 sets the baseline at one toilet and one handwashing facility per 20 employees, and it has to sit within a quarter mile of wherever people are working, not back at the barn. A crew of 15 pickers spread across a field needs the unit moved closer to the actual work zone, not left at the property entrance because that is where the truck could park. For general job-site sanitation counts, the construction standard OSHA 1926.51(c) uses similar ratios: one toilet for 20 workers or fewer, then one toilet and one urinal per 40 workers as the crew grows past that. Farms running a mixed crew, some hand labor and some equipment operation, often end up sizing to the stricter of the two standards. If you are not sure which applies, the how many porta potties do I need guide walks through it, and the OSHA portable toilet requirements page covers both standards side by side. A standard porta potty rental usually covers a single field crew; larger operations spread across several acres often need units at more than one placement point.
What about handwashing on a farm site?
Potable water and a place to wash are not optional on an ag site. OSHA 1928.110 requires potable water alongside the toilet and handwashing facility, and 29 CFR 1910.141(d)(2) is specific that the setup needs soap and towels or a hand-drying device. Hand sanitizer alone does not satisfy that. If your crew handles produce for sale, that washing station also matters for food safety, not just labor compliance. Edison Porta Pros supplies handwashing station rental units built for field use, plus portable sink rental options where a full basin setup makes more sense than a foot-pump station. For operations spraying herbicide or pesticide, a different rule kicks in: OSHA 1926.51(f)(1) requires washing facilities specifically because of contact with paints, coatings, herbicides or insecticides, separate from the general field sanitation rule. If your crew handles any of those, plan for a wash station near the mixing and application area, not just the packing shed. A hand sanitizer station rental can supplement but should not replace the soap-and-water setup where chemical contact is a factor.
Where should units go on a working farm?
Placement drives everything else. A quarter mile walk sounds generous until you are picking the far end of a 40 acre field in July, so most farms end up with two or three placement points rather than one central bank of units near the road. Edison Porta Pros delivers standard units, holding tanks and handwash stations to spots trucks can actually reach; a roll-off or restroom trailer delivery needs about 60 feet of straight clearance behind the truck, which matters on a farm with narrow access lanes between rows or greenhouses. Ground stability matters too on soft field soil, since units need a level, firm spot to sit through a season of daily use. Farms running a packing operation alongside field work sometimes add a portable restroom rental near the packing shed and a separate porta john rental out at the field edge, serviced on different schedules depending on use. Seasonal and harvest operations near Metuchen, 4.6 miles north of Edison, and South Plainfield, 8.9 miles northwest, run the same setup: multiple placement points tied to where the crew actually works that week. For farms with a wastewater need beyond toilets, a septic pumping service or holding tank rental can handle wash-water and greywater the toilets do not touch.
| unit | day | week | month |
|---|---|---|---|
| standard | $100-$350 | $130-$500 | $125-$325 |
| ada | $200-$400 | $240-$400 | not offered |
| storage | not offered | not offered | $100-$250 |
Seasonal farms running through a full harvest often do better on a monthly rate than a string of weekly renewals; the monthly porta potty rental page breaks down when that makes sense. Farms needing an accessible unit for hired help or visitors should check the ADA accessible porta potty page, since ADA Standards 213.2 requires at least one accessible unit in any cluster, even a small one. Storage for tools, packing supplies or seasonal equipment pairs well with the same delivery run; see storage container rental for options.
Do I need a permit for farm restrooms in Edison?
Placement on a working farm usually falls outside the public right-of-way rules that apply to street or sidewalk placement, but confirming with the city is still worth doing before delivery. The porta potty permit requirements page covers what to check.
How often are units serviced during harvest season?
Weekly is standard for lighter use, matching the ANSI/PSAI Z4.3 baseline of one visit per week for up to 10 users over a 40 hour week. Larger crews or packing-shed traffic often need twice-weekly service; ask about a custom schedule when you book.
Can I rent just a handwashing station without a toilet?
Yes. Many farms already have a toilet setup and just need washing capacity added near a mixing area or packing line. A portable sink rental or handwashing unit can be delivered on its own.
What size tank do farm units use?
Standard units carry a 60 to 70 gallon holding tank, enough for a field crew over several days between services depending on headcount.
Do you deliver to farms outside Edison proper?
Yes, including operations near Perth Amboy, 6.1 miles east, and Sayreville, 7.1 miles southeast. Check service areas or request a quote for your exact location.
