Farm and ag operations need one toilet per 20 hand-labor workers, within a quarter mile walk, under OSHA 1928.110. A standard unit runs $130 to $500 a week depending on term length. Pittsburg Porta Pros sets up field sanitation for row crop crews, orchard operations and seasonal harvest sites across Contra Costa County.
The number comes down to headcount and layout, not acreage. OSHA 1928.110 sets the baseline: one toilet facility per 20 hand-labor employees, and it has to sit within a quarter mile walk of wherever the crew is working. On a big parcel that often means two or three standard porta potty rental units spread across different sections rather than one bank near the gate. Pittsburg Porta Pros maps unit placement against your field rows so nobody's walking half a mile at lunch. Potable water has to be available too, per OSHA 1926.51(a)(1), which on most farm sites means pairing units with a handwashing station rental or a portable sink rental nearby. If you're not sure how many units your crew size calls for, our how many porta potties do I need guide walks through the math, and the OSHA portable toilet requirements page covers the full rule set side by side with the general construction standard.
Most ag rentals run weekly or monthly since harvest and planting seasons stretch on. Here's what typical terms look like:
| unit | duration | typical price |
|---|---|---|
| standard | week | $200 |
| standard | month | $200 |
| delivery_fee | week | $100 |
| service_fee | week | $60 |
Weekly service under ANSI/PSAI Z4.3 assumes one visit per week for up to 10 users over a 40 hour week, so a bigger crew or a longer workday may need two visits. Long harvest runs usually make more sense on the monthly porta potty rental rate than paying by the week the whole season. If your operation also runs a farm stand or packing shed with a septic system, we handle that too. Check the septic tank pumping cost page, and if you're unsure on timing, how often to pump a septic tank covers the 3 to 5 year interval most residential-scale tanks run on. Full cost breakdowns for porta potties specifically live on the porta potty rental cost and porta potty rental per day pages.
Placement follows the crew, not the road. Units need firm, stable ground under ADA Standards 302.1 even off pavement, so we look for compacted soil or gravel pads rather than loose furrow dirt. Where a farm employs any hand-labor crew working alongside a public-facing operation, like a fair stand or event, at least one accessible unit should be part of the mix under ADA Standards 213.2. Our ADA accessible porta potty units meet the 32 inch door clearance called for under ADA Standards 404.2.3. Pittsburg sits inland from the water, and delivery trucks reach most farm sites within the county without issue, though we also cover growers near Oakley, about 13.7 miles east, and Brentwood, 14.1 miles southeast. For crews spraying herbicides or pesticides, OSHA 1926.51(f)(1) requires washing facilities for that work specifically, which is a separate need from general field sanitation. Our porta potty placement guide has more on siting units around irrigation lines and equipment paths, and the porta potty in winter page covers cold-season considerations for late harvest or early planting crews.
For larger operations running multiple crews or a packing operation, a restroom trailer rental or 2 stall restroom trailer can serve a central yard while single units cover the fields. Some growers also rent a roll-off dumpster rental for crop waste and packaging, or a storage container rental for tools and supplies during harvest. If you're clearing brush or fencing off a section during replanting, see temporary fence rental. Pittsburg Porta Pros also serves growers near Martinez, 14.8 miles west, and Pleasant Hill, 15.0 miles southwest, for operations that span more than one county line.
Most standard orders go out within a day or two of booking, sooner if you call ahead for emergency porta potty rental during an unexpected crew surge. Rural access roads sometimes need extra routing time, so tell us about gates or narrow lanes when you book.
Yes, if crew size jumps. ANSI/PSAI Z4.3's one-visit-per-week baseline assumes 10 users over 40 hours; a 30 person harvest crew working full days needs more frequent pumping, not just more units.
Only if both fields fall within the quarter mile walk required under OSHA 1928.110. If your rows run long, it's usually cheaper to add a second unit than to have crews walking that distance twice a day.
Yes. A hand sanitizer station rental is not a substitute for real handwashing under 29 CFR 1910.141(d)(2), which calls for soap and towels or a hand-drying device, not just sanitizer.
We handle that separately from portable rentals. See septic pumping service for scheduling, or septic tank warning signs if you're noticing slow drains or odors around the tank area.
Yes. Pittsburg Porta Pros delivers farm and agricultural restrooms across Pittsburg and the surrounding metro, with same-day and next-day drop-off available on most orders.

Standard rentals include scheduled service — a pump-out, a clean, a restock and fresh deodorizer. Busy or hot-weather sites can be serviced more often.
