How many restrooms does a farm or agricultural site need?
OSHA 1928.110 sets the baseline: one toilet facility per 20 hand-labor employees, placed within a quarter mile of where people are working, or a five minute walk. That is stricter than the general construction ratio in OSHA portable toilet requirements, which allows one unit per 20 workers under 1926.51(c) but does not carry the quarter mile rule. On a spread-out property, that distance limit usually decides placement more than headcount does. A 15 acre parcel with crews split across two fields often needs two clusters of standard porta potty rental units rather than one bank near the entrance, even if total worker count would allow fewer under a flat ratio. Fountain Valley Porta Pros walks the property with you, or works from a plot map, to figure out where the quarter mile lines actually fall. We also handle harvest-season surges: if you're bringing in extra hands for a two week picking window, we can scale unit count up and back down without a new contract each time. See our porta potty placement guide for how we think about sightlines, wind direction and tank truck access on working land. For crews that move field to field weekly, ask about emergency porta potty rental for fast redeployment.
What about handwashing on a farm site?
Handwashing service ties directly to the same 1928.110 standard, which requires potable water and handwashing alongside the toilet units, not as an afterthought. We pair handwashing station rental units with every ag toilet cluster, and under 29 CFR 1910.141(d)(2), stations need actual soap and a towel or air dryer. Hand sanitizer alone does not satisfy that. If your crew handles pesticide or herbicide application, OSHA 1926.51(f)(1) requires washing facilities specifically for that exposure, separate from routine field sanitation, and we set those units apart from the general-use stations so there is no confusion about which is which. A portable sink rental works well near packing and sorting stations where hands need washing between tasks, not just at breaks. For crews under 10 people on a single field, ANSI/PSAI Z4.3 sets a baseline weekly service interval for units used across a standard 40 hour week, which is what most small farm operations in Fountain Valley run on. Larger operations or multi-field spreads usually need twice-weekly service instead, and we scope that during setup rather than guessing. If your site also handles product washing or grease from a farm kitchen or stand, a grease trap pumping visit may belong on the same schedule.
Where does farm restroom service fit with septic and storage needs?
Most ag properties around Fountain Valley run existing septic systems for the farmhouse or packing building, separate from the portable units serving field crews. A typical residential-scale tank gets pumped every 3 to 5 years depending on tank size and household or facility use, and our septic pumping service covers that on the same visit as portable unit service if you want one company handling both. If harvest season means temporary housing or bunkhouse use spikes water demand, ask about septic tank warning signs before the system backs up during your busiest week. Some farms also need a holding tank rental for wash water or overflow capacity when the fixed system can't keep pace. On the storage side, seasonal equipment, tools and packing supplies often need a storage container rental parked at field edge rather than hauled back to a barn daily; a 20ft storage container handles most single-crew setups. If you're fencing off a section for pesticide application or keeping livestock out of a treated area, a temporary fence rental does that job, and chain link temporary fence holds up against wind across open acreage better than lighter barrier options.
| unit | duration | typical price |
|---|---|---|
| standard | week | $200 |
| standard | month | $200 |
| service_fee | week | $60 |
Weekly and monthly standard unit rates land close together because most farm contracts run month to month through a season; check monthly porta potty rental for the full breakdown. Full cost detail, including delivery, sits on our porta potty rental cost page.
How far will you travel for a farm property outside Fountain Valley?
We serve properties in Fountain Valley directly and drive to nearby areas regularly, including Midway City about 4.3 miles northwest and Stanton around 8.2 miles north. Call ahead for anything farther and we will confirm the run.
Do you provide ADA-accessible units for farm sites?
Yes. Where units are clustered, ADA Standards 213.2 requires at least 5 percent to be accessible, never fewer than one. See ADA accessible porta potty for unit specs and placement notes.
How often do you service units during harvest season?
Standard interval follows ANSI/PSAI Z4.3, roughly weekly for up to 10 users over a 40 hour week. Larger crews or multi-field operations usually move to twice weekly; we set the schedule during setup.
Can you deliver to a field with no paved access?
Usually, yes. We need roughly 60 feet of clear straight approach behind the delivery truck. Tell us about gates, gravel or soft ground ahead of time so we route the right vehicle.
What if we need restrooms for farm workers and a farm stand event at once?
That is common during harvest. We separate crew-use units from public-facing ones; check festival restroom rental or county fair restrooms for the event side of that setup.
