Sizing sanitation for a crew?
Tell us the headcount, the duration and whether people are working or housed. We will size to the applicable ratio and tell you what licence class moves the unit.
This page quotes federal standards; it is not legal or safety advice. Which standard governs your specific production or site is a determination for your safety team or counsel. What follows is what the standards publish, so you can size a fleet against a real number rather than a habit.
Honeywagons get ordered by feel: a unit for a small day, two for a big one. Two federal standards publish explicit ratios, and they disagree with each other by a wide margin depending on whether your people are working on the site or living on it.
The construction ratio, as published
29 CFR 1926.51 Table D-1 sets the requirement for construction work in three bands.
| Number of employees | Minimum requirement |
|---|---|
| 20 or fewer | 1 toilet facility |
| 20 or more | 1 toilet seat and 1 urinal per 40 workers |
| 200 or more | 1 toilet seat and 1 urinal per 50 workers |
Note the ratio loosens as the crew grows, from one per 40 workers to one per 50 at 200 and above. That is the opposite of most people's intuition, and it means a large production is proportionally less fixture-heavy than a mid-sized one.
The same headcount, two very different fleets
Set the construction table against the temporary labor camp standard, 29 CFR 1910.142(d)(5), which requires "One such unit to each 15 persons, with a minimum of two units for any shared facility."
| People | Working on site — 1926.51 | Housed on site — 1910.142 |
|---|---|---|
| 20 | 1 toilet facility | 2 toilet units, plus 2 shower heads |
| 40 | 1 toilet seat and 1 urinal (1 per 40 workers) | 3 toilet units, plus 4 shower heads |
| 80 | 2 toilet seats and 2 urinals (1 per 40 workers) | 6 toilet units, plus 8 shower heads |
| 120 | 3 toilet seats and 3 urinals (1 per 40 workers) | 8 toilet units, plus 12 shower heads |
| 200 | 4 toilet seats and 4 urinals (1 per 50 workers) | 14 toilet units, plus 20 shower heads |
| 300 | 6 toilet seats and 6 urinals (1 per 50 workers) | 20 toilet units, plus 30 shower heads |
The question that sets the order
A 120-person crew working a construction site needs 3 toilet seats and 3 urinals (1 per 40 workers). The same 120 people housed on that site fall under a standard requiring 8 toilet units and 12 shower heads. Same people, same ground, more than double the fixtures and a bathing requirement that did not exist before. Establish which framework applies before you order anything.
Water comes with rules of its own
Sanitation orders tend to cover toilets and stop. 29 CFR 1926.51 also requires that "An adequate supply of potable water shall be provided in all places of employment.", and it is specific about how that water is presented.
Portable containers "Portable containers shall be capable of being tightly closed, and equipped with a tap. Water shall not be dipped from containers." Drinking water containers must be clearly marked as to the nature of their contents and not used for any other purpose. And plainly: "The common drinking cup is prohibited."
The details that get missed on a busy set
A tap rather than a dipper. Labelled containers used for nothing else. No common cup, and where single-service cups are provided, both a sanitary container for the unused ones and a receptacle for the used ones. None of this is expensive, and all of it is the sort of thing that gets improvised at 5am on a location day unless it is on the order.
Who is legally allowed to move it
A honeywagon is a towed unit carrying liquid, which means its weight is highest when it most needs moving. Under 49 CFR 383.91, Group A covers "Any combination of vehicles with a gross combination weight rating (GCWR) of... 26,001 pounds or more provided the GVWR of the vehicle(s) being towed is in excess of... 10,000 pounds."
Read the GVWR off the plate of the trailer and of the tow vehicle, add them, and check both conditions. Many production waste trailers cross them, and the answer is a Class A CDL holder rather than whoever is free.
The same point applies to repositioning as to delivery. A unit moved between basecamps mid-shoot needs the same licence class it needed on the way in, so a driver budgeted for drop-off only leaves the honeywagon wherever it was first placed.
What most people get wrong: servicing frequency is the real variable
Fixture count is a published ratio and therefore easy. What is not published anywhere, and what actually determines whether the provision works, is how often the unit is serviced against the tank capacity and the crew size.
A unit that satisfies the ratio on paper and gets pumped once across a six-day shoot is not meeting the intent of the standard by day four. Tank capacity times crew size divided by servicing interval is the arithmetic that matters, and it is a conversation with the supplier rather than a figure you can look up.
Ask for the tank capacity, state the crew size and the shoot length, and get the servicing schedule written into the order rather than arranged ad hoc when someone notices a problem.
No rate card, and we are not inventing one
An earlier version of this page carried nine cost ranges for honeywagon rental. None of them was sourced, because no manufacturer, association or regulator publishes a rate for this, and pricing moves with market, duration, configuration and servicing frequency.
What you can fix in advance is the specification: the fixture count the standard requires, the servicing interval you need, and the licence class to move the unit. Take that to a supplier and the quote is against something real.
"The honeywagon call always starts with how many units and I always come back with how many people and are they sleeping there, because those two answers give completely different numbers out of the regulations. And then the one nobody asks: how often is it getting pumped. You can hit the ratio perfectly and still have a problem on day four if the servicing is not in the contract."

Order it in this order
- Establish whether your people are working on site or housed on it. The standards differ sharply.
- Take the headcount through the applicable ratio to get a fixture count.
- If people are housed, add the bathing requirement, which the construction standard does not impose.
- Add the potable water provision, including taps, labelled containers and no common cup.
- Ask the tank capacity and agree a servicing interval against crew size and shoot length, in writing.
- Check the trailer and tow vehicle plates against the 26,001 and 10,000 lb thresholds.
- Budget the driver across the shoot if the unit will be repositioned, not just for delivery.
Frequently Asked Questions
How many toilets does OSHA require on a set or site?
For construction work, 29 CFR 1926.51 Table D-1 requires 1 toilet facility for 20 or fewer employees, then "1 toilet seat and 1 urinal per 40 workers" at 20 or more, and "1 toilet seat and 1 urinal per 50 workers" at 200 or more. A 120-person crew therefore needs 3 toilet seats and 3 urinals under that table.
Why do sanitation requirements change if you house the crew?
Because a different standard applies. 29 CFR 1926.51 addresses sanitation for people working on a construction site. 29 CFR 1910.142, covering temporary labor camps, addresses people housed, and sets toilets at "One such unit to each 15 persons, with a minimum of two units for any shared facility." For the same 120 people that is 8 units rather than 3 seats, so the framework matters more than the headcount.
Does a honeywagon need a CDL driver?
Frequently yes, and often a Class A. Under 49 CFR 383.91, Group A covers a combination with a gross combination weight rating of 26,001 pounds or more where the towed unit exceeds 10,000 pounds GVWR. A loaded waste trailer is heavy, and its weight rises as the tanks fill. Read the GVWR off the plate of both the trailer and the tow vehicle and check the combination rather than assuming.
What are the drinking water rules on site?
29 CFR 1926.51 requires that "An adequate supply of potable water shall be provided in all places of employment." Portable containers "shall be capable of being tightly closed, and equipped with a tap. Water shall not be dipped from containers," and "The common drinking cup is prohibited." Where single-service cups are provided, both a sanitary container for unused cups and a receptacle for used ones are required.
How much does a honeywagon rental cost?
There is no published rate card for this, and rates vary by market, duration, servicing frequency and unit configuration. What can be established in advance is the number of fixtures your headcount requires under the applicable standard, and the licence class needed to move the unit. Fix those, then get a firm quote against a defined specification rather than against a guess at unit count.
