Construction Site Sanitation Requirements in Saudi Arabia:
What the Law Says and How to Plan
Saudi law requires employers to keep a construction site clean and hygienic, supply drinking and washing water, and provide appropriate toilets. In the sources we reviewed, it does not set a number of toilets per worker. This guide explains what the law does say, where it is silent, and how to size site sanitation for Saudi heat.
It is written for contractors, site managers, and procurement teams who must plan toilets before a crew arrives. Spark Fiberglass, a GRP (glass-reinforced plastic) manufacturer in Dammam, builds portable toilets with onboard water and septic tanks, so we include capacity figures you can check against your own site.

What does Saudi law require on a construction site?
According to the Ministry of Human Resources and Social Development (HRSD), employers must keep the premises clean and hygienic and provide potable and washing water. Summaries of the Saudi Labor Law add a duty to provide appropriate WCs. None of the sources we reviewed states a numeric toilet ratio for construction sites.
The duties we could verify are:
- Clean premises: HRSD says the employer must keep the workplace “clean and hygienic.”
- Water: HRSD lists “potable and washing water” among employer duties.
- Toilets: Clyde & Co summarizes the Labor Law as requiring employers to “provide appropriate WCs.”
- Supervision: HRSD’s Occupational Safety and Health Management Regulation, effective 1 July 2018, calls for supervising the work environment, “such as providing sanitary facilities and canteens.”
Because no figure is stated, “appropriate” is the working test. Your client’s contractor rules may be stricter than the law, so confirm requirements with HRSD, your municipality, and your client before you order.
Who inspects worksite sanitation in Saudi Arabia?
HRSD oversees employers’ obligations to their workers. For worker accommodation, the Saudi workforce-housing firm Sakin reports that the municipality or amanah licenses group housing and Civil Defense sets fire-safety requirements. Sakin is a commercial source and cites no regulation text, so verify with the authority itself.
How many toilets does a construction site need?
Saudi law does not state a number in the sources we reviewed, so planners use benchmarks. The US OSHA (Occupational Safety and Health Administration) table is the most cited: one facility for 20 or fewer workers, then one toilet seat and one urinal per 40. OSHA has no jurisdiction in Saudi Arabia, so treat it as a planning reference, not Saudi law.
| Benchmark | Figure | Applies in Saudi Arabia? |
|---|---|---|
| OSHA 29 CFR 1926.51(c)(1) | 20 or fewer workers: 1 facility. 20 or more: 1 toilet seat and 1 urinal per 40. 200 or more: per 50. | No. US regulation. |
Neither OSHA nor any other foreign figure is a Saudi rule, so state which benchmark your site plan uses and why.
A simple sizing method:
- Count peak headcount. Include subcontractors, not just your own crew.
- Pick a benchmark. Write it into the site plan so the choice is documented.
- Place units near work areas. Crews should not walk far in the sun to reach one.
- Agree a servicing schedule. Put the interval in writing with your supplier.
- Review after the first weeks. Add units if queues form at break times.
How should Saudi heat change your sanitation plan?
Saudi Arabia banned outdoor work in direct sunlight from 12:00 to 3:00 pm between 15 June and 15 September 2026 for private-sector establishments, according to the Saudi Press Agency. Plan sanitation around shifted working hours, shaded units, and reliable water. Arab News reports 95% compliance across 29,945 inspection visits.
That ban has ended for 2026. Check HRSD for next season’s dates.
Our reading, not a Saudi rule: when work shifts into early morning and evening, breaks may bunch together, so queues form at the same hours. If that happens on your site, add units or stagger breaks.
Direct sun also affects the units themselves. Our guide to GRP vs plastic portable toilets explains what UV protection to ask any supplier about.
What applies to labor camps?
Worker camps fall under separate housing rules. According to an abstract of Ministerial Decision 399 of 2007, employers must equip each housing unit with fresh water, a sewage system, and garbage disposal (Article 5), and with equipment proportionate to the number of occupants (Article 6). The abstract gives no fixture ratios, so confirm the numbers in the full Arabic text.
HRSD also states that employers at remote sites, mines, and quarries must provide workers with accommodation, camps, and meals, under conditions the Minister sets.
What should a site sanitation checklist include?
Sanitation plans fail more often on supplies and servicing than on toilet count. A SafeWork SA audit of 168 Adelaide building sites found 90 with toilets that were not clean, hygienic, or conveniently located. At those sites, 64% had little or no soap. These are Australian figures, but the lesson travels.
- Toilets sized to peak headcount, including subcontractors
- Drinking water and washing water available on site
- Soap and a way to dry hands at every unit
- Toilet paper stocked and waste bins in place
- A written servicing schedule agreed with the supplier
- Units close to work areas and safe to reach
- Adequate lighting around units
- Separate facilities where women work on site (a supplier recommendation, not a Saudi rule we found)

Where do Spark's portable toilets fit?
Spark Fiberglass builds two GRP portable toilet models in Dammam, the Regular and the Executive. Each has an onboard water tank and septic tank. The Executive has a slightly larger cabinet and about double the septic capacity of the Regular, which can mean fewer servicing trips.
| Model | Cabinet size | Water tank | Septic tank |
|---|---|---|---|
| Regular | 110 × 110 × 220 cm | 200 L | 425 L |
| Executive | 120 × 120 × 230 cm | 500 L | 850 L |
Specifications as supplied by Spark Fiberglass.
Larger septic tanks matter most on remote sites, where each servicing trip is costly. How many people one unit serves depends on shifts and servicing intervals. Send us your headcount and shift pattern and we will advise. See our portable toilets for construction sites, our compliance guide, and our price factors guide.
What mistakes should you avoid?
The most common planning errors are sizing by headcount instead of peak use, treating a foreign ratio as Saudi law, and leaving servicing unwritten. Each one is avoidable with a documented plan.
- Counting only your own crew and forgetting subcontractors
- Quoting OSHA or a European figure as if it were Saudi law
- Leaving the servicing interval undefined
- Forgetting soap, washing water, and paper
- Placing units in full sun, far from the work face
Frequently Asked Questions
According to HRSD, employers must keep the workplace clean and hygienic and provide potable and washing water. Summaries of the Labor Law add a duty to provide appropriate WCs. We found no numeric toilet ratio for construction sites in the sources we reviewed, so confirm specifics with HRSD, your municipality, and your client.
Saudi law does not state a number in the sources we reviewed. The US OSHA table calls for one facility for 20 or fewer workers, then one toilet seat and one urinal per 40. OSHA does not apply in Saudi Arabia, so use it as a benchmark, size to peak headcount, and document your choice.
HRSD lists “potable and washing water” among the duties employers must provide. The sources we reviewed do not specify volumes or delivery methods. Provide drinking water near work areas and near toilets, and keep a record of how you supply it, especially during hot months.
HRSD oversees employers’ obligations to workers. For group worker housing, Sakin reports that the municipality or amanah issues the licence and Civil Defense sets fire-safety requirements. Confirm which authority covers your project, since industrial zones and project sites may add their own rules.
We found no Saudi servicing interval. The right frequency depends on headcount, shifts, and tank capacity. In the SafeWork SA audit, 39% of non-compliant sites were not regularly cleaned. Agree a written schedule with your supplier, then review it after the first weeks of use.
Yes, seasonally. For 2026, the Saudi Press Agency reported a ban on outdoor work in direct sunlight from 12:00 to 3:00 pm between 15 June and 15 September for private-sector establishments. It has ended for this year. HRSD publishes each season’s details, so check its website before planning summer shifts.
Plan sanitation before your crew arrives
Saudi law sets the duty: a clean site, water, and appropriate toilets. It leaves the numbers to you. Size to peak attendance, state your benchmark, and put servicing in writing.
