Built around the regulation:

OSHA Worker Ratios for Unit Quantity Planning

OSHA 1926.51(c) mandates one portable toilet for every twenty workers on a standard forty-hour shift. Extended hours or the absence of separate hand washing stations require additional units to maintain compliance. Crew size and shift duration dictate the final count for your job site. Review these four categories to determine your specific equipment needs.

1 per 20 Workers

One toilet serves twenty workers during a single shift for small crews.

Female-Worker Add

separate stalls once crews include workers of more than one gender

Urinal Substitution

One urinal counts as one fixture toward the total, up to one-third of required fixtures.

Large-Crew Step

Crews of 200 or more workers require one fixture per 40 workers per shift.

Weekly Servicing Schedules on Active Job Sites

Weekly pump-out service keeps construction sites in Charleston compliant and sanitary for every crew. Our team clears the waste tank and applies a fresh pressure rinse for units hosting fewer than twenty workers. Once headcount exceeds thirty, we transition to a twice-weekly schedule. Our driver replaces every deodorizer puck, restocks toilet paper, and logs the service visit so site supervisors maintain an accurate paper trail for all local audits.

Rough-Site Logistics with Crane-Liftable Units

Charleston high-rise projects need crane-liftable restrooms with rigging eyes and steel cages for deck transfers. Skid-mounted bases anchor to gravel or concrete. Units cycle between floors with intact waste tank seals—our vacuum pumper trucks service sealed tanks without spill risk. Phased projects get multi-floor placement synced to crew movement. Steel-cage designs meet tower crane rigging specs. Monthly contracts ensure units on every active floor per OSHA 1910.141 sanitation rule for construction worker restrooms.

Construction Site Questions

  • + How many units do I need for a thirty-worker crew?

    Two standard units provide enough waste tank capacity for thirty workers under OSHA 1926.51(c), while adding an ADA stall supports mixed-gender crews on public-funded projects.

  • + Can the service day be locked to a specific weekday?

    Monthly contracts secure a fixed weekday and route window maintained for the entire life of your construction project.

  • + What does monthly billing include?

    Delivery, weekly servicing, supplies, and final pickup included plus phase relocations on long-term contracts.

  • + Do you deliver to active concrete pours?

    Concrete pours need the drop scheduled ahead of the pour, staging clear of the forms on gravel, then reposition once the pad cures.
