Built around the regulation:

OSHA Worker Ratios for Unit Quantity Planning

OSHA 1926.51(c) requires one portable toilet for every twenty workers on a forty-hour week. These counts increase as shifts lengthen or when hand washing stations are absent. Crew size and site access drive the necessary unit count for each project. Our team helps calculate your total requirements based on these specific site variables.

1 per 20 Workers

One toilet per twenty workers is the baseline for a single shift.

Female-Worker Add

Separate stalls when crews include workers of more than one gender.

Urinal Substitution

One urinal counts as one fixture toward the total, capped at one-third of the required count.

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 servicing keeps construction sites in Columbia running without interruption. Our crew performs a full pump-out and pressure rinse for crews under twenty, while higher headcounts trigger twice-weekly visits. Every stop includes a fresh deodorizer puck, paper restock, and a documented log for your compliance audits. We maintain rigorous standards for every unit, ensuring our vacuum pumper truck leaves the site clean after every scheduled service visit.

Rough-Site Logistics with Crane-Liftable Units

High-rise builds in Columbia require jobsite units rigged for tower crane lifts — skid-mounted base with rigging eyes and a reinforced steel cage. The crane sling cycles restrooms deck-to-deck without breaking seal; on grade, anchor to gravel or bolt to concrete. Each unit routes waste tank flow through a holding tank to the suction hose for weekly vacuum truck service, meeting the OSHA 1910.141 sanitation rule for construction worker restrooms. Relocate between phases; monthly construction portable toilet rental pricing covers sites across Richland.

Construction Site Questions

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

    Two standard units provide sufficient waste tank capacity for thirty workers under OSHA 1926.51(c), while adding an ADA stall supports compliance 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 the construction build.

  • + What does monthly billing include?

    Delivery, weekly servicing, paper and sanitizer top-ups, and final pickup with phase relocations on long-term contracts.

  • + Do you deliver to active concrete pours?

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