Built around the regulation:

OSHA Worker Ratios for Unit Quantity Planning

OSHA 1926.51(c) requires one portable toilet for every twenty workers during a standard forty-hour week. Our dispatch adjusts these counts based on shift length and access to running water. Crew size and onsite hygiene needs determine the final equipment requirements. We review these job site variables before providing the following unit recommendations.

1 per 20 Workers

One toilet per twenty workers is the baseline for crews of twenty.

Female-Worker Add

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

Urinal Substitution

One urinal counts as one fixture but cannot exceed one-third of the total fixture 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

Active construction sites throughout Columbia receive weekly pump-out service as our standard procedure for crews under twenty workers. Once headcount exceeds thirty or summer temperatures rise, we shift to twice-weekly visits. Our driver removes waste, pressure rinses the tank, replaces the deodorizer puck, and restocks paper. Each visit is logged, providing site supervisors with a clear paper trail for compliance audits mandated by local health codes.

Rough-Site Logistics with Crane-Liftable Units

High-rise builds in Columbia need crane-liftable restrooms with a reinforced steel cage and rigging eyes that move safely between floors — our units ride a crane sling without breaking the seal. The skid-mounted base anchors on gravel or bolts to concrete; relocate as phases progress. Each jobsite unit drains through a suction hose to the waste tank below, with monthly holding tank service per the OSHA 1910.141 sanitation rule for construction worker restrooms.

Construction Site Questions

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

    Two units provide sufficient waste tank capacity for thirty workers under OSHA 1926.51(c), though an ADA unit is required for public-funded or mixed-gender projects.

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

    Monthly contracts get a fixed weekday and route window maintained for the entire life of the building project.

  • + What does monthly billing include?

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

  • + Do you deliver to active concrete pours?

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