"A site without proper sanitation isn't a site that runs on time."
There's a difference between renting a porta potty and renting a porta potty that actually serves a working crew.
The first one shows up two days late. Smells by Wednesday. Gets ignored by the rental company until somebody finally calls and complains. The crew loses fifteen minutes every shift walking off-site to find a bathroom. The job runs over.
The second one is delivered the day before mobilization. Restocked on a fixed schedule that matches the crew size. Inspected weekly. Replaced before it becomes a problem instead of after.
In Weldon Spring, MO, where construction timelines are tight and OSHA inspections aren't theoretical, the difference between those two rentals shows up in dollars, in days, and in crew morale. We run the second one. There isn't a third option.

OSHA's baseline is one unit per 20 workers, but real-world factors push that ratio higher. We calculate based on crew size, shift length, gender mix, and project duration. Most Weldon Spring, MO sites run one unit per 10 workers in practice.
Weekly is the standard for crews up to 10. Twice-weekly for crews up to 20. Daily service for crews over 20 or 24-hour operations.

"We've used four porta potty companies in Weldon Spring over the last decade. A1 is the only one that actually shows up on the day they say they'll show up. That's the entire bar, and most of the industry doesn't clear it."
"Our crew lost a unit to vandalism on a Saturday night. Called A1 at 7 a.m. Sunday. Replacement was on-site by 11:30. That's the response speed I'm paying for."
"OSHA inspector showed up unannounced on day 47 of a Weldon Spring, MO public works project. We had service logs going back to mobilization, ADA-compliant placement, and hand-wash stations on every cluster. Inspection took 12 minutes. A1's documentation was the reason."
If your crew is mobilizing in the next 30 days, we recommend reserving a service slot now. Our Weldon Spring routes fill in 30-day blocks.
