What does an extra service visit cost and when is it worth adding?

Question

I have a construction site with 25 guys and a standard portable toilet that gets serviced once a week. The crew works a standard 8-hour day, five days a week. The ground is gravel and the unit is right by the gate, so a vacuum truck can get to it no problem. But by Friday afternoon, that holding tank is getting full and it's starting to get ripe, even with the weekly deodorizer recharge. I'm trying to decide if it's worth the extra cost to add a second service visit mid-week.

What does an extra service typically add to the bill? And for a crew this size, is a second pump-out just a luxury or does it actually make a difference in cleanliness and worker satisfaction?

An extra service visit for a standard portable toilet typically costs the same as your weekly service, but the price depends on your contract terms, the rental company's trip fee, and the distance to your site. The cost is driven by the service frequency, not the unit type, since the same vacuum truck and labor are used.

For 25 workers, OSHA 1926.51 requires only one portable toilet, so your setup meets the minimum. However, a single weekly service is often insufficient for a crew that size using the unit five days a week. By Friday, the holding tank is likely near capacity, and odor builds up as the deodorizer depletes. Adding a mid-week service keeps the tank from overfilling, maintains better odor control, and improves cleanliness. It's not a luxury, worker satisfaction and site hygiene matter, and a fresher unit reduces complaints. I've seen crews appreciate it, especially in warmer weather when odors worsen. Check if your rental company offers a discounted rate for additional services on the same contract.
