Holding Tank and Water System Rentals for Office and Sales Trailers

A trailer with a restroom still needs somewhere for water to come from and waste to go. Our water and waste systems give construction office trailers, new-home sales offices and remote sites working restrooms where there's no sewer or water line: a fresh-water supply for the sinks and toilets, and a low-profile holding tank that collects what drains out.

Who Uses Water and Waste Systems

General contractors running job-site office trailers, home builders with model-home sales offices, modular classrooms and temporary clinics, and any remote or environmentally sensitive site where a sewer connection isn't possible or isn't allowed yet.

The same system works for a three-month project or a permanent placement, and for a fixed crew or a steady flow of visitors.

Construction Office Trailer Holding Tanks: Size and Pumping

Florida's rule sizes holding tanks by headcount. With pumping twice a week, a 250-gallon tank covers 2 to 3 people working a normal 8-hour day, 4 to 5 people need 500 gallons, and every person past 7 adds 125 gallons. Pump more or less often and the required capacity changes proportionately, and every tank must be pumped at least weekly.

A single portable holding tank can't exceed 300 gallons, so busier trailers and sales centers use more tanks, more frequent pumping, or both. Tell us how many people use the trailer and we'll size the system and set a schedule that keeps it compliant. Our Holding Tank Guide walks through the rules.

Frequently Asked Questions

Can you connect the tank to my office trailer?

Yes. The tank is compatible with most standard plumbing configurations. We'll look at your trailer's setup when we quote.

Do you pump the holding tank?

Yes, on a schedule set around how many people use it, using our own vacuum trucks.

What size holding tank does a construction office trailer need?

Under Florida's rule, with twice-weekly pumping, 250 gallons covers 2 to 3 people, 500 gallons covers 4 to 5, and 750 gallons covers 6 to 7. Pumping more or less often changes the requirement proportionately.
