Holding Tank Rental for Office Trailers

Most job site office trailers come with a real toilet and sink, but no sewer to drain into. That is where a holding tank (also called a waste tank, wastewater tank or sewage holding tank) comes in. Fort Wayne Porta Potty Rental delivers the tank, hooks it to your trailer’s drain line, and keeps it pumped on a schedule so your crew never has to think about it.

Office Trailer Holding Tanks, Delivered and Serviced

Our standard holding tank is a 300-gallon low-profile tank that sits flat on the ground next to the trailer. It is only about 16 inches tall, roughly 5 feet wide and 8 feet long, so it tucks out of the way on tight sites. When a project needs more capacity, we connect tanks together.

• Capacity: 300 gallons per tank, expandable by linking tanks
• Size: about 16 in. high x 60 in. wide x 95 in. long
• Works with: construction office trailers, restroom trailers, shower trailers, campers and other units with a drain line
• Service: scheduled pump-outs, plus on-call pumping when you need it

Need running water too? Pair the holding tank with one of our fresh water systems and the trailer’s sink and toilet work like they would on city water.

Holding Tank Pump-Out Service

We set a pump-out schedule based on how many people use the trailer, then adjust it as the crew grows or shrinks. If the tank fills up faster than expected, call or text and we will come out. We also pump holding tanks we did not install, so if your trailer company dropped off a tank and left you on your own, we can take over the service.

How Long Will a 300-Gallon Holding Tank Last?

The biggest factor is the toilet in the trailer. A standard household-style toilet uses about 1.6 gallons per flush, while an RV-style or low-flow toilet uses a fraction of that. Hand washing adds a little more. As a rough guide for a 300-gallon tank:

• 5 workers, standard flush toilet: about 1 to 2 weeks between pump-outs
• 10 workers, standard flush toilet: about 1 week
• 10 workers, RV-style low-flow toilet: often 2 weeks or more

Money-saving tip: many office trailers ship with full-flush toilets that fill a holding tank fast. If your trailer supplier offers an RV-style toilet, ask for it. It can cut your number of pump-outs dramatically over a long project.

Holding Tank FAQs

What is a holding tank for an office trailer?

It is a portable waste tank that collects wastewater from an office trailer’s toilet and sink when there is no sewer hookup. We deliver the tank, connect it to the trailer’s drain line and pump it out on a schedule.

How big are your holding tanks?

Our standard tank holds 300 gallons and sits low to the ground, about 16 inches tall, 5 feet wide and 8 feet long. Tanks can be connected together when a site needs more capacity.

How often does a holding tank need to be pumped?

It depends on how many people use the trailer and what kind of toilet it has. A 300-gallon tank serving 10 workers with a standard flush toilet may need pumping about once a week. The same crew with a low-flow RV-style toilet can often go two weeks or more.

Do you pump tanks you did not install?

Yes. We pump holding tanks for office trailers, restroom trailers and job site setups across northeast Indiana. Call or text (260) 460-7546 to get on our pump-out schedule.

Do you also supply fresh water?

Yes. We can pair a holding tank with a fresh water tank so your office trailer has running water for the sink and toilet.
