How the calculation works
Estimated truckloads = total gallons ÷ tanker capacity, rounded up to the next whole load, because a partial load still needs a trip.
Gallons per load spreads the total evenly across those loads, so the last truck is not left nearly empty on paper. Trips per truck divides the loads across the number of trucks and rounds up.
Example
45,000 gallons with a 4,200-gallon tanker → 45,000 ÷ 4,200 = 10.7, rounded up to 11 loads of about 4,091 gallons each. With 3 trucks, each truck runs about 4 trips.
Choosing a tanker capacity
Tanker sizes vary widely by trailer type, state weight limits and road restrictions. Many highway water tankers carry somewhere in the 3,000–5,000+ gallon range, but legal payload depends on the truck, axle configuration and fluid weight.
The default in this calculator is only a starting point — it is not a description of Contractor Transport's equipment. Enter the capacity your dispatcher confirms.
What changes real-world load counts
- Fluid weight: produced water and brine are heavier than fresh water, so a truck may hit its legal weight before its volume limit.
- Site access, wait times at loading and disposal points, and round-trip distance.
- Seasonal road postings and frost laws that reduce legal axle weights.
- Whether trucks can be loaded to full capacity at the source.
Frequently asked questions
Why does the calculator round loads up?
Each partial load still requires a full trip, so the estimate rounds up to the next whole load.
Can I enter a custom tanker size?
Yes. Enter any capacity in gallons. Use the figure your carrier confirms for your fluid and route.
Does this give me a price?
No. It estimates loads and trips only. Pricing depends on distance, wait time, disposal and scheduling — request service for a quote.
