How to Choose the Right Tank Size for Your Next Job Site
Meta Description: Selecting the correct tank size is critical for efficient fluid storage. Learn how to determine the right frac or AST tank size based on job site needs, fluid type, and operational goals.
Choosing the right tank size for your job site isn’t just about capacity—it’s about efficiency, compliance, safety, and cost-effectiveness. Whether you're managing a frac operation in the oilfield, supporting water transfer in agriculture, or installing a fluid containment system for an industrial site, selecting the correct tank size ensures smooth operations and avoids costly downtime. Here’s how to determine the ideal tank size for your next project.
Understand Your Fluid Type and Volume
The first step is knowing exactly what you’ll be storing. Are you handling freshwater, produced water, drilling mud, chemicals, or fuel? Different fluids have unique storage requirements, including compatibility with tank materials and regulations.
Once you’ve identified the fluid type, calculate the expected volume. This will help you determine whether you need a single large tank—like a 21,000-gallon frac tank—or a modular setup with multiple smaller tanks to maximize flexibility.
Evaluate Operational Space and Site Layout
Tank size isn’t just about capacity—it’s also about physical footprint. For example, vertical tanks take up less ground space, making them ideal for confined job sites. On the other hand, horizontal frac tanks are better suited for operations that require fast access and easy fluid transfer.
If your site has limited access or uneven terrain, consider how the tank will be delivered, positioned, and connected to other equipment.
Match Tank Size to Application Needs
Different applications require different tank solutions:
- Oil & Gas: Frac tanks (typically 18,000–21,000 gallons) are standard for storing frac water or flowback fluids. Their high capacity and rugged steel construction make them industry staples.
- Water Transfer & Agriculture: Vertical poly or steel tanks ranging from 5,000–10,000 gallons are often sufficient for irrigation, livestock watering, or water haul-off.
- Industrial Use: Above-ground storage tanks (ASTs) can be customized for chemical compatibility and capacity, whether you need 1,000 gallons or 25,000+ gallons.

Consider Regulatory and Environmental Requirements
Local and federal regulations may dictate minimum or maximum tank sizes for specific fluids, especially hazardous materials. Secondary containment may also be required based on volume thresholds.
BX Tank Supply offers fluid containment solutions that meet compliance standards, ensuring your site is safe and permitted.
Factor in Transport and Budget
Larger tanks mean fewer trips to refill or drain—but they also mean higher transport and setup costs. If you're on a short-term job or working in a remote area, it may be more cost-effective to use multiple smaller tanks that are easier to move and reposition.
Used or refurbished ASTs can also offer a budget-friendly alternative without compromising performance.
