Choosing the Best Portable Water Tank for Your Needs

Not sure which tank fits your application? Use the guide below to narrow your selection based on how and where you plan to use your tank.

Consider Your Capacity Needs
  • Small Tanks (15–100 gallons): Ideal for light-duty use, such as gardening, pressure washing, or UTV/ATV mounting.
  • Mid-Range Tanks (150–300 gallons): Great for hauling water to livestock, off-grid cabins, or RV use.
  • Large Tanks (400+ gallons): Built for commercial hauling, job sites, and high-volume storage.

Will You Need a Pump, Hose, or Tank Add-Ons?

  • Choose mobile tanks compatible with pump systems if you need pressurized flow for pressure washers or irrigation.
  • Add-on hose kits are available for models with threaded outlets.
  • Some tanks can be fitted with wheel kits for increased mobility on job sites or around large properties.

Understand Fittings and Material Grades

  • Look for FDA-approved polyethylene if you plan to store potable water.
  • For non-drinking applications (e.g., gray water, irrigation), standard UV-resistant poly tanks are sufficient.
  • Check outlet compatibility with existing equipment—common outlet sizes are ¾" and 2", while most tanks feature 8" fill caps.

Match the Tank to Your Transport Setup

  • Flat bottom utility tanks are stable and versatile for carts, trucks, and sheds.
  • Horizontal leg tanks mount securely on ATVs or trailers.
  • Elliptical and cylindrical tanks are built to distribute weight evenly for safer hauling at scale.
