Horizontal Plastic Water Tanks

Horizontal Leg Tanks – Built for Hauling, Ready for Work
From farms to factories, horizontal leg tanks are trusted across industries for one reason: they get the job done. Designed for safe liquid transport and flat storage, these tanks feature molded-in support legs that double as baffles. This reduces slosh during hauling and increases stability in the field....

Choose from a full range of capacities—from 30-gallon spot sprayer tanks to massive 6025-gallon transport tanks. We source from trusted brands like Norwesco, Snyder, Chemtainer, and Enduraplas. Each elliptical leg tank is rotationally molded from durable polyethylene, UV-stabilized, and built to resist cracks, rust, & sunlight. Most are FDA-compliant, making them safe for potable water, fertilizer, or chemical transport.

Horizontal Leg Tank Buyer’s Guide

Before picking a low profile horizontal tank, consider the following key factors to make sure it fits your needs:

1.Capacity & Footprint

Tank Depot’s horizontal storage tanks range from compact 30-gallon units to massive 6025-gallon haulers. Smaller tanks work great on UTVs or small trailers; larger models need full-length support during transport.

2.Intended Use (Hauling vs. Stationary)

All our horizontal water tanks can be used for hauling or stationary applications, but not for pressurized systems. If you're transporting liquids regularly, opt for models with molded-in baffles, tie-down hoops, and drain fittings.

3.Support Requirements

Most tanks require full-length support when in use. Some larger units (like 1025 or 2600 gallons) come freestanding, but still benefit from hoop kits during movement.

4.Wall Thickness & Resin Type

Choose heavy-duty wall options if your application involves frequent transport or rough handling.

  • Standard Polyethylene (HDPE): Great for water, fertilizers, light-duty chemicals
  • Crosslinked Polyethylene (XLPE): Available for more demanding chemicals or rugged use (May require a minimum run quantity)
5.Certifications & Safetyt

Look for NSF61 certification (potable water), FDA-approved resin, and UV inhibitors for peace of mind indoors or out

6.Accessories & Add-Ons

Need more control or customization? Many tanks support:

  • Custom fitting installation
  • Manway options (6" to 10" vented caps)
  • Skid frames or elliptical cradles
  • Steel tie-down bands
  • Drain valve upgrades
