100 Gallon Portable Water Tank for Truck Beds or Water Storage

This 100-gallon rectangular tank is a compact, reliable solution for water storage and transport—ideal for farms, job sites, or remote locations without access to running water. While it's most commonly used for potable or utility water, it can also safely hold food-grade liquids, agricultural chemicals, and other non-corrosive industrial fluids. Made from FDA-approved, BPA-free polyethylene and molded as a single solid piece, the tank resists leaks, cracks, and UV damage. Its space-efficient shape fits easily in tight areas like truck beds or equipment trailers, making it a dependable option for on-the-go liquid handling in tough environments.

Pro Tip: If you plan to transport liquid in this tank, we recommend the optional hold down bands! The hold down bands include 2 steel bands, 4 J-hook bolts with washers and nuts. They are not required for stationary use.

FDA-Approved for Potable Water
Safe for storing drinking water—meets FDA regulation 21 CFR 177.1520.
Corrosion-Resistant HDPE
Made from high-density polyethylene that won’t rust, corrode, or break down over time.
Flat-Bottom Design
Sits securely on flat surfaces—ideal for trailers, truck beds, or storage areas.
Compact & Low-Profile Shape
Fits easily in most truck beds or tight spaces without tipping.

Seamless, Leak-Resistant Design
One-piece molded construction reduces the risk of leaks and ensures long-lasting performance.
UV-Stabilized for Outdoor Use
Built to handle direct sunlight without cracking or fading.
Algae-Resistant Interior
Opaque material helps block sunlight and slows algae growth inside the tank.
