Plastic Water Tanks

Looking for affordable, dependable water storage? Our plastic water tanks — also known as poly water tanks or water poly tanks — are built from high-density polyethylene (HDPE), a step above standard poly tanks. HDPE delivers superior strength, UV resistance, and food-safe quality, making these tanks the trusted choice for long-term water storage. Ideal for off-grid living, RVs, mobile setups, or anyone needing tanks that are both lightweight and built to last.

What makes these poly plastic water tanks great?

UV-stabilized to resist sun damage and extend tank life
One-piece, rotationally molded design reduces leak points
FDA-approved and BPA-free for potable water use
Available in 250–3000 gallon capacities; combine multiple tanks for unlimited storage
