330 Gallon Water Tank in Black – Durable Water Storage for Tight Outdoor Spaces

This 330-gallon tank is a compact, rugged solution for outdoor water storage. The black color helps block sunlight to slow algae growth, and its space-saving footprint fits easily beside sheds, garages, or garden plots. At 4 feet wide and just under 4 feet tall, it’s built for durability in small areas.

Made for Potable Water

This tank is made from FDA-approved, BPA-free HDPE and meets U.S. regulation 21CFR 177.1520 for storing drinking water safely.

Strong One-Piece Construction

Rotationally molded as a single piece, this tank has no seams or weak points—ideal for leak-free, long-term use outdoors.

UV Protection Built In

The black exterior reduces light penetration to help prevent algae growth, while also resisting fading or damage from direct sun exposure.

Ready to Connect

Includes a 16 inch threaded lid with breather valve, plus 2 inch NPT fittings at the top and bottom for easy setup with your valves or hose system.

Always inspect the tank before signing for delivery.

Offloading Instructions

Liftgate service is widely available and ideal for the easiest delivery experience
If liftgate is not selected, this tank can often be safely unloaded by hand
While this is not an official recommendation by us, at 65 pounds, many customers choose to:
- Lift the tank off the pallet and carry it down with 1-2 people
- Roll it off carefully onto grass or another soft surface
- As always, use caution and proper lifting technique - injury or damage is still possible without the right help or setup
