1000 US gallon HD Polyethylene Underground Water Tank

At this capacity the internal storage surface carries as much importance as the structure around it. The food-grade inner layer is where stored water remains between filling and use, while the insulation layer, external surface and ribbed one-piece body maintain the conditions surrounding it. The features below begin at that inner surface.

Key Features

• Food-Grade Inner Layer: A food-grade internal layer supports potable-water storage, with a smooth surface designed to resist algae and bacterial growth.
• Extra-Thick Thermal Insulation Layer: An extra-thick middle layer helps limit heat transmission from the surrounding ground while contributing stiffness to the tank wall.
• 3-Layer High-Density Polyethylene Construction: Three functional layers combine a UV-stabilised exterior, an extra-thick insulation layer and a food-grade internal surface within one high-density polyethylene body.
• Single-Piece Moulded Body: The 1000 gallon body is formed as a single moulded unit without body joints, supporting dependable structural integrity and leak-resistant construction.
• Reinforced Vertical Rib Structure: Full-height vertical ribs reinforce the tank body, supporting strength and durability in its buried position.
• Non-Porous Polyethylene Material: Non-porous high-density polyethylene supports a rust-resistant and corrosion-resistant body, together with resistance to moisture, soil contact and root intrusion.
• Threaded Protective Cover: A special threaded closure helps protect the stored water by limiting the entry of foreign material from the surroundings when correctly fitted.

Core Product Benefits

• Clean Internal Storage Conditions: A food-grade, growth-resistant inner surface supports water quality throughout day-to-day storage.
• Reduced Heat Reaching the Water: The insulation layer helps limit surrounding heat affecting the stored volume.
• Full Capacity Held Below Ground: Storing 1000 gallon underground keeps the area above the tank usable.
• Manufacturer Warranty: The tank carries a defined 1-year warranty.
