600 US gallon HD Polyethylene Underground Water Tank

Structural design is the starting point for this 600 gallon model. The reinforcing ribs shape the tank body and stiffen the wall across its height, while the 3 functional layers behind them address heat, external exposure and water contact. The features below set out how each element contributes to storage below ground.

Key Features

• Reinforced Vertical Rib Structure: Wide vertical ribs run from top to bottom of the tank body, adding structural strength and durability for its intended underground installation.
• Extra-Thick Thermal Insulation Layer: The extra-thick middle layer helps reduce heat transmission from the surrounding environment while adding stiffness to the tank wall.
• 3-Layer High-Density Polyethylene Construction: The tank body combines a UV-stabilised outer layer, an extra-thick thermal-insulation layer and a food-grade inner layer, giving each part of the wall a defined role.
• Single-Piece Moulded Body: The 600 gallon tank is moulded as one continuous body without joints, supporting structural integrity and leak-resistant construction across the shell.
• Non-Porous Polyethylene Material: The non-porous high-density polyethylene body resists rust and corrosion and supports resistance to moisture, soil contact and root intrusion.
• Food-Grade Inner Layer: The food-grade inner layer is suitable for potable-water storage, while its smooth surface is designed to resist algae and bacterial growth.
• Threaded Protective Cover: The special threaded cover helps limit the entry of surrounding foreign material and protects the stored water when correctly closed.

Core Product Benefits

• Structural Support Below Ground: The rib design adds strength to the buried tank body without relying on additional fitted components.
• Reduced Heat Reaching Stored Water: The insulation layer helps limit the impact of surrounding heat within the documented construction.
• Surface Area Preserved: A 600 gallon volume held below ground keeps the space above the tank usable for other purposes.
• Defined Support Period: A 1-year warranty applies to the tank as supplied.
