RotoTank 3500L Cylindrical Water Tank, UV-Stabilized Polyethylene

RotoTank 3500L Cylindrical Tank

The RotoTank 3500L Water Tank provides heavy-duty bulk liquid storage for residential, agricultural, and commercial construction projects. This vertical cylindrical vessel utilizes high-density polyethylene for maximum durability in harsh outdoor environments. It meets food-grade standards for potable water storage and chemical resistance.

Built for the Job

Plumbers and site supervisors select this specific 3500-litre capacity for its balance of footprint and volume. The manufacturing process involves rotational molding, which ensures a seamless, one-piece structure. This design eliminates weak points often found in welded alternatives, significantly reducing the risk of leaks or structural failure under pressure. Contractors rely on this capacity for medium-scale building sites where a consistent supply is mandatory for mixing mortar and general dust suppression. Facility managers often install these in battery configurations to increase total site storage without requiring massive structural changes. The vertical orientation maximizes vertical space, allowing for a smaller footprint on tight job sites compared to horizontal alternatives.

• Potable water storage for residential developments and remote sites.

• Rainwater harvesting systems for agricultural irrigation and livestock.

• Industrial liquid containment for non-corrosive chemical storage.

Product Highlights

Material Durability

High-quality UV-stabilized polyethylene prevents brittleness and cracking from prolonged exposure to direct sunlight.

Seamless Construction

• One-piece rotational molding provides uniform wall thickness.
• Zero seams or joints to prevent structural failure at high fill levels.
• Reinforced ribbing around the cylinder adds lateral strength.

Technical Specifications

What’s Included

• 1 x 3500 Litre Cylindrical Storage Tank

• 1 x Heavy-duty Screw-on Manhole Cover

On-Site & Workshop Notes

• Ensure the installation base is level, compacted, and free of sharp debris before placement to prevent base rupture.

• Use flexible couplings for all plumbing connections to accommodate slight expansion and contraction of the plastic body.

• The unit should be fully drained before any attempt to relocate or lift it to avoid structural stress or injury.

• Check local building codes for required setbacks and drainage overflow management when installing near foundations.
