TopTank 7500L Cylindrical Water Tank, UV-Stabilized Polyethylene

TopTank 7500L Cylindrical Tank

The TopTank 7500L Water Tank provides high-capacity liquid storage for commercial, agricultural, and residential plumbing installations. This vertical vessel utilizes food-grade Linear Low-Density Polyethylene (LLDPE) to ensure safe potable water containment. The UV-stabilized exterior prevents structural degradation from intense solar exposure during long-term outdoor placement.

Built for the Job

Contractors specify this 7500-litre reservoir for sites requiring significant water reserves without the footprint of multiple smaller units. The vertical cylindrical profile optimizes ground space while maintaining a stable center of gravity. Site supervisors often deploy these units for construction water supply or borehole integration. The heavy-duty wall thickness withstands the hydrostatic pressure of a full load. This storage solution serves as a primary hub for rainwater harvesting systems in large-scale developments. Plumbers appreciate the molded-in technical features that simplify the installation of standard inlet and outlet fittings.

• Bulk potable water storage for multi-dwelling residential blocks.

• Agricultural irrigation buffering and livestock watering systems.

• Industrial process water backup and fire-fighting reserve supply.

Product Highlights

Double-Layer Construction

The black outer layer blocks sunlight to prevent algae growth while the white inner lining allows for easy water level inspection.

Structural Integrity

• Integrated circumferential ribs reinforce the cylinder against bulging.
• Molded manhole cover provides a secure seal against contaminants.

Technical Specifications

What’s Included

• 1 x 7500 Litre Cylindrical Storage Tank

• 1 x Heavy-Duty Threaded Manhole Cover

On-Site & Workshop Notes

• Always install the container on a level, reinforced concrete base at least 100mm thick to prevent uneven stress points.

• Use flexible pipe couplings for all plumbing connections to accommodate natural expansion and contraction of the plastic material.

• Ensure the vessel is properly vented during high-volume filling or discharge to prevent vacuum-induced structural failure.

• Do not drag the unit across abrasive surfaces; use proper lifting equipment and straps when positioning the empty tank on the pad.
