TopTank 3500 Litre Cylindrical Water Storage Tank UV Stabilized

TopTank 3500L Cylindrical Tank

The TopTank 3500 Litre Tank provides a high-capacity vertical storage solution for potable water on residential, agricultural, and commercial sites. This vessel utilizes linear low-density polyethylene (LLDPE) to ensure high impact resistance and long-term durability in outdoor environments. It functions as a primary reservoir for rainwater harvesting or municipal backup systems.

Built for the Job

Site supervisors and contractors specify this volume for medium-sized residential projects or commercial facilities requiring a consistent water supply. The cylindrical profile optimizes the footprint while providing significant vertical storage capacity. It integrates into gravity-fed systems or pressurized pump circuits without structural fatigue.

• Installation on reinforced concrete slabs for static load management in urban developments.

• Rainwater harvesting systems for agricultural storage or industrial landscape irrigation.

• Backup water supply for multi-unit housing complexes or light commercial office blocks.

Product Highlights

Monolithic Construction

The unit is manufactured through a rotational molding process to create a seamless body that eliminates joints or weak points.

Material Specifications

• UV-stabilized outer layer prevents polymer degradation from direct tropical sunlight.
• Food-grade inner liner ensures water remains safe for human consumption and potable use.
• Algae-resistant interior prevents light penetration to maintain water quality over time.

Technical Specifications

What’s Included

• 1 x 3500 Litre Cylindrical Storage Tank

• 1 x Heavy-duty threaded manhole cover

On-Site & Workshop Notes

• Ensure the mounting surface is level and free of sharp debris to prevent stress fractures in the base.

• Plumbers must use flexible couplings when connecting rigid PVC or PPR pipes to the outlet to accommodate thermal expansion.

• Always vent the storage unit properly to prevent vacuum collapse during high-flow pump discharge.

• Storage of industrial chemicals or fuels requires verification of material compatibility with the manufacturer before installation.
