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.

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.
