RotoTank 2000 Litre Cylindrical Water Tank, UV-Stabilized Polyethylene

RotoTank 2000L Water Tank

The RotoTank 2000 Litre Tank provides a heavy-duty solution for bulk liquid management on residential, agricultural, and commercial sites. Manufactured from food-grade, UV-stabilized polyethylene, this vertical storage vessel handles harsh outdoor exposure without structural degradation. It integrates directly into standard plumbing networks for rainwater harvesting or municipal backup systems.

Built for the Job

Contractors and plumbers specify this cylindrical unit for its one-piece rotational molding, which eliminates seams and prevents leak points under hydraulic pressure. The vertical design optimizes footprint on site, requiring a level concrete plinth for stable installation. It serves as a primary reservoir for borehole water, treated municipal supplies, or chemical storage where polyethylene compatibility is confirmed. The dark interior lining prevents light penetration, effectively stopping algae growth within the stored water volume.

• Potable water storage for residential complexes and remote work camps.

• Rainwater collection systems for irrigation and secondary site use.

• Buffer tanking for high-demand commercial plumbing systems.

Product Highlights

Structural Integrity

The ribbed sidewall design increases hoop strength to resist bulging when the container reaches full 2000-litre capacity.

Material Quality

• UV-stabilized LLDPE prevents brittleness and cracking in high-heat environments.
• Food-grade certified material ensures safe drinking water storage without chemical leaching.

Technical Specifications

What’s Included

• 1 x 2000 Litre Cylindrical Polyethylene Tank

• 1 x Heavy-duty Screw-on Manhole Cover

On-Site & Workshop Notes

• Always install the storage unit on a flat, level concrete base at least 100mm thick to prevent base deformation.

• Ensure flexible couplings are used between the tank outlet and fixed piping to accommodate slight movement during fill cycles.

• Check local building codes for required overflow venting and backflow prevention when connecting to municipal lines.

• Clean the interior annually to remove sediment buildup, especially in rainwater harvesting setups.
