TopTank 6000 Litre Cylindrical Water Storage Tank, UV-Stabilized Polyethylene

TopTank 6000 Litre Water Storage

The TopTank 6000 Litre Tank provides a high-capacity solution for potable and non-potable water management on residential and commercial sites. This vertical cylindrical unit features food-grade polyethylene construction. It maintains structural integrity under full hydrostatic pressure while resisting environmental degradation.

Built for the Job

Site supervisors and plumbers specify this storage vessel for high-demand applications including rainwater harvesting, borehole water storage, and emergency fire reserves. The ribbed design enhances the hoop strength of the cylinder. This prevents bulging or wall fatigue over long-term use. Contractors must install this reservoir on a level, reinforced concrete plinth to ensure even weight distribution. The dark pigment in the material blocks light transmission. This effectively prevents algae growth within the water supply.

• Bulk water storage for multi-unit residential developments.

• Buffer tank systems for commercial irrigation and agricultural sites.

• Back-up water supply for industrial facilities and warehouses.

Product Highlights

Seamless Construction

The unit utilizes a rotational molding process to eliminate joints and potential leak points.

Material Specifications

• Manufactured from high-density, food-grade LLDPE for safe drinking water storage.
• Advanced UV-stabilizers protect the polymer chain from sunlight-induced brittleness.

Technical Specifications

What’s Included

• 1 x 6000 Litre Cylindrical Water Tank

• 1 x Heavy-Duty Screw-Down Manhole Cover

On-Site & Workshop Notes

• Always verify the base is a smooth, solid concrete slab at least 150mm thick to support the 6-ton static load.

• Use flexible couplings when connecting rigid PVC pipes to the outlet to allow for slight expansion or vibration.

• Ensure the overflow pipe diameter matches or exceeds the inlet pipe diameter to prevent internal pressure buildup.

• Position the manhole in an accessible area for periodic cleaning and internal inspection of the vessel.
