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.

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.
