Concrete Water Tanks

The 20,000L Heavy Duty (HD) Concrete Water Tank is designed for commercial, industrial and residential applications where high-capacity below-ground water storage is required. Engineered for car trafficable areas, and basement applications, it is ideal for stormwater retention and detention systems, rainwater harvesting, pump wells, fire protection and general water storage.

Manufactured in Australia from high-strength concrete reinforced with steel and fibre, every Tanket concrete water tank is built for long-term strength, durability and performance in harsh Australian conditions.

Need more water storage capacity?
Multiple Tanket concrete water tanks can be connected using our Hole Seal System to create a larger, watertight water storage system.

How is the Tank Delivered?
The concrete water tank is delivered in two pieces: the tank and lid. During installation, mastic sealant is applied by your installation team between each section to create a durable, watertight seal.
