Concrete Water Tanks

The 11,075L Extra Heavy Duty (XHD) Concrete Water Tank is designed for commercial, industrial and residential applications where below-ground water storage is required. Engineered to withstand heavy vehicle loading, including semi-trailers and B-double trucks, 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 Does the Modular System Work?
The modular concrete water tank is delivered in two pieces: the base and lid. During installation, mastic sealant is applied by your installation team between each section to create a durable, watertight seal. Once assembled, the tank is ready for backfilling and performs as a single concrete water tank.
