FLoating ROOF tanks

Two large circular water tanks with people around them in a rural setting.

High-volume liquid storage solutions featuring a practical floating roof cover are vital for ensuring protection, efficiency, and long-term performance. 


The Floating Roof Tanks are specifically designed for agricultural irrigation storage, offering substantial above-ground capacity for irrigation water, agricultural liquids, and effluent-management applications. These innovative floating roof tanks adjust to the liquid level, effectively minimizing evaporation, reducing algae growth, and protecting stored contents from external contamination. 


With configurations available for up to 6 million litres, these high-volume liquid storage tanks provide a practical solution for projects requiring significant capacity, efficient installation, and adaptable site designs. Their modular flatpack construction allows for easy transport to remote, restricted-access, and international locations, while a variety of fittings enables each system to be customized to meet specific operational needs.

Features & Benefits

Two large circular water treatment tanks in a rural area.

Floating roof tanks, equipped with a floating roof cover, adjust with the liquid level to minimize evaporation, reduce algae growth, and limit external contamination. These tanks are perfect for agricultural irrigation storage, offering extremely high-volume liquid storage capabilities with configurations available up to 6 million liters, effectively meeting major agricultural liquid and effluent-storage requirements. The large-scale above-ground design allows these tanks to be constructed up to approximately 3 meters in height and 48.9 meters in diameter, providing significant high-volume liquid storage without the necessity for below-ground works. The modular flatpack construction simplifies transport and containerization, enabling easy delivery to remote, restricted-access, and export-driven project sites. Efficient installation is facilitated by modular assembly, allowing setups to occur within approximately 1–7 days, depending on the site preparation and project specifications. The reduced groundwork requirement means that, under suitable conditions, the tank system can avoid the need for extensive concrete foundations, helping to lower installation time, costs, and construction impact. Above-ground storage is particularly suitable for challenging sites impacted by high water tables, soft soils, floodplain conditions, or restricted access, contingent upon technical assessment. Engineered for ground-movement resilience, this modular design accommodates ground movement and has demonstrated reliable earthquake performance, ensuring dependable storage in demanding environments. Additionally, these tanks are non-corrosive and low maintenance, designed to resist rust and rot, making them suitable for exposed or high-salt environments with minimal ongoing maintenance requirements. The flexible and relocatable nature of the tanks permits multiple configurations, allowing for the structure to be moved if operational or temporary storage needs change. Configurable connections and fittings include base drains, additional inlets and outlets, level indicators, wash-down systems, ground anchors, tanker connections, access hatches, anti-vortex plates, valves, and stainless-steel fittings. With a robust 25-year design life, these systems deliver long-term infrastructure value for high-volume storage and environmental management requirements.

FLOATING ROOF Tanks

Agricultural irrigation storage solutions, such as floating roof covers, are crucial for managing dairy effluent storage and optimizing green-water management. These high-volume liquid storage systems address the needs of sites in floodplains and with high water tables, as well as supporting remote and export-led infrastructure projects. It's essential to verify compliance-led applications in this field for their effectiveness.
