overview
Orca’s above-ground self-bunded tanks are fully factory-assembled storage units that combine an inner primary tank with an outer secondary containment, eliminating the need for costly concrete bunding or civil works on site.
Manufactured to exacting standards, our tanks are built to withstand Africa’s harshest environments. From desert heat to remote construction sites, the self-bunded design ensures full regulatory compliance from day one.
Available in diesel, petrol, aviation fuel, and multi-product configurations. All tanks ship ready to install with integrated pumps, filtration, and fuel management systems available as complete turnkey packages.
