Securing a sustainable water supply is essential for business continuity and agricultural success. Rainbow Reservoirs specializes in the manufacture and installation of high-performance steel panel tanks. Our modular designs are engineered to provide robust, long-term storage solutions that can be rapidly deployed across South Africa and the African continent.
Our sectional steel panel tanks are the definitive choice for high-capacity liquid storage, offering a versatile alternative to traditional concrete reservoirs or plastic tanks. By utilizing a "modular" assembly process, we can construct custom storage units ranging from 5,000 litres to over 5 million litres to meet your exact specifications.
Unlike standard tanks, our steel panel tanks are constructed from individual, high-tensile Aluzinc® panels that are bolted together on-site. This specialized design provides several key benefits for industrial and commercial applications:
• Unmatched Corrosion Resistance: Every panel is coated with a high-performance alloy of Aluminium, Zinc, and Silicon, offering up to four times the lifespan of traditional galvanized steel.
• Logistical Flexibility: The "flat-pack" nature of our steel panels allows for easy transport to remote mining sites, rural farms, or restricted-access urban rooftops.
• Cost-Effective Infrastructure: Most steel panel tanks under 350,000 litres do not require an expensive concrete ring-beam foundation, significantly reducing total project costs.
• Future-Proof Scalability: The modular bolted design means your tank can be expanded, dismantled, or even relocated as your water storage requirements evolve.
• Maintenance-Free Operation: Our tanks are designed for a 40-year life expectancy, requiring little to no upkeep over decades of service.
We deliver tailored steel panel tank solutions designed to meet the rigorous standards of various industries:
• Fire Suppression: ASIB-approved steel panel tanks specifically designed for high-volume fire sprinkler and hydrant systems.
• Agricultural Irrigation: Large-scale reservoirs built to withstand extreme UV exposure and maintain water temperature through superior heat reflectivity.
• Mining & Process Water: Rugged, heavy-duty panel systems capable of storing raw water, treated water, or process chemicals in harsh environments.
• Municipal Supply: Reliable backup reservoirs to stabilize water pressure and ensure a continuous supply during municipal maintenance or water-shedding events.

Q: What is a sectional steel panel tank?
A: It is a modular reservoir made of individual steel plates (panels) bolted together. This allows for massive capacities and easier transport compared to one-piece tanks.
Q: Are these tanks suitable for drinking water?
A: Absolutely. Our food-grade internal liners ensure the water never touches the steel, keeping it 100% safe for human consumption and free from metallic taste.
Q: How quickly can a panel tank be installed?
A: Depending on the size, most steel panel tanks can be erected on-site in days, making them far faster to commission than concrete alternatives.
Protect your operations with the most durable steel panel tanks on the market. Rainbow Reservoirs combines Australian-inspired engineering with South African resilience to deliver water storage that lasts a lifetime.
