In an era of increasing water scarcity and "water-shedding," securing a reliable, high-capacity storage solution is critical. Rainbow Reservoirs provides world-class steel water tanks engineered specifically for the demanding African climate.
From 5,000-litre domestic backup units to massive 5-million-litre industrial reservoirs, our sectional steel tanks offer unmatched structural integrity, longevity, and cost-effectiveness.
When comparing liquid storage options, steel stands out for its durability and scale. Unlike plastic tanks that can become brittle under UV exposure, or standard galvanized tanks that may succumb to corrosion, our tanks utilize advanced Aluzinc® technology—a high-performance alloy of 55% Aluminium, 43.4% Zinc, and 1.6% Silicon.
• 40-Year Lifespan: Engineered to last decades with minimal maintenance.
• Corrosion Resistance: Our Aluzinc coating provides up to four times the protection of traditional galvanizing.
• Potable Water Quality: Every tank is fitted with a heavy-duty, food-grade internal liner, ensuring stored water never touches the steel walls.
• Modular Design: Delivered "flat-packed" for easy transport to remote mining sites or urban rooftops.
• Rapid Installation: Our expert teams can assemble a high-capacity reservoir in a fraction of the time required for concrete alternatives.
We provide specialized steel water tank solutions across several key sectors:
• Fire Protection: Fully ASIB-compliant tanks designed for high-pressure sprinkler and hydrant systems.
• Mining & Industrial: Rugged storage for process water, dust suppression, and chemical containment.
• Agriculture: High-volume reservoirs for irrigation and livestock that withstand the harshest rural conditions.
• Commercial & Residential: Essential backup water systems for shopping centers, hospitals, and housing estates to ensure business continuity during municipal outages.

Q: How long does a steel water tank last?
A: Our steel reservoirs have a predicted service life of over 40 years, making them one of the most sustainable investments in water infrastructure.
Q: Can these tanks be moved?
A: Yes. Because our tanks are sectional and bolted, they can be disassembled and relocated to a different site if your operational needs change.
Q: Do I need a concrete foundation?
A: For many tanks under 350,000 litres, a well-compacted sand or ring-beam base is sufficient, significantly reducing your civil engineering costs.
Don’t let infrastructure failures interrupt your operations. Join hundreds of businesses across Africa that trust Rainbow Reservoirs for their liquid storage needs.
