NO CONCRETE WORKS ARE REQUIRED for Oasis Tanks under 350,000 litres. Tanks in excess of 350,000 litres require only a simple concrete ring beam upon which the tank is installed.
Engineered by Rainbow Reservoirs, Oasis Tanks provides world-class steel water tanks designed for longevity, reliability, and total water security. Our solutions are built to withstand the harshest environments while maintaining the highest standards of liquid storage.
When it comes to bulk water storage, steel water tanks offer a structural integrity that plastic alternatives simply cannot match. Our tanks are built using high-tensile AZ150 structural steel plate, ensuring a lifespan of up to 40 years. This advanced alloy coating provides significantly better protection than standard galvanizing.
Every tank is engineered to be a permanent asset for your property, whether you are managing a commercial farm or a large industrial facility. The modular nature of our steel panels allows for high-capacity storage without the logistical nightmares of transporting pre-built structures.

Reliable irrigation and livestock watering are the backbone of farming. Our steel tanks provide the volume necessary to survive drought periods and manage borehole output effectively. We understand the South African climate and build tanks that can handle the heat and the wind.
Our large-scale reservoirs provide high-pressure water storage for warehouses, mines, and factories. These tanks are designed to meet heavy-duty requirements, ensuring that your facility has a dependable supply for both operations and emergency safety protocols.
Take control of your home water supply. A steel tank offers a sleek, aesthetically pleasing backup solution for urban and rural households alike. By harvesting rainwater, you reduce reliance on municipal systems and ensure your garden and home remain functional year-round.
We understand that many sites are remote and difficult to access. Our steel water tanks are shipped in flatpack kit form, drastically reducing transport costs and allowing for delivery to almost any location. Our expert teams can install most medium-sized tanks within a matter of days, often without the need for complex concrete foundations for smaller models.
This efficiency does not come at the cost of quality. Every bolt, seal, and panel is checked to ensure that the finished reservoir meets our rigorous internal standards before we hand it over to you.
