Water storage tank manufacturer expands range What do St Helena, Madagascar, Mauritius and Seychelles have in common? Apart from being islands, they’re all home to Rainbow Tanks.
Q
uinton Coetzee, director of marketing and business operations at Rainbow Reservoirs, explains why: “These islands do not manufacture water tanks. They have to import them. With air freight and sea freight, cargo is charged by volume. A single 10 000 ℓ plastic tank occupies a huge equivalent volume – you are basically paying to ship air. Islands therefore prefer Rainbow Tanks that can be flat-packed and then assembled onsite – the holding capacity of the modular Rainbow Tanks that can fit into a container is much greater, by orders of magnitude, than that of the plastic water tanks.” Used in over 30 countries around the world, like Peru, the Philippines

Where other reservoirs may take months to build, it takes a few days to install our tanks,” says Coetzee. Premium tanks for remote sites Rainbow Reservoirs manufactures its tanks’ walls and roofs from premium aluzinc steel. The aluminium zinc coating is six times more anti-corrosive than a regular galvanised coating. All the tank’s fittings – like roof trusses, nuts, bolts and ladders – are galvanised for durability and long lifespan. “Many tanks have to be installed remotely – in the middle of the Kalahari Desert, on top of a mountain or on a beach – and it’s a huge inconvenience if the nuts do not thread properly or wall panels do not fit perfectly. We therefore have modern, automated machinery that manufactures precision components to ensure everything fits 100% correctly,” adds Coetzee. These premium-quality reservoirs are manufactured in varying sizes – from 5 000 ℓ capacity to over 4 Mℓ capacity – and can be fabricated in any requested
