Capture and transfer rainwater from roof areas not able to be connected to your existing rainwater tank. This compact Aquaplate Steel Colorbond micro transfer tank is complete with an internal high volume water pump which automatically switches on and off to pump rainwater to your main tank through a small 25mm poly pipe which can be hidden either under the house, through roof space or even inside the existing guttering. Can also be used for pumping greywater onto garden areas! |


Harmony Water Tanks is a division of CorroSteel Industries. Our factory is located in Bacchus Marsh just 30 minutes west of Melbourne and we service a wide geographical area including Melbourne City and all surrounding districts, Ballarat and Geelong.
We manufacture a wide range of Slimline and Round Aquaplate® corrugated steel rain water tanks in standard or custom sizes. Our metal water tank sizes range from our pocket sized 500 litre Villa slimline water tank right up to our large 18,000 litre rural round water tank. Although we publish a list of standard tank sizes, we specialize in manufacture of custom sized water tanks with no extra charges. So if you are looking for say a slimline water tank to fit into a particular area, maybe under a window, along a narrow pathway or between two walls, then we can design and make a special metal water tank just for you.
Our Colorbond tanks are attractive to look at and will enhance your property and not give it that cheap plastic look. Our Slimline Water Tanks have nice sleek straight lines, retain that nice lustre of metal Colorbond® and will not crack, bulge or fade as can happen with plastic tanks.
A metal water tank means absolutely no light penetration into the water, with the result of no algae growth inside your tank. We are that serious about this issue that we fit as standard on all our rain water tanks a two piece Light Blocker Inlet fitting on the lid which not only filters the water but also stops sunlight from entering into your tank.
All our rain water tanks are manufactured using BlueScope’s Aquaplate® corrugated steel which carries a 20 year written Aquaplate® warranty against corrosion. Aquaplate coated steel is a 200µm thick polymer food grade material manufactured in accordance with Australian Standard AS 2070 Part 2 “Plastic Materials for Food Contact Use” It is not a polycarbonate and does not contain controversial BPA (Bisphenol A).
Our rain water tanks are strong, fire resistant, come in a wide range of genuine Bluescope colorbond colours or the standard galvanized option. Our tank bases are protected with a Polymer coating and can be placed directly onto either a concrete or a sand base.
At Harmony Water Tanks we offer a total service including water storage system design, free advice, water tank manufacture, water pump and equipment sales and water tank installations.
