At Promax we combine inspired design with manufacturing excellence to bring you a range of superior quality rain water tanks and rain harvesting packages that blend perfectly with your surroundings – or put more simply, our tanks look good and work better! They’re fully UV stabilised and the durable one piece construction is backed by a 20 year guarantee.

Promax Engineered Plastics is regarded as an industry innovator and although our construction methods are high-tech, products like Polyflo culverts and fluming and the E1 stormwater system are remarkably easy to work with.

While we’re best known for water tanks and storm water retention systems we manufacture everything from colostrum and molasses tanks to portable diesel and multi-storage units as well as stock troughs, meal feeders, dog carriers and kennels. So whatever you need to store, feed or transport safely there’s a Promax product to suit and with over 300 distributors nationally there’s bound to be a stockist nearby.
