The most useful benefit of a slim line water tank is the narrowness of the tank. Unlike round tanks, which have a larger diameter, slimline water tanks are normally between 550mm and 1000mm. The slim design allows you to get the largest amount of water in the smallest footprint. Slimline Rain WaterTanks in Melbourne are most popular for developers and builders as it allows them to make the most of the space on the land. Smaller slimline tanks are popular as they are more aesthetically pleasing for backyards, or even better they can be put down the blind side of the house and are completely out of the way. On the biggest limitations to slimline tanks is the capacity you can achieve. Typically the most popular is a 2000LT Slimline tank designed for the builder market. However the largest single piece rotomoulded plastic slimline rain water tank we make is the 5000LT Slimline Water Tank. Beyond this size, we do modular tanks, made up of smaller rounded tanks joint in a line to create any capacity needed or joining two slimline water tanks end to end.
