Tank Details and Inclusions

Tank Details and Inclusions

More about this tank: The R1800sq is a unique little tank with almost 2,000 litres of water storage capacity. This rainwater tank has a nominal height of only 1220mm and an inlet height of 1170mm. This should make it easy to get water into, as inlet height should never be an issue, even for a small garden sheds for example. It’s squat design also means that it would make the perfect header tank, whether it be placed on a tank stand, or on higher ground. Using this as a header tank would allow you to connect it to a larger water source (for example a large tank that is connected to your home on lower ground and a pump), and then benefit from gravity fed water from the header tank to a lower level.


While this is a smaller water tank offering just shy of 2,000 litres of storage capacity, it can be extremely useful. For example, offering up to approximately 360 single toilet flushes. Or perhaps offering 450 hours use of a traditional garden dripper. Its squat design is one of the main factors that make this tank unique, allowing it to be used as a header tank where many other tanks may not be suitable. Or perhaps connecting it a smaller building or placed in a position where you need your rainwater inlet to be lower (to gravity feed into the tank inlet). You can also choose from over 20 stylish tank colours, and select your outlet and overflow locations to keep your plumbing neat and tidy. If you want a great little tank with a squat design, this is an excellent choice! If you’re looking for something a little bigger, you may also like to consider the R2720 with over 2,500 litres of water storage, or perhaps even our R 3000 litre model.
