Rainwater Tank Benefits of Linking Two or More Water Tanks

Rainwater Tank Benefits of Linking Two or More Water Tanks Calculating how much water you use or the amount of rainwater harvestable from your rooftop provides a reasonable estimate of what rainwater tank size you need. Instead of investing in one rainwater tank, did you know there are advantages with installing two or more tanks? This is especially true of poly water tanks.

Better Price on Multiple Poly Water Tanks

One benefit when purchasing two or more of the same poly tank is that it can be cheaper than buying one large tank. This is especially true if you select two or more of a popular water tank model. Take for example, National Poly’s 5000 gallon tank offered in Queensland, or the 5400 gallon tank sold in New South Wales. These water tanks are some of the more popular models that consumers purchase. Since they are manufactured on a daily basis, this results in less preparation work in the manufacturing process to roll off another tank in this size. The lower overhead means better deals can be provided on certain sizes. It can even be cheaper to buy a larger sized tank for this reason. Now apply this principle to your own rainwater tank purchase. If we can roll off two or more tanks using a mould already prepared and mounted, then there is less work involved to manufacture two or more of the same tank than tanks in differing sizes. Less works means it is more cost-effective for us to produce. So purchasing two or more poly tanks can sometimes benefit your hip pocket, saving you money.

Reduced Water Loss in Tank Failure or Water Contamination

Ever thought about what would happen to all your rainwater if your water tank failed? Having more than one tank can reduce the loss of water and help alleviate some of the stress experienced if such ever happens. Consider what will happen to all your stored rainwater if your tank became damaged and needs to be replaced? What about all the rainwater you could collect while waiting for a replacement tank? Splitting your storage between two or more tanks is obviously more beneficial in such situations. Your second tank acts like a backup which can provide you with ongoing rainwater storage should you ever have a problem with one. Obviously, a multiple tank setup would be crucially important in rural areas where access to a mains water supply isn’t possible. It is important for you to not miss out on collecting any rainwater that falls. This makes a multiple tank setup the most practical solution if you depend upon your own water sources.

Multiple Water Tanks Provide a Flexible Storage Solution

Linking two or more tanks makes it easier to add or remove tanks to suit your water usage needs. Although rainwater flow, piping and water diverters need to be taken into consideration, it is often easier and less expensive to add another rainwater tank to an existing system than to replace an existing tank with a larger one.

Smaller Tanks Can Use Property Space More Efficiently

Upon first consideration, you might think having a single large tank will consume less space than two or more smaller tanks. It seems like more space would be needed to spread out several tanks than a single large tank with the same storage capacity. If you have more awkward and narrower spaces however, then multiple smaller tanks could make better use of such space. Smaller tanks are also easier to hide and often easier to fit in with landscaping or behind other structures. While many tanks we sell are aesthetically pleasing with ribs and the like, some local councils have rules about not having unsightly big tanks visible from the street. Several smaller tanks might help you satisfy any such requirements.

Installation Considerations of Multiple Tanks

It is true that setting up a multiple tank system is a bit more complex, but then the flexibility and benefits such can provide you with may outweigh any such hassle. Consider that a licensed plumber is often required to install your water tank anyhow, especially if connecting a rainwater to mains water switch. All licensed plumbers experienced with rainwater tanks should know how to plan out and connect two or more tanks.
