Choosing a Location for Your Rainwater Tank

Are you looking to purchase a rainwater tank? If you have decided on getting a water tank, you need to know where it will be placed. There exist many attractive styles and colours today to complement your property or a modern home. Once you know how much rainwater you wish to harvest, your next step will be identifying an appropriate location on your property.

Step 1. Understand Council Regulations

Check for council regulations that must be met when installing rainwater tank. For example,

  • most will have setback conditions (minimum distance from your property lines).
  • some might even require your tank to be hidden from view of the street.
  • some may require you to set aside storage capacity for stormwater detention or fire-fighting purposes (if in a bushfire prone area).

These conditions could obviously hinder the type of tank you purchase and/or ideal locations.

Step 2. Pipework Installation Considerations

Walk around the outside of your house and note all locations of downpipes from your roof. While your tank doesn’t need to be right next to a downpipe, choosing a site for your tank that is close to a downpipe will make it easier running the necessary pipework to your tank.

Positioning your tank next to downpipes might also limit your location options. Perhaps your tanks would be better positioned on the outer side of a path, or maybe right up the back of your house in garden surroundings.

If you wish to avoid ugly above ground pipes (a “dry system”), an alternative is to run pipes underground to deliver harvested rainwater into your tank (a “wet system”). Wet systems also allow you to tap into multiple downpipes for greater rainwater harvesting.

Step 3. Plumbing and Pump Considerations

If you will be plumbing your rainwater tank into property so that tank water is accessible from different locations, then it is good to consider where most of your tank water will be used.

For example, if your rainwater will be used in your swimming pool or garden, then locating it near such would be ideal. If you will be plumbing your tank into your house, then it will obviously require much less plumbing work if closer to your house.

Consider also if your property is on a slope, that higher locations are more ideal for a tank. Making use of gravity will mean less pump power is required to push water around your property. If lucky, you might even get away with a gravity-fed system.

Step 4. Match Location Space to Dimensions of Tank/s

Measure the amount of space to ensure the water tank you are interested in buying will fit into the location you’ve selected. Team Poly provide many tank styles and size options that can overcome space constraints such as round tanks, various slimline tank models, under deck and underground tank models. Keep in mind tanks can also be linked together, so if one large tank doesn’t fit then perhaps two or more smaller will do the trick.

Finally, perhaps your tank will fit, but beware that its height doesn’t obstruct windows. Maybe you are considering placing your tank below a high deck. Team Poly sell squat tanks, which have a wider diameter and lower height. Keep in mind you can also dig out and partially bury some of our poly tanks. Refer to our article, Can You Bury Poly Water Tanks in the Ground?

Step 5. Property Aesthetic Considerations

You obviously won’t want your rainwater tank looking out of place or being an eyesore in the location you choose. We believe that the corrugated ribs give a stylish feel to our round tanks, and with the many colours to select from you can ensure your tank matches just about any surrounding.

If that isn’t enough, then there are also many other techniques you can use to help your rainwater tank blend in with its environment. Check out our article, Ideas for Hiding Rainwater Tanks on Properties.
