Building a new home – what size water tank will suit your needs?


If you are building a new home you can easily overlook things like the storage capacity of the rainwater tank that is planned for your new home.

At the time of planning a new home most of us think of a rainwater tank as something that we just have to include to comply with BASIX regulations. Since the introduction of BASIX in NSW, new homes are now being designed to use less energy and less water consumption.  We often forget about the real advantages of having a water tank installed when planning our new home because there are so many other things to consider. Given that you will be living in your new home for many years to come it’s worth taking the extra time to consider these things at the time of planning your new home to avoid disappointment later.

The plumbing design in most new homes these days is set up to allow you to store rainwater from your roof catchment area to use for laundry washing, outdoor taps & flushing toilets. Most homeowners that have a water tank installed for these purposes find that their water usage is reduced by 50% or more. Of course it also helps to have water saving shower heads installed in each bathroom which most builders would offer as a standard inclusion these days. new-home-tank

The ideal tank size for a new home will depend on what the home owner intends to use the stored water for.  For instance, if you are considering installing a pool at your new home you can use the tank water to top up the water level during warmer months. Keen gardeners who like to have a green lawn & garden all year round will also need to factor this in to ensure that the tank will suit their needs.

Water tanks come in a range of different sizes & shapes. Aquaplate Bluescope Steel water tanks can be custom made locally in the Hunter Region to suit your requirements or you could choose from a poly tank as both come in a range of popular colours to compliment the style of your home.

On a standard sized suburban block of land it can sometimes be tricky to find the right location to install the tank. There are slimline tanks available that can be positioned down the side of your home to avoid the need to have a large round water tank taking up a significant portion of your backyard.

Before you sign off on your new home plans, do your homework and talk to your builder when planning your new home to ensure that you find the right water storage solution to suit your individual needs.  If you are using a project home builder you may find that they do not offer the tank size or shape that you are after due to constraints from their supplier.  If this is the case it’s worth talking to them about the possibility of you sourcing the tank yourself elsewhere.

The cost to upgrade the tank to a larger capacity upfront will be insignificant when you consider the long term benefits such as the reduction in water usage bills over the coming years.

If you require further information talk to your local council and/or a professional rainwater tank retailer for more detailed information about the design and installation requirements of rainwater tanks in your area.

    Water storage is so important. Having a water supply can really make a difference in a crisis. I have actually never thought about having one including in the home building plans though! That is an incredible idea!
