Rainwater Harvesting: Choosing and Installing the Correct Water Tank
Everyone knows that a rainy day can help your garden and even provide you with some rest and relaxation, but what some people don't realise is it can also help reduce your water bills and help you should water use be restricted by local government during times of drought. Unfortunately, you only get these benefits if you have a rainwater tank installed.
If you are considering installing a rainwater tank, we have created a quick guide that will help you determine what type of water tank you should have installed.
Consider How You Plan on Using the Water
Rainwater tanks can be installed for indoor and outdoor use or just outdoor use. Think about how you plan on using the water that you collect. Will you be using it for your gardens? Do you want to use it indoors? With a correctly plumbed diversion system in place, your tank water can even be used to flush your toilets, saving you having to use town water.
If you wish to use the water from your tank indoors, for the washing machine or toilets, then you will require the services of a licensed plumber in Melbourne. Yourself or the company that supplied them, as the installation can be relatively easy and straightforward, can often just install outdoor water tanks.
Household Size Determines the Size of the Tank You Will Need
Larger households will use more water on a daily basis than smaller households. It is important to factor in how many people live in the house and how much water will be used. More people typically require larger water tanks.
Think about House Structure and Location
The number of people in your home isn't the only factor you need to consider. You also need to think about the size of your roof and how much rain falls in your area. If you have a smaller roof, it will take longer to collect water. This doesn't mean you can't have a rainwater tank, it just means you may want to opt for a smaller one. As a general rule, the roof on a single story house is often larger than the footprint of the home and you can use a rough guide to calculate the catchment area of it:
1mm of rain = 1 litre of water per m2 of roof area. (Allow 10-15% for wastage)
The same can be said for rainfall. Areas where the annual rainfall is less will often find it difficult to collect enough rainwater to meet demand.
Consider Where You Want to Store the Water Tank
Rainwater tanks come in many different shapes and sizes. This gives you the opportunity to choose a convenient place to have the water tank stored.
Some options you may have available to you include:
- Round, metal squat water tank – often placed under decks
- Slimline water tank – fits in narrow spaces or along fence lines
- Underfloor water tank or a bladder storage system – larger, out of sight storage
Budget, layout of the home, how you will use the water, and local regulations will all determine what type of rainwater tank you choose to have installed.
