How to Determine Required Size of Aussie Rainwater Tanks

Water From Clark TanksIf you are an Aussie relying completely on the state-provided water supply, you are pitting yourself against the country’s robust freshwater vagaries. Installing water tanks in your house is vital, perhaps even more important than installing burglar alarms but how do you determine the size of the rainwater tank that your house would need? Here is a quick size guide for rainwater tanks in Australia.

Average Rainfall

The best starting point for calculating the size of the Aussie water tanks needed is the average rainfall data for your area. Remember that our country’s rainfall varies wildly from year and year and you must obtain data including the average rainfall and probable dry spells from a reliable source like the Bureau of Meteorology.

Your Household’s Water Consumption

Next, approximate the volume of water your household will require from your water storage tank. Count the number of members, average water consumption per person and outline all activities where water from the tank will be used. This number can run into tens of thousands of liters in bigger households.

Roof Catchment Area

This is the area that will collect rain water and empty it into the tank. Calculate total rainwater catching area including all roofs, slopes and eaves. This value will be less than 150 square meters for smaller houses and greater than 200 square meters for larger ones.

The size of your tank will depend on the average rainfall, catchment area and required volume. In addition to these, a fourth factor may be laid out as the security of supply that is the probability of a reservoir meeting all of the household’s demands. Households in areas with greater average rainfall, consumption, catchment areas and need for security will require larger Aussie water tanks.

Lastly, many local governments in most states provide pre-calculated ranges of Aussie water tank sizes based on the area’s average rainfall and house specifications. Make sure to check with your local weather bureau before determining your tank’s size.

Don’t Look Past Poly Rainwater Tanks!

When it comes to the materials used in the making of rainwater tanks, you can access products made from different quality concrete, steel, fiberglass and plastics. Among the various materials types, food-grade poly water tanks stand unique because of their various benefits.

If you are planning to have a water tank installed in your home and are not sure of the materials used for its construction, you should consider high-quality polyethylene rainwater tanks. Let’s explore some details about poly water tanks.

What Are Poly Rainwater Tanks?

These are tanks built to store rainwater that are constructed from a wide range of plastics. Common among these are the Polyethylene, Polyvinyl Chloride (PVC) and Polyvinylidene fluoride (PVDF). Polyethylene is commonly used for most of these tanks as it is chemically-resistant and light thermoplastic using different forms of plastic resins.

Poly water tanks are built in different sizes, shapes and can hold various forms of water capacity. High-quality poly tanks are built with seamless construction which provides them with great strength.

Why you should choose plastic rainwater tanks

There are several reasons you should prefer installing rainwater tanks over other types. Some of these are highlighted below:

  • They are cheaper or affordable than steel tanks. Hence, they are more economical.
  • They are simple and easy to install whether you are having them above ground or underground
  • They don’t corrode nor rust, hence they don’t leak easily because of their feature of superior resistance to corrosion.
  • They are easy to clean and maintain
  • They are offer users the opportunities to choose from wide range of shapes, sizes, and colors that will blend with the architecture or design of the home.

So, plastic rainwater tanks offer very many advantages to users and many prefer them to the traditional galvanized steel water tanks.

Finally, you can use plastic rainwater tanks to store rainwater you can use for watering your garden, doing home washing, flushing the toilets, or serving as drinking water. Many brands of plastic rainwater tanks are sold in the market place. You just need to review and compare offers from different leaders in the industry before selecting the most suitable one. Three Australian poly tank manufacturers I recommend checking out are Clark Tanks, National Poly Industries and Team Poly.
