Are Water Tanks Worth It?

Yes, for most Australian households, farms, and businesses, water tanks are worth the investment. You can reduce reliance on the mains supply, get long-term rainwater tank savings, gain a backup during dry periods, and support more sustainable water use across your property.

What Are the Benefits of Installing a Water Tank?

The main benefits of installing a water tank are cost savings, water security, and sustainability. Key benefits include:

• Lower water bills over the long term: Australian households use around 175 kL of water per year on average. According to the Victorian Government, a well-used rainwater tank can save up to 50,000 litres a year, or about 30% of average household water use. Using stored rainwater for toilets, laundry, or garden irrigation directly reduces the amount of mains water you pay for.
• Water security during droughts and restrictions: Having water stored on-site means you can keep essential activities going when there are supply interruptions or local water restrictions. On farms, larger tanks help maintain livestock and horticulture when conditions are dry.
• Environmental sustainability: Reusing rainwater eases pressure on local water infrastructure and helps reduce stormwater runoff, making better use of the rainfall that lands on your roof.

Polymaster rainwater tanks are Australian-made, UV stabilised and food grade, designed as long-lasting poly water tanks that stand up to harsh local conditions and deliver dependable storage year after year.

When Do Water Tanks Add the Most Value?

Water tanks add the most value in areas facing water scarcity, frequent restrictions or higher mains water prices, such as regional and rural communities, fringe suburbs on tank water, and growth areas with pressure on local supplies. They’re also worthwhile on properties with high outdoor use, like homes with established gardens, pools or lawns, and farms that rely on regular water for stock or crops.
