How much should you expect to pay for a rainwater tank? The old adage regarding a piece of string comes to mind for the answer to this question. Here are four main factors which will contribute to the cost of your water tank:

• Water tank size
• Instillation requirements
• What material the water tank is made of
• Delivery

You can purchase a 1000 Litre tank for as little as $300, or for something smaller, Australian Waste Management sell wheelie bins, 120 Litres from $65. Now a days you can order rain water tanks in all shapes and sizes (and costs) but you can pick up a larger tank of 5,000 Litres for as little as $1500. Need something a little larger? A 100,000 Litre tank will cost you around $8000.

Add to this the cost of tank instillation and plumbing by a registered plumber which will vary depending on whether or not you’re going to use your tank water for the toilet and laundry. Typically, a small above ground tank will cost you around $300 to install plus the cost of a pump – starting at around $200.
