Price Comparison

Please note that each price quoted in the Price Comparison below is an estimation generated from a variety of companies throughout Australia and it is a rough guide only. Prices will vary depending on location, company and other factors.

Please also note that most slimline tanks have a maximum capacity of about 5000 to 6000L for a single tank, therefore to reach larger capacities such as 10,000 or 20,000L they need to be joined together.

*Pricing for concrete tanks does not include transport, crane and/or excavation costs for placing tanks underground. This will vary greatly depending on individual circumstances. Expect to pay around $1 per litre once these factors are taken into account, i.e. $20,000 for 20,000L.

**There appear to be limited 'off the shelf' slim line options available for fiberglass tanks. However, there are manufacturers who will make these to order.
