Water Tanks


Water harvesting is the collection of water for re-use around your home or business. Collecting rainwater to use on gardens, fill pools, wash cars or to flush toilets is an example of both water conservation and business efficiencies.
You will need to ensure that any product or equipment installed is compliant with Australian Standards and other relevant local council regulations.

The National Rainwater and Greywater Initiative offers household rebates of up to $500 for new rainwater tanks or greywater systems purchased after 30 January 2009. Applications for rebates will only be accepted from 1 March 2009.


Nature Coast Plumbing can supply and install prefabricated underground concrete water tanks to suit your needs. the prefabricated solution typically suits smaller excavation areas.

Concrete rainwater tanks are a good alternate to poly rainwater tanks and steel rainwater tanks in areas with a high risk of bush fire damage.

Concrete rainwater tanks either come pre-fabricated or are formed and poured on site.

Concrete rainwater tanks can be used for above ground, in ground, retaining walls and under slabs in new building construction.


Poly rainwater tanks have become the most popular rainwater storage tanks sold in Australia today. The move towards poly rainwater tanks has been due to several contributing factors. The main reasons for the increased popularity for the poly rainwater tanks are their inherent resistance to corrosion and resulting longer life.

Poly rainwater tanks are available in a large range of sizes, shapes and capacity, ranging from small tanks holding 100 litres to poly water tanks greater with capacities of up to 45,000 litres.

Slimline Tanks Traditional corrugated and modern flat sided designs. Ideal for side paths or areas with narrow access. Available sizes of 500 – 2,500 litres. Tanks can be linked to achieve greater storage capacity.
Round Poly Water Tanks Traditional round tank design for small to large scale water harvesting. Tanks can be installed on a crusher dust or reinforced concrete slab. Available sizes of 500 – 27,000 litres.
Large Round Poly Water Tanks Designed for high volume water harvesting with capacities ranging from 35,000 to 50,000 litres.


The tank(s) must have a minimum 2,000 litre capacity and be purchased in full and installed between 1 July 2007 and 30 June 2011 inclusive.
Households not connected to the mains supply are eligible for a rebate for the purchase of the tank only.

Rainwater tanks installed to comply with BASIX (the Building Sustainability Index) for new homes, major renovations or a pool installation are not eligible for a rebate.

From 15 January 2010, the total NSW Home Saver Rebates a household can receive must not exceed $1500 per property.
