Frequently Asked Questions


Who installs my tank?

Check the local codes and current regulations set by your local council. Metroll basic installation guidelines need to be followed and installation should be undertaken by an experienced plumber or tank installer.

How do I work out what size tank I need and how much water can be collected from my roof?

The tank capacity you need depends on your personal requirements, your roof area and annual rainfall in your region. There is a simple formula for working out how much water will be collected from your roof. Approx. 1mm of rain on 1m² of roof equals 1L of water. For example, if your roof is 50m² and the local rainfall is 1200mm then 50 x 1200 = 60,000L of water will be collected per annum.

Assess the area you have to place a tank in and make sure you have assessed the roof catchment area into your tank.

Check your tank to ensure that it has the correct volume and has enough outlets for excess overflow into a stormwater system.

Will I need a pump?

Most tanks operate with a pump. As a general rule a pump is required if water has to be pushed uphill or along ground level.

Does my tank need a stand or base?

Yes. There are 3 main types: reinforced concrete slab, a stand or compacted crusher dust/road base with a surround for support. For further tank information please contact your nearest Metroll office.

Can I get rebate or incentive to install a tank?

This is subject to each State, Council and Shire’s current regulations and must be checked on a case by case basis.

Does it matter where I put my tank?

Metroll recommends that you place your tank in a cool shady place away from trees and falling leaves.

Can I get a warranty?

AQUAPLATE® steel tanks supplied by Metroll carry a 12 month warranty on tank workmanship, commencing from the date of delivery.
