New water tanks
THE RIGHT TANK, SIZED TO YOUR ROOF AND YOUR RAINFALL
We sell tanks, but we repair them for a living. That is why we size them honestly.
Short answer
What is involved in installing a new water tank?
Sizing to your roof catchment and local rainfall, giving you guidelines to prepare a level compacted pad, then delivering and erecting the tank. Pad preparation is the part most often underestimated. A tank on a poor base will move, and a moving tank leaks.
The work
What we do, and why
When a new tank is the right call
Repair is usually cheaper than replacement, and we will say so when it is. A new tank makes sense when: - The wall sheets are corroded through in several places - A concrete shell has structural cracking that banding cannot hold - The tank is too small for the demand and always has been - The tank is in the wrong place, with too little catchment feeding it - You are consolidating several old tanks into one
If the shell is sound and only the liner or roof has failed, repair it. We would rather line your tank this year than sell you a tank you did not need.
How the tank is specified
Size comes from three numbers: your roof catchment area in square metres, your local annual rainfall, and how much water you actually use. Multiply catchment by rainfall to get what you can collect in a year, then size the tank to bridge your longest dry stretch rather than to hold the whole year.
We also look at the site: ground conditions, truck access, distance from the catchment, and where the overflow can safely discharge. A tank you cannot get a delivery truck to is a tank that costs more to install.
We are an authorised agent for Kingspan tanks, which include the Heritage and Rhino tanks. We are also agents for Coerco poly tanks. Brand choice follows the site and the water use, not the other way around.
How the install is done
You prepare the pad. We give you guidelines to follow, so the pad is level, compacted and free of stones before the tank arrives.
The tank is delivered and erected on the pad. Liner, roof, hatch, leaf basket and anodes are fitted. The plumbing connections are not part of our work. The first fill is done after we leave.
Where an old tank is being replaced, we can take it away first, usually before the new tank goes in.
What drives the cost
The tank itself is priced by the manufacturer and varies by capacity and brand. Our side is delivery and erection. We do not prepare the pad or do the plumbing, so those costs are yours to arrange.
Every job is quoted firm before we start.
How long it takes
Lead time is usually set by the manufacturer, not by us. Allow a few weeks from order for delivery on common sizes, longer for large or non standard tanks.
On site, erection is one to two days for most rural tanks. We give you the pad guidelines and the install date when you accept the quote.
What warranty applies
The tank carries the manufacturer warranty, which is the substantial one, and the terms come from the maker.
The terms are written on the quote before you accept. Manufacturer warranties usually depend on the tank being installed on a compliant base, which is why you get our pad guidelines before the tank arrives.

BRANDS WE REPAIR
and every other steel tank on the market
We repair and re-line steel water tanks from every major Australian brand, plus concrete tanks of any make. The liner is custom made to the correct size for your tank, so the brand on the wall does not limit the repair. Ask about steel tank liners for any of these brands, or about new water tanks if the shell is past repair.

ASKED BEFORE EVERY INSTALL
Still stuck? Call 0499 142 149.
Repair, if the shell is sound and only the liner or roof has failed. Replace when the wall itself is gone. We will tell you which, in writing, before you spend anything.
It depends on your roof catchment, your rainfall and your use. Our sizing guide walks through the arithmetic, or send us your roof area and we will do it with you.
No. Preparing the base is your responsibility, and we give you guidelines to follow. Most manufacturer warranties depend on the tank sitting on a compliant, level, compacted base.
Yes. If it is a replacement or in the same area, we usually take the old tank away before the new one goes in.
