Precast/Delivered to Site

Delivered to Site in ground concrete tank (Precast Concrete Tanks)

Panthers Concrete Tanks construct high quality water storage solutions on a variety of residential block types, from smaller tanks on suburban blocks with limited space to large concrete tanks on spacious rural properties.

A residential concrete rainwater tank is a perfect investment to supplement your existing water supply or should town water supply not be available, as a total water storage solution for your property.

Concrete Water Tanks can be constructed anywhere on your property where there is truck access. 

Tanks can be constructed below your current ground level and buried with soil once complete. This allows grass to grow over the top resulting in no tank showing, allowing all the benefits of a water tank without the loss of precious backyard space.

We have a number of standard tank sizes available.

Underground tanks are fitted with a manhole and riser to ground level for easy access

(Davey Pump and RainBank Concrete Tank System)

The automatic tank and mains water controller for your home

The Rainbank system is a small unit that can be installed between the tank and the mains water supply.

Automatically switches between rainwater and mains water supply.

There is no re-pumping of mains water supply.

Provides seamless mains backup in the event of no rainwater or electrical interruptions, for convenience and comfort.

How the system works

  • The Rainbank uses tank rainwater as the main source for the outlets such as toilet, laundry and garden taps.
  • When there is no tank water it automatically and seamlessly selects mains water supply.
  • When it rains and the tank refills the Rainbank automaticallyand seamlessly changes back to tank water supply.
  • The Rainbank automatically switches between rainwater and mains water supply with lights on top indicating which one is in use.


Panthers Concrete Tanks, delivered to site are a high quality, cost effective, tank system that can be built for any situation.

They are low maintenance, strong, store cool, clean water and last a lifetime.

Davey Pump and Rainbank Concrete Tank System

The Rainbank is a dual source controller, specifically designed to souce rainwater for water applications such as toilets and laundry, with automatic mains backup. It is to be installed between the water tank and mains water supply. When the tank has rainwater in it the Rainbank will automatically select the tank water and when there is no water in the tank the Rainbank will seamlessly switch to mains supply.



The tank will be lifted into excavated site. Appropriate access must be provided for the crane truck to lower tank to site. Any additional crane hire not included.

Please refer to the tank sizes page for information on the hole diameter for excavation
