We provide a complete supply, fitting and rain water tank installation service. In saying this, we are not licensed plumbers or electricians so you will need to contact an external tradesperson to connect the hoses and power to your tank.

Selecting the right size and type of tank is just part of the purchase decision. We ensure the whole rainwater tank system meets your needs and delivers an efficient and reliable source of water.

Where Can I Place My Tank?

When it’s time to choose where to place your tank, we will assist you to assess five key considerations:

  • Maximising the tank’s catchment area
  • Providing a safe and stable foundation as the tank will be large and heavy once it’s full of water ELSE we can install an underground foundation
  • Contact Dial Before You Dig on your behalf
  • Assist with Council regulation paperwork
  • Truck or crane access considerations for hassle-free delivery

Connection Of The Tank

We recommend that you hire a licensed plumber who’s experienced with rain water tank installation.  Your tank will need plumbing connections to deliver water from your:

  • downpipes to your tank
  • tank (when it’s overflowing) to the stormwater system
  • tank to your pump
  • pump to your garden taps, toilets, washing machine, hot water system and/or household plumbing.

You may also need an electrician to provide a safe power supply for your pump and auto-switching device.

Your plumber will need to book and pay for an inspection from NSW Fair Trading for any water tank installations:

  • that are connected to a toilet, washing machine or hot water system
  • where the tank is topped up by, or switched to, the drinking water supply when it is empty.

Don’t forget to ask your plumber for your Certificate of Compliance when the work is done.

Water Tank Installation

To do its job well and deliver clean, clear water, your new tank will need to be properly connected.

  • Check your roof and guttering are suitable for collecting rainwater. Do not collect rainwater from roofs with lead-based paint or flashing, bitumen based products or with exposed, treated wood.
  • Prevent blockages from overhead trees by installing gutter guards.
  • Prevent insects (and any other animals) from entering your tank. Your rainwater tank inlet and overflow must be mosquito proof and you must ensure there’s no other point of entry.
  • Use a first-flush device. This is a simple and effective way of only letting the cleanest water into your tank.
  • Install a fail-safe, top-up water connection or an auto-switching device to supply drinking water when the tank is empty.
  • Add energy efficient accessories like a pressure tank to your pump. These reduce the number of times your pump runs, saving energy and maximising the pump’s life.
  • Consider how you will use your rainwater before buying a water filter. Many filters are not suited for rainwater as they clog quickly and dramatically increase your pump’s energy use.

Your Local council regulations

Rainwater tanks are large, very heavy when full and can cause harm if they aren’t installed or maintained correctly. A number of regulations are in place to help make sure your tank is safe and suitable.

  • Contact your local council to see if they have any local requirements you need to comply with.
  • Tanks that can store a maximum of 10,000 litres of water don’t normally need council approval. However, there are a number of conditions that you must comply with

Do some research and see what best suits your needs and budget before you make your decision.

What you need to decide What to consider
Tank size Try to work out which tank size will deliver the greatest savings for your home. There are a number of websites and apps that can help you find the right tank size. You’ll also need to consider your budget and how much space you have.
Tank type Tanks come in a wide variety of sizes, shapes and colours. You may also consider a below-ground tank, though these are much more expensive to buy and install. Where you can locate your tank will influence the type of tank you can use.
Pump type Most tanks need a pump to supply water at the same pressure as your drinking water supply. There’s a wide choice available. A little research can help make sure your rainwater supply does not use more energy than necessary. When you choose a pump and where it will be located, ask about the noise it makes when running. A submersible pump is a common choice, but they can be big energy users.
Installation options In addition to choosing the location of your new tank, you need to consider how it connects to your home’s downpipes and then to the stormwater pipes. Maximising the roof area flowing to your tank is the best way to maximise your water savings, regardless of your tank size.
Price If price is a limiting factor, consider a minimum tank size of 2,000 litres. Make sure you can afford to have it connected to at least one regularly used internal plumbing fixture like a toilet or washing machine and to as much of your roof as possible. This will help you receive maximum value.
