Why every new home in NSW Australia needs a rainwater tank

Concrete rainwater tanks are a great way to store rainwater from your roof. The stored water can be used for both the home and garden. Due to the great Australian drought personal rainwater tanks were introduced to suburban homes. Water also becomes very important in times of high fire danger for both storage and protection.

Therefore, if you are living in the areas of North and Mid North Coast including the Blue Mountains, Hawkesbury, Southern Highlands, South Coast, Riverine, and Snowy Mountains then you must have a rainwater tank installed in your home.

Water restrictions have often applied during summers due to the low capacity of water flow. As a result, people of North and Mid North Coast have devised other ways to store and obtain water for personal use. This process of saving rainwater is termed rainwater harvesting. Installation of concrete rainwater tanks seems to be the best way to overcome drought and the recent fires.



The best time to install a water tank is when you don’t need it. The tank should be installed at the beginning of the wet season; it ensures that you have as much water as possible during dry seasons encountered through the NSW region.


Water tanks across NSW do not need any approval for installation. However, you still may require building approval. Before 2014, all houses were built to allow the installation of rainwater tanks.

Installation of concrete rainwater tank includes:

  1. Deciding the tank size and capacity according to the need.

  2. Choosing a suitable location for your water tank. The tank should be installed adjacent to the downpipes from the roof, so the rainwater can be stored directly into the tank.

  3. The tank should be positioned on the ground level.
