Il existe de nombreuses raisons pour lesquelles les gens choisissent d'utiliser l'eau de pluie autour de leur maison et même pour la boire.  

En fait, la réalité est que l'utilisation de l'eau de pluie peut apporter d'importants avantages économiques, sociaux et environnementaux.   

Vous trouverez ci-dessous quelques raisons pour lesquelles les gens choisissent d'utiliser l'eau de pluie - et le avantages que ce choix apporte.

Réduire la dépendance à l'eau de ville

By using a Rain Harvesting system to supply water for some or all of your requirements, you can reduce your dependence on mains water. In turn, this will reduce your water bills and save you money. It will also ensure you’re less affected by any water restrictions that are put in place due to drought or the need to protect community water supplies from overuse.

It’s not just individuals who can save money by reducing their dependence on mains water, either. The cost of supplying mains water to the community continues to increase. The construction and maintenance of dams, pipes and treatment plants is huge, and tax and rate payers foot the bill. The less people are reliant upon these systems, the less they will need to be expanded.


Mains water is not available in many rural or low population density areas. In these areas, the most obvious benefit of Rain Harvesting is to have a supply of water to sustain life and meet your other needs.

It may also be necessary to use rainwater as a backup or supplement for other water supplies, such as a bore or dam on your property, or to ensure you have a store of water available to fight bushfires.

Économiser de l'argent ou bénéficier de remises

Using rainwater can bring many economic benefits. Rain Harvesting can help you save money on your water bills and store water in an economic way. In some areas, local councils have introduced cash-back rebate plans for those who install a rainwater tank.

Règlement de réunion

In some suburbs and states, government have introduced legislation and regulations mandating the installation of rainwater tanks for new homes or setting new standards for energy and water efficiency that new dwellings need to meet.

Santé et préférences personnelles

Certaines personnes préfèrent utiliser l'eau de pluie pour des raisons de santé ou de préférence personnelle. Par exemple, certaines personnes préfèrent boire de l'eau douce sans les produits chimiques ajoutés qui sont utilisés pour traiter l'eau du réseau.

Others live in areas where the mains water is salty, “hard”, contains heavy metals or has an unpleasant odour, making rainwater an attractive alternative.

Environmental Considerations

Rain Harvesting and the use of rainwater around your property can also bring benefits for the environment. By harvesing the rainwater that lands on your roof, you can reduce the impact of stormwater runoff in your area, which can otherwise damage creeks and other water habitats. Rainwater is also good for the garden – after all, it’s what your garden is naturally watered with.
