Environmental Benefits of Rainwater Harvesting

by Nov 22, 2021Environment, Help & Advice

Rainwater harvesting is the process whereby rain is collected and stored for future use and it is good for the environment for the following reasons:
  • Lessens the impact of wet and dry spells of weather
  • Protects your local watershed
  • Supports your garden to be more resilient
  • Can be used to combat fires
  • Restores your groundwater
  • Reduces your carbon footprint
  • Reduces the need for municipal water infrastructure
Rainwater Harvesting benefits
Aging water infrastructure is expensive to replace, maintain and implement. The more water that each person harvests, the less dependence there is on municipal water infrastructure. This also helps with drought-proofing the surrounding areas and having local water on hand to deal with bushfires.

Experts tell us that in the natural landscape, approximately 50% of storm water infiltrates into the ground, hydrating the soils and recharging groundwater, about 40% evaporates and 10% runs off. In contrast, in developed landscapes, 15% infiltrates the ground, 30% evaporates and 55% runs off all the hard surfaces such as roads and building materials.

When you install water tanks you reduce the impact of stormwater by holding the water on-site rather than letting it run off. This means you store the water and use it at another time when it is most needed and when it is more likely to infiltrate into the ground and make it more nutritious and productive.

Rainwater Harvesting Benefits
Plants love rainwater above ‘town’ water because it is free of the salts, chemicals and minerals found in other water sources. The pH balance and nitrate delivery levels are perfect for uptake by your healthy plants. Keeping the world green has a direct impact on the whole water cycle, ecosystems.

When the rainwater infiltrates your ground, it is filtered naturally by the earth and is prevented from entering storm drains as polluted run-off. This also reduces the chances of heavy erosion occurring from the build up of fast, strong-flowing, run-off water.

Experts tell us that the cost of storing, treating and transporting municipal-based water accounts for over 20% of per-capita energy use. When you reduce your reliance on pumped and treated water you are also contributing to a collective saving in energy at the same time.

Future climate change will impact on the water savings and performances and all these strategies and designed rainwater water systems but effective water harvesting and usage will significantly diminish the effects of this climate change and bring both direct and indirect benefits to the environment.
