Rainwater: 5 interesting uses


Rainwater is an often overlooked resource nowadays, with the majority of people preferring to use tap or bottled water for tasks requiring water. Using rainwater is environmentally friendly and it is important now more than ever to try to be environmentally friendly with factors like climate change becoming alarming.

Collecting rainwater is relatively easy, as with some simple changes you can divert your roof’s guttering so that it feeds into a water container instead of into drainage. This simple change will mean that every time it rains, you collect a large amount of water ready to use.

You can also simply leave a bucket outside for when it rains if your house does not have ample guttering. It is usually best to use a funnel when collecting rainwater to limit the amount of water that may be lost through evaporation.


One of the best and most common uses of rainwater is using it to water your plants and garden, as most plants will happily accept it. Gardeners will often collect rainwater in water containers for watering their vegetable allotments and greenhouses. They are able to collect and keep a large amount of water close to their plants, allowing for easy access.

Some plants are also picky when it comes to the type of water they prefer. For example, Azaleas don’t tolerate tap water and they need to be watered with either rainwater or tap water that’s been left to dry out a bit.

Washing vehicles

Using processed water to wash vehicles is a huge waste when rainwater can be made readily available and have the same desired effect. You just need to collect it properly and use it as soon as possible, as water that’s been sitting for a while can become less than ideal quickly.

Water for pets

Perhaps it’s not a good idea to give beloved pets rainwater that’s been sitting around to drink – it can become contaminated. However, some animals that we keep around outside all the time can drink it with no issues – like chicken, pigs or cows. It’s still good to make sure the water isn’t stagnant.

Water for ponds and fountains

Filling up garden ponds and fountains takes up a large amount of water is a great way to reduce using litres of processed water unnecessarily. As rainwater is unprocessed, it does not contain chlorine and other chemicals like processed water.

Drinking and Cooking

Even though rainwater is relatively pure, no one can guarantee it will be safe when collecting it through guttering and storing it in water containers and other storage. By using filters and boiling the water, it is possible to drink and cook with it, as this will help remove any bacteria and contaminants.
