rain barrels

If you do not own a garden, you usually do not like it when it rains outside. Hobby gardeners, however, are usually happy about it. Why? Quite simply: on the one hand, the plants are poured in the garden, on the other hand, the rainwater can be collected and later used as irrigation water. This in turn has the advantage that water consumption can be reduced enormously and so much money can be saved.

Just think: how many liters of tap water do you need to use to irrigate your entire garden? A lot or? So that's also a lot of money. And in times when the cost of water and wastewater tends to go up, it can be a big hit on the wallet. But not only that. Rainwater is much better for plants than tap water anyway (Reading tip: Pour outdoor plants with tap water - you should be aware of that). So just use the free good that falls from the sky to water. All you just need is a collection container.

This is how rainwater can be collected and stored

➤ Option 1 - Place the rain barrel:

Probably the easiest and cheapest way to collect and store rainwater is to set up a rain barrel. It is most effective if you place the rain barrel under a downpipe that directs the water from the roof directly into the bin. So you have enough irrigation water for a smaller garden in no time.

In general, commercially available plastic containers are offered as rain collection containers, which have a volume of 200 to 500 liters. Those who are too rustic, can also rely on very modern and cool rain barrels. In the trade you can find next to wooden barrels, column tanks, rain barrels in the form of amphorae and with planters for almost every garden style or taste exactly what you need.


A particularly beautiful rain barrel in the shape of an amphora you can, for example. on It has a volume of 200 liters and is really a very nice alternative to the conventional rain barrel. And the great thing about this model: the integrated planter also makes it possible to create a very individual design.

➤ Option 2 - Set up the water tank:

For larger gardens, where 500 liters are simply not enough for pouring, the installation of several rain barrels in different corners of the garden is recommended. Alternatively, you can also put a large water tank with 1,000 liter capacity in the garden.

The only problem: these tanks usually do not look very nice. For those who do not mind the look or who can hide the tank in a corner in the garden, such a water tank is perfect. And if you're creative, then you can make a disguise for it, so that the tank visually matches the style of the garden.


A simple option would be, for example, the cladding with wood. For instructions, see Here you can see not only what the wood paneling looks like, but also what you need in terms of material and tools.

➤ Option 3 - Integrate cistern in the garden:


If you do not want to put a rain barrel or a water tank in the garden and also want to be as independent as possible from the public water supply, you can also integrate a cistern in the garden. It is an underground or covered rainwater collection tank, which usually has a capacity of 3,000 to 10,000 liters! With such a cistern, you really do not need to use tap water anymore for pouring.

The great thing about it: because cisterns are embedded in the earth, they take no place and can be used, for example. even be installed under a garage entrance. But not only that. In a cistern, you can also collect rainwater for household use and, for example, for using the toilet flush or the washing machine.


What such models look like or what models there are, you can, for example, to look at Here you will find both plastic cisterns and concrete cisterns. You can also get advice about which option is better for your garden.
