A rain barrel is an important part of sustainable garden maintenance. Not only do you save costs by pouring the collected rainwater for flowers or using it for the household, you also protect the environment at the same time. It's only annoying if you can't make full use of the precipitation because your water butt overflows when it rains too much. On this page you can find out what options there are to prevent this loss.

If a rain barrel overflows, a second one is needed

Adjust the volume

Even before you buy, you should consider the volume of the rain barrel that is appropriate for your consumption. In principle, the more lawn you have, the larger your water butt should be.
Two factors play a role in the precise calculation:

  • The amount of rain that flows from the roof
  • your water needs

The required capacity of your water butt results from the ratio of these components.

Calculate amount of rainwater harvested

According to statistics, a 25 square meter roof supplies 1000 liters of water annually. Of course, neither you nor experts can determine the tow exactly. After all, the rate of precipitation can never be accurately predicted. However, if you use this guideline as a guide, you are on the safe side.
In addition, however, there is evaporation due to solar radiation. It is therefore advisable to set up the rain barrel in a sheltered place. You should also pay attention to an existing cover when buying.

Calculate your own water needs

To determine your water needs, use the following components as a guide:

  • The climatic conditions of your place of residence
  • The size of your garden
  • The individual water requirements of your plants

To give a statistically determined value again, there are around 60 liters per square meter per year. The best way to read your actual water consumption is from your water meter.

prevent overflow

  • Install an overflow protection
  • Connect two rain barrels (€53.99) together
