Rain is always welcome in the garden, but can also conserve your resources. In addition, it is so-called "soft" water, in contrast to the often very calciferous water, which can damage water installations such as washing machines.
According to the Federal Office for the Environment, about half of the process water could be replaced by collected rainwater. Thanks to your own use of rainwater, you can water your garden, laundry and toilets.
Usually you will need an above-ground or underground rainwater tank, which is available in various sizes and designs, as well as filters, pumps and pipes as required.
