The smart way to use rainwater: sustainable solutions for watering your garden
Water is an important and often scarce commodity, especially nowadays. Therefore, it is important to handle the precious resource carefully and above all to save drinking water wherever possible. It can be easily replaced by rainwater in certain areas. For example, when it comes to watering plants and gardens, rainwater offers a natural and cost-effective alternative. Especially in dry and hot summer periods, you can't rely on occasional rain showers to properly water your garden. Instead, you can create ways to catch the water, collect it, and then use it to water your plants.
In this blog post, we'll show you different ways to use rainwater, how to collect raindrops, and which pumps will help you get the rainwater where you need it straight away. To do this, you can find sustainable solutions to take care of your home's greenery in a more environmentally friendly way.
Unlike drinking water, the water naturally produced by rain does not have to be treated and therefore does not contain any chemical additives. In addition, rainwater is not mineralised, so it contains less calcium, magnesium and sodium, for example, and contains no limescale, meaning that it is very soft and pure. This makes it ideal for watering and promotes the growth of many plants.
A very common option that can probably be found in most garden is the rain barrel. The advantage of a rain barrel is clear: It can be placed without much preparatory work. Rain barrels are quite cheap, although they will need to be replaced eventually. In addition, you can place several barrels around your home and garden, preferably wherever a rain gutter goes into a downpipe. This allows the water that runs over the roof and is collected in the rain gutter to ultimately make its way into the rain barrel. Incidentally, you can use this principle to catch rainwater on all roof surfaces, provided you install a rain gutter – whether on the roof of your house, your garage or your garden shed. However, caution should be exercised with rain barrels in winter, as freezing water can cause them to burst. So, before the temperatures drop into minus figures, you should make sure to empty the barrel.
Pumps for rain barrels
To use the collected water, you can choose a rain barrel with an integrated tap and fill it into watering cans. If you have a rain barrel without a spout, it is best to use a cordless clear water pump with a flexible gooseneck. This allows you to hang the pump on the barrel and, for example, connect the garden hose to the gooseneck or fill the water above it in watering cans.
Don't want rain barrels visibly on display in your garden, but still want to collect rainwater? Then opt for underground tanks where you can collect the water and even store and use it throughout the winter. Underground tanks also have a larger volume and do not take up any space at all in the garden. The tanks are available in various designs and sizes, from flat tanks to round models, to plastic tanks or masonry tanks. Although the purchase and installation of an underground tank is significantly more expensive than the use of rain barrels, it can pay off, especially with very extensive rainwater use.
If you are looking for a submersible pump for your cistern, you should look for a submersible pump, because this one works with enough pressure to be able to cope with the necessary head from the underground tank to the surface.
Rain gutters as an important supply line
Want your roof and rain gutter to serve as a supply line for your water reservoir? Then you should make sure to clean your gutters regularly so that dirty water is not collected in the rain barrel. To filter the water before it gets there, you can consider installing a pre-filter in the downpipe of your gutter. It's worth remembering that you should clear your gutters of coarse dirt and leaves after autumn and winter anyway. Incidentally, this is very easy with our cordless leaf blower and the gutter set.
Where you can use rainwater
Around the house and garden there are several options for which you can use rainwater. Primarily, you can make garden watering easier, because with the natural and soft rainwater, plants, beds, lawns, vegetable patches and orchards can be optimally watered.
Apart from that, you can also support the domestic water supply with it. To do this you need domestic waterworks. For example, you can then use rainwater to flush the toilet or in the washing machine. But be careful: Depending on where you live, it may be required by law that drinking water and rainwater run in separate piping systems. And the installation of a separate rainwater pipe involves considerable costs. So, think about where you want to use the rainwater and how much you are willing to invest in this.
