Water is a liquid that is used every day in everyday life. Water can be liquid, solid or gaseous and fulfills very different purposes. Most of the drinking water used in the household is used for cleaning, personal hygiene and toilet flushing. It is used, for example, when showering, cooking, drinking, doing laundry or cleaning. Only small amounts are used by people for drinking and food preparation. In Germany, the daily per capita consumption of drinking water (as of 2019) is around 125 liters of water. Interesting: Just under 30 years ago, an inhabitant in Germany consumed an average of around 147 liters of water a day. Due to a global water shortage, however, water is a precious resource that deserves protection. Water-saving gadgets can help to save water in everyday life and use it more consciously.
Whether for brushing your teeth, taking a shower, washing your hands or flushing the toilet – water is often used in the wet room. This is a good way to save water in the bathroom.
Conventional shower heads use an average of 12 to 15 liters per minute. So if you shower for ten minutes, you use around 150 liters of water. A water-saving shower head should help. You screw the shower head to your shower hose as usual. The trick is that the shower head lets less water through, but still keeps the water pressure constant. This is possible with this water-saving shower head, for example, by adding air to the water, creating water bubbles filled with oxygen.
This trick is simple but effective: Do you sometimes leave the water running while you're brushing your teeth or soaping your hands, lost in thought? A comprehensible action, this is the most convenient. In fact, by turning off the water supply while cleaning or soaping, you can save water quickly and easily.
A water stopper helps to effectively implement tip 2, because a water stop shuts off the water supply with one click. This is particularly useful for those who have a two-handle faucet installed on the washbasin or shower. The gadget is therefore suitable for the shower and sink. While lathering up, you can temporarily slow down the water and effectively save water. A practical side effect: the set temperature, which has to be set individually with a two-handle faucet, remains the same thanks to the water stop.
Cooking, doing the dishes or washing your hands – water is also regularly needed in the kitchen. So it's worth taking a closer look at kitchen rituals to save water.
Two-handle faucets consist of a controller for warm and one for cold water. The adjustment requires that some water must first run through until the temperature is comfortable and suitable. A single-lever mixer replaces two controllers with one and the ideal temperature can be regulated more quickly. The result: water is saved and handling will be easier in the future.
In the garden you get support from nature when it comes to saving water. Natural rainwater is ideal for watering the garden. Since rainwater also has a lower pH value than more calcareous tap water, even your plants benefit from it.
Catching water in a rain barrel is particularly suitable for watering in summer. Such a barrel should hold between 200 and 300 liters of water, but there are also larger models with 500 liters or more. However, the water should not sit unused in the barrel for weeks and get dirty, so you can estimate the amount you need before buying a water butt and choose the right size for your purposes. Rain barrels with a spout are also practical, so you can easily and purposefully pump water out of the barrel.
Even more rainwater can be collected in a cistern. If you want to use an underground tank as a water reservoir, however, you have to dig deep and dig deeper into your wallet. It can be worth it, because underground tanks hold up to 4,000 liters of rainwater and are connected directly to the rainwater downpipe. The water is pumped out by an electric submersible pump.
