Shall we waste water?
These tips pay off: Saving water means saving energy and money - but not in terms of convenience!
There is plenty of water in Germany. Even if the rivers and lakes offer a different picture in extreme dry seasons. But most of the water is underground. So there is a lot more water than we see. This figure also fits: only 17 percent of our water is actually used. And we only pay 0.2 cents for a liter of absolutely clean drinking water. So why should we save water? The answer is simple: Because it relieves the environment and the wallet - especially through savings in energy costs! Sounds complicated, but it's not. Here are a few background information and tips on how to save water sustainably.
Why save water?
Saving water is a good “habit” in Germany: Despite all the comfort and the highest hygiene standards, we only use 123 liters per person per day. In a European comparison, this is a good value. For comparison: In Romania, for example, the daily consumption is almost 300 liters per person, but in Lithuania it is only just under 100 liters. Why should we still try harder to save water?
One reason: Saving water also saves energy. Because a large part of the drinking water consumed is heated beforehand. At home, around 12 percent of energy consumption is used to generate hot water for showering, bathing and cleaning. If you save water, you reduce your water bill just like that of the energy supplier.
Danger! Saving energy with hot water is dangerous!
But not warming up the water properly can be dangerous. Do you have a storage tank for warm drinking water in the basement? A thermometer can be used to read how warm the water is in it. A drinking water temperature of 60 ° C is ideal. Anyone who lowers the temperature here in order to save energy is committing a serious mistake: If the water temperature in the storage tank is below 60 ° C, dangerous germs can multiply - especially legionella. If they are inhaled while showering, there is a risk of severe pneumonia.
In addition, water not only costs a lot of energy at home. The water suppliers also have to use a lot of energy to convey, pump and purify water. With every liter of water that we save, we also reduce the emissions that are attributable to the energy consumption of the water supplier.
Probably the most important reason “save for water” is definitely: That relieves the environment. Because drinking water becomes wastewater, which often flushes pollutants into the environment. In addition, our constant water extraction does not always match the fluctuations to which the natural water cycle is subject. Falling groundwater levels, for example, cause plants to wither during periods of little rain. In addition, they have a bad effect on the geology of the soil. So saving water always makes sense.
Here are a few tips on how the whole family can join in.
Tips for saving water in the bathroom
Anyone who saves water when using the bathroom every day also saves a lot of energy. Because most of the hot water is used for personal hygiene.
According to the survey by the Federal Association of Energy and Water Management, most of the water is used in the bathroom - predominantly hot water. Cold washing is not really an option. You don't have to do without comfort in order to save water on a sustainable basis. Here are a few better tips:
- Turn off the tap while brushing your teeth. Otherwise, depending on the setting, up to 10 liters per minute will flow out of the tap.
- Showering instead of bathing. A bathtub holds 150 liters, a 5-minute shower with a water-saving shower head only consumes 30 liters.
- Use the partial flush button or the stop button to flush the toilet. The partial flush usually only uses 3 liters, the large flush 6 to 9 liters of water.
Tips for saving water in the kitchen
The least amount of water in the household is used for cooking. Nevertheless, water can be sensibly saved in the kitchen:
- Use water-saving kitchen fittings! The best fittings get by with 5 liters per minute, the standard is over 10 liters. The flow rate can also be reduced with retrofitted jet regulators (e.g. from Perlator).
- Use the dishwasher instead of washing by hand! Modern dishwashers only use around 10 liters of water per cycle. Washing the same dishes by hand costs between 40 and 60 liters of warm water. The important thing here is: In order to really save water, the dishwasher should be really full.
Tips for saving water in the garden
Splashing yourself wet with water in summer is a great pleasure, not just for children. Watering the garden carelessly with a garden hose is expensive, however. Saving water helps save money here.
Longer “dry spells” without precipitation are also becoming more common in our regions. A look into the garden then says: watering is the order of the day! But that's expensive. Garden experts expect a water consumption of around 20 liters per week for every square meter of garden in the summer months. Here, too, clever tips help to save water:
- Collecting rainwater saves drinking water: the classic rain barrel on the downpipe of the roof drainage holds between 200 and 500 liters, an underground cistern can even bunker 1,500 liters and more. The advantage: Because the rainwater comes free of charge from the clouds and not from the water supplier, no wastewater fees have to be paid for it. In addition, there is usually no municipal precipitation fee for the introduction of rainwater into the public sewer network.
- Watering properly saves water. Garden fans know: only lawns should be watered with a sprinkler. Plants should be watered directly at the roots - not too often, but with enough water so that it can penetrate the soil. It is clear that the garden should only be watered in the morning and in the evening. Otherwise the precious liquid will evaporate directly and be gone.
- The right cut of lawn saves water. It is best not to cut the lawn too short in summer. Longer blades of grass provide shade to the ground and reduce evaporation.
With a little attention you can save a lot of water in everyday life. This not only saves this precious resource, but also saves a lot of energy when it comes to hot water. Because around 40 percent of our drinking water consumption is hot water. What tips do you have on saving water? Write your comment here. Thank you for letting us be part of it!13readers like this
