How efficiently do you save water
The 11 best household tips
Since the end of the 1970s, the average water consumption in Switzerland has fallen by 24 percent despite the increasing population: According to the Federal Office for the Environment (FOEN), the average water flow from the taps in Switzerland today 300 liters of drinking water per person per day. But only a fraction of the clean drinking water is actually drunk: It is used for cooking, cleaning and washing, for hygiene purposes and for watering the garden.
Wherever water is used, it can also be saved. Saving water not only conserves water as a resource, it also has a positive impact on household energy costs and, last but not least, on the environment. Because a lot of energy is required for transport, heating and wastewater treatment. With these 11 water-saving tips you will also save energy and save money.
Saving water sensibly: 11 simple tricks
The best tips for saving water are also the simplest. From the bathroom to the kitchen, there are many options in the entire household where water consumption and thus energy consumption can be reduced quickly.
By the way: Those who use hot water sparingly achieve the greatest energy-saving effect, because according to the Swiss Gas and Water Association (SVGW), the energy required for hot water is around 150 times greater than that for cold water.
Save water in the bathroom
1. Take a shower instead of a bath
Probably the most frequently mentioned tip for saving water is really worth it: While a full bathtub holds around 200 to 250 liters of warm water, in the shower you use around 15 liters per minute and with an economy shower only about 6 liters per minute. If you minimize the shower time and turn off the water while lathering, you use a fraction of the water that is needed for a full bath.
2. Use the correct attachment for the faucet and the like
The easiest way to save water in the bathroom is to turn off the tap while shaving, brushing your teeth and while soaping your hands. You can also save water with a water-saving shower head and a flow limiter for the tap.
Particularly worthwhile:To do this, simply replace the sieve insert with an economical jet regulator. One of these costs around 7 francs, which is amortized after a good 3 months. To ensure that you buy the right insert, we recommend unscrewing the existing aerator and taking it with you to the hardware store. So you can easily compare the size.
When buying economy fittings and inserts, pay attention to the efficiency class. Good sanitary products have class A. More information can also be found in the Water Fun brochure from Energie Schweiz.
3. Use toilet flush with flush stop
Some toilet flushes have a built-in flush stop. This means that you can only flush each toilet for as long as it is really necessary, thus saving a lot of water every time you go to the toilet.
Did you know? If a toilet does not have an economy flush, a water stop can also be used in the cistern.
Save water when washing
According to the FOEN, the declining water consumption in Switzerland is due in particular to increasingly economical household appliances. This mainly includes washing machines and dishwashers. Therefore, when buying new devices, pay attention to the electricity and water consumption. Only buy devices with the highest efficiency class on the energy label.

4. Load the washing machine correctly
If your favorite trousers are dirty, they quickly do a wash even though the machine is only half full. A half-full washing machine needs just as much water as a full one. It is therefore sensible and efficient not to switch the washing machine on until it is really full. If you live in a shared apartment, you can do laundry with friends or flatmates to save energy and water.
But be careful: If the machine is too full, the washing result will deteriorate. Fill the washing machine without squeezing the laundry. If there is still room for a shirt on top, the machine is optimally filled. With delicates and wool, it can be a little less.
5. Select the economy program
Modern washing machines usually have economy or eco programs. These usually run longer, but have lower water consumption. Overall, the washing results and the energy balance of these economy programs are significantly better than those of short programs.
6. Avoid prewash programs
Pre-wash programs are used to remove particularly stubborn stains from clothing. It is more water-saving and energy-efficient if you soak heavily soiled clothes before washing or pretreat them with gall soap and a little cold water.

7. Wash fruits and vegetables in the bowl
Fruits and vegetables should not be washed under running water, but in a bowl before consumption. This not only saves water when washing yourself, but you can also reuse the water and use it to water indoor plants, for example.
8. Use the dishwasher
It's hard to believe, but: because of their high energy efficiency and low water consumption, today's appliances save a lot of water compared to washing dishes by hand. If you don't have a dishwasher, it is worth washing dishes in the full sink instead of under running water.
Save water in the garden
In everyday life, a lot of water can be saved not only inside, but also around the house.
9. Collect rainwater
Collect rainwater in a rain barrel: It is ideal for watering garden and indoor plants and is therefore a valuable resource. Cooled boiling water from eggs, potatoes and vegetables is also ideal for watering plants.
10. Lower water consumption thanks to the drip hose
A lawn sprinkler consumes many liters of water and also does not water in a targeted manner. A drip hose is significantly more water-saving.
11. Pour properly
When watering the garden, water can be saved by pouring the rainwater onto the ground directly in the root area. Do not shower the plants, but water them specifically and preferably in the evening or early in the morning so that the water does not evaporate again immediately.
Instructive: Grünstadt Zurich invites you to take courses again and again, for example about sowing or planting native and site-appropriate plants and much more.
