Sustainability and mindfulness start in our everyday lives. It's often about the little things that add up to big things – the more people pay attention to them around the world. Today we explain how much water a dishwasher can use and how you can reduce the amount of water you use. Effectively reduce toilet water consumption.
But first we ask ourselves: Why is this important?
Older toilet flush valves can Consume up to 14 liters of water per flush. Even one person uses a lot of water. If we extrapolate this figure to a family of several people, this is an enormous amount of water used just to flush the toilet, as this brief overview shows:
Families of four people in Germany
We assume that
We can all save water by flushing the toilet without sacrificing our sense of well-being. And we should, because we consume precious drinking water with every flush.
Do you want to save water? Then you shouldn't flush the toilet - right? That would be the most effective, but also the most unhygienic option. That's why we suggest a good alternative: Swap the conventional one for a modern flushing tank with low water consumption. This is an investment that really pays off.
You can save a lot of water if you use a timely and efficient water supply. Dual flushing with two buttons or a start/stop button have.
Because such solutions only consume around three to six liters per rinse. For our calculation example from above, this means the following:
Again, we assume that our family flushes 16 times at five liters of consumption per keystroke. They consume 80 liters per day, just under 29,200 liters (29.2 cubic meters) per year. Our exemplary family from Germany now pays just under 88 EUR for their toilet flushing water consumption per year.*
Our family not only saves money through EUR 100 per year in water costs, better still, they saves approx. 13 cubic meters of precious drinking water.
Tip:It is advisable to clean and descale the water tank at least once a year. This will keep it working for longer and minimize the risk of leaks, through which liters of water run unnoticed and, above all, unused into the sewage system. However, with a new economical drainage tank you also avoid this risk.
In our calculation example, we have only considered the "usual" use of a toilet in terms of water consumption. But there are many more reasons to flush. Above all, the regular cleaning of ceramics or the lengthy rinsing process. And so, in addition to economical rinsing, there are another small lever that you can set in motion.
Modern flushing valves and intelligent water supply systems optimize the flushing performance with only 4.5 l of water consumption per flush and certain designs, such as the the rimless design of hansgrohe toilets. This modern design also reduces the amount of cleaning required. This means that there is no need for frequent flushing until the toilet is really clean. This also saves water.
Efficient water use is also a special feature of the hansgrohe toilets. Enabled by a well thought-out internal geometry, in combination with the appropriate storage tank, it can support you in the economical and environmentally conscious use of the precious resource of water.
Durable and environmentally friendly glazes have clear advantages in the area of cleanliness and hygiene because you can clean the toilet more easily and quickly with less water consumption.
When you choose a toilet from hansgrohe, you can choose from two solutions for effective glazes:
There are a number of options, live more consciously at home: from the sustainable wooden washbasins to solutions that are not so obvious at first glance. Or did you know that you can use graywater as toilet flush water? This includes wastewater from the sink, bath tub, shower and washing machine. All you need is a small recycling system.
The fact is, however, that genuine investments in modern, environmentally friendly toilets because apart from gray water and rainwater solutions, every flushing process uses valuable drinking water. And the savings are so simple! That's why it makes sense to replace both the toilet and the cistern.
You also pay less if you reduce the water consumption of the toilet. As a result, your investment will pay for itself over time and, in the long term, not only ease your conscience but also your wallet.
* This assumption is based on an average gross price of EUR 3 for drinking water and wastewater per cubic liter;
**Glaze that inhibits bacterial growth on the product (refers exclusively to Escherichia coli ATCC 8739 and Salmonella enterica ATCC 13076, test ISO 22196: 2011-08)
Depending on the flushing cistern and toilet, up to 14 liters of drinking water are discharged into the sewage system per flush.
A very efficient way is a new flushing tank, because with modern solutions such as a dual or economy function, you can reduce water consumption by several liters per flush.
An optimized interior geometry and sensible flushing technologies reduce the toilet's water consumption enormously. In addition, modern toilets are often rimless, which reduces the cleaning effort and thus also the consumption of cleaning water.
Make sure that the toilet is provided with a basic dirt-repellent and/or bacteriostatic glaze This special glaze prevents the growth of bacteria (except Escherichia coli ATCC 8739 and Salmonella enterica ATCC 13076, according to test ISO 22196: 2011-08), which ensures greater hygiene and lasting well-being in the bathroom.
Graywater includes wastewater from bath tubs, showers, sinks, dishwashers and washing machines. With an appropriate recycling system, you can also use it as toilet flush water.
