Quick wins can also be found in the bathroom and toilet. Is the toilet in need of replacement? Toilet bowls are almost always made of ceramic, there is little to choose from. But there is a choice in the size of the toilet bowl and the cistern. So if you want to save water, opt for a modern toilet that flushes with two buttons: with 3 or 6 litres of water. Don’t forget to actually use that 3-litre flush, otherwise the savings will be limited.
A modern water-saving shower head uses considerably less water without compromising on shower comfort. Standard shower heads use 10 to 15 litres of water per minute, while a water-saving showerhead can reduce this water flow to as little as 5 litres per minute. It reduces the flow and adds air to the water, which means you experience a normal powerful jet that remains pleasant. Even a rain shower or another luxury shower does not necessarily have to waste water. Pay attention to the volume flow class, this must be S (max. 6 l/min.). An important additional advantage is that less water needs to be heated.
Volume flow classes
When choosing a new shower head, take the flow class into account. The flow class indicates how many liters of water flow from the tap per minute. This can generate a significant savings on your shower water consumption.

A water-saving toilet has a flush system with a selector switch that allows you to choose between 3 or 6 litres instead of 9 to 12 litres for a traditional toilet. The more often the toilet is used, the more sense it makes to purchase a modern toilet. For example, for a 4-person household, the toilet will pay for itself in 4 to 9 years, whereas for a single-person household, it can take up to 20 to 35 years. Is a new toilet not an option? For just 6 euros, you can buy a flush stop for in the reservoir. This will result in savings without spending much. Please note, the savings are considerably less than with a modern toilet.

A standard urinal uses about 4-5 liters of water per flush. A waterless urinal uses almost no water. The urinals are constructed in such a way that the urine flows out past a valve or sealing liquid. Water is only required for cleaning.

“Dankzij de waterloze urinoirs besparen we 1,4 miljoen liter schoondrinkwater op jaarbasis. Het scheelt ook in het onderhoud, we hoeven nog maar twee keer per jaar de urinesteenaanslag te verwijderen. Wat veel tijd en geld scheelt. "
Rainwater or greywater can be used for example for flushing the toilet. The water is collected in a reservoir, possibly cleaned, and then used in the toilet. In an ultimate situation, you no longer use drinking water to flush with. This often requires a larger intervention, because a separate pipe system may have to be installed to separate greywater and/or rainwater from drinking water. This is often a costly and complicated modification in existing buildings.

“De waterbeparende kranen gaan nu zo’n 20 seconden aan en dan stoppen ze. In het verleden gebeurde het wel eens dat een kraan een hele nacht had open gestaan. Dat was zo enorm zonde. We besparen met deze kranen nu 1,4 miljoen liter schoon drinkwater op jaarbasis."
With a flow restrictor, you will consume less water during, for example, washing your hands. Without sacrificing comfort, you save (hot) water at the wash basin tap. At the kitchen tap, the flow restrictor can be experienced as less practical, because it takes longer to fill a bucket or saucepan. Many faucets already have a flow restrictor, and otherwise they can be purchased for a few euros. This will pay for itself in one year, a real ‘quick win’.
