Regardless of the capacity of the reservoirs in Spain, you must always approach their use responsibly. That’s why Miteco has published a series of tips for saving water at home.
Before you go to bed, write down the water meter reading and read it again when you wake up before using it. If the meter value has changed, there may be a leak.
Another silent leak is through the toilet. To find out if there are any, you can color the water in the box with a harmless dye, which makes it easier to eliminate water waste.
The seemingly harmless dripping of a tap can, over time, lead to significant water losses of around 30 liters per day. If you discover a leak of this type, it is best to fix it as quickly as possible.
If you are away from home for a few days and do not have an automatic irrigation system installed, it is better to turn off the tap. This prevents water loss due to small leaks or flooding due to unexpected interruptions.
