How to save water using it efficiently?

Tips on how to save water for efficient use

The average consumption of water per inhabitant and day in our country is between 250 and 300 liters . Which is quite a high figure for the real use that we need of water. Approximately the cost of water in a home is distributed as follows:

  • Shower and bathtub 35%
  • toilets 30%
  • Washing machine and dishwasher 23-25%
  • Cooking and drink 10%
  • Others 2-4%

Based on these data, from Reformayahorra, as experts in efficient energy , we want to answer the following question:

What can we do to save water?

  • Taking a shower consumes 4 times less energy and water than taking a bath
  • Using water “aerators” makes the water foam and we have the same sensation of quantity as without it, but with less expense
  • Place thermostatic taps that ensure the temperature of the water more quickly and reliably
  • Place toilets with double push button. 35% of the water we spend is in this function
  • Place devices to get immediate hot water and not waste the water that remains in the pipe until it reaches the temperature we want
  • Place an individual installation that recovers and reuses the so-called gray water from the sink, shower and bathtub to flush the toilet
  • And above all, the best way to save water is NOT TO SPEND IT USELESS.

We must begin to lose our fear of using these solutions, which have been on the market for some time, but until now no attention had been paid to them, and to have confidence in the new techniques currently provided by some manufacturers and installers.


Likewise, apart from trying to adopt good water consumption habits, there are two possibilities to capture and reuse it.

One way to do it individually and the other collectively.

How to save water individually

The homes that are part of a building can accumulate and reuse the so-called gray water that basically comes from your sink, shower and bathtub which, as we have mentioned before, approximately represents 35% of the water that we consume in our home and that, more or less , it would make up for the amount of water we use in the toilets. These systems can be located within the same home without occupying its useful surface.

How to save water Collectively

It would be a matter of locating both the warehouse and the technical room in a community area on the roof to, from there, supply all the building owners who want. Today “moving” water has a minimal electrical cost compared to that represented by the cost of water.
Just as important as the cost of water is to be aware that water is a very scarce good and an exhaustible resource. Although we live on a planet with a lot of water,

Only 0.007% of the water in the world, in all its forms, is drinkable.

Experts already recommend including rainwater harvesting systems in cities and their buildings.

A recent study carried out by the Universitat Autònoma de Barcelona (UAB) has reached the conclusion that it is very important to take into account this collection of water to be reused for toilet cisterns, irrigation, street cleaning and sewerage to avoid bad odors that they occur mainly in summer, etc.
