The Global Water Shower Challenge


The Water Shower Challenge


While Cape Town, South Africa, is about to cut water supplies, many other major cities around the world could face the same challenge by 2050


According to a scientific study published in the Nature Sustainability Journal, hundreds of cities could be affected by 2050. As explained recently in the journal  Le Monde, “because of global warming and the violence of precipitation, water evaporates or drains into the oceans, preventing the groundwater from filling up “. The BBC has identified the 11 cities that could be the first to get through this crisis. One way to sound the alarm and to empower individuals, even if the time when the water will run out seems inevitable.

The first cities threatened by “zero day” before 2030 are:

1- Sao Paulo,

2- Bagalore (Bengaluru)

3- Pekin,

4- Cairo,

5- Jakarta,

6- Moscow

7- Istanbul

8- Mexico

9- London

10- Tokyo,

11- Miami

Cities like Bagalore or Moscow are in water-rich areas, but because of polluting activities in the area there is not enough water to wash and drink.


The Global Water Shower Challenge (GWSC)!

E & S Communication wishes to contribute to the resolution of the global water issue by raising the awareness of urban populations around the world on the impact of their daily water consumption and on its excesses when it is not reasoned.

In collaboration with committed partners on climate issues, E & S Communication launches the “Global Water Shower Challenge” GWSC, an inter-city competition to see in which participating cities we find a population conscious and concerned by the problem of water. GWSC organizes in each participating citiy, sensitization campaign in collaboration with city authorities and major NGOs dedicated to water issues.


What is GWSC?

The GWSC is a Smartphone application that allows you to calculate your usual water consumption for washing and then calculate how much water you have saved by rationing your water intake every day by timing your shower duration.

When registering, each user joins the city where he lives.

Rankings are updated regularly.

1- Ranking of the largest number of participants in the same city,

2- Ranking of the largest percentage of participating population in a city,

3- Ranking of the largest amount of water spared in a city,

4- Ranking of the largest amount of average water saved per user in the same city,

5- Ranking…


For a city to be included in the Ranking, it must have at least 1,000 registered users and city authorities must have agreed to participate in the WSC awareness program (develop in partnership with partner NGOs)


Average reference time of a shower


Each year, the winning cities receive a free audit of a municipal major structure on water system efficiency by our technology partner.
