WATER USE: GOOD HABITS

Use water responsibly: don't waste it

#environmental sustainability #innovation

Salt water makes up over 97% of the water on the planet. Two thirds of the fresh water is trapped in glaciers and the polar ice caps, and most of the remaining third is in the ground or in underground aquifers. Conclusion: there is very little water available for living things.

Nearly 800 million people lack access to potable water, and nearly 4 billion live under water stress at least one month out of the year. Of these people, nearly 1 billion live in the poorest regions of India, and another 900 million in the poorest regions of China.

THE RISE IN THE USE OF INDUSTRIAL AND DOMESTIC WATER

International organisations estimate that total demand for water will double by 2050 due to the growing demand for water in industry and agriculture, as well as the rise in domestic consumption caused by mass migration from rural areas to cities. Today 3.9 billion people live in cities; by 2030, this number will be 5 billion. That is why all of us must use water responsibly and learn habits that reduce water consumption, such as, for example:

HOW TO USE WATER THE RIGHT WAY?

With these simple habits we will be able to considerably reduce water consumption whilst also using water properly:

 Periodically examine water taps, plumbing and piping, both indoors and outside of our homes, to prevent leaks.

 Use rainwater catchment systems to collect water for use in the bathroom or to water plants...

 Collect the shower water that comes out while waiting for it to heat up to use it for other purposes.

 Install water-saving bathroom fittings. If your cistern is not ecological, drop a bottle filled with sand into it.

 Do not use the toilet as a waste bin: each flush of the toilet wastes 6 to 10 litres of water.

 Install aerators on your taps to mix the water stream with air, saving up to 40% of the water.

 Cover swimming pools when they are not in use to reduce water evaporation.

 Wash vehicles in facilities designed for that purpose.

For years now companies and institutions have been researching and implementing vital technological advances to achieve rational water consumption both industrially and domestically. But sustainable consumption is everyone's responsibility. As John Fitzgerald Kennedy said, "anyone who can solve the problems of water will be worthy of two Nobel prizes — one for peace and one for science."
