Water for cities: responding to the urban challenge is the theme of the celebration for the year 2011, and aims to highlight and encourage governments, organizations, communities and individuals to participate actively to meet the challenge of urban water management.
World Water Day provides a unique opportunity to draw attention and create momentum that compels governments to intervene, the international community, civil society and citizens. It is anticipated that this day, his organization is one of the hundreds of institutions to organize events related to Water for Life. " It is expected that each country will celebrate World Water Day in its own way.
To get home, the water makes a long journey. First of all, is stored in a dam. From there, it is sent to the plant purification, which is subjected to chlorination processes (eliminating algae and bacteria), aeration (to remove bad tastes and odors), sedimentation, filtration (to remove the mud) and a second chlorination. Then, powerful electric pumps circulate water through a complex system of pipes. It takes a lot of energy and money to pump water 24 hours a day. Finally, the water we drink at home, leads to a sewer network, and thus the cycle begins again and again.
Where does the Water?
Only 1% of the world's water is in Africa, America, Asia, Europe and Oceania. At first glance, the water on the continents seem abundant, but in reality it is not. Water reserves on Earth are distributed as follows: Oceans and seas (97%), ice caps and glaciers (2%), Groundwater (0.75%), and Rivers and Lakes (0.25%).
