Second Partial Project: Water
Water availability in Queretaro per habitant is 1,500 cubic meters according to CEA
In 2010, Mexico's yearly water availability per habitant was 4230 cubic meters
97.5% of the Earth's water is salt water
2.5% is fresh water
From which 0.3% belongs to lakes and rivers
99.7% belongs to glaciers, polar caps and underground deposits
844 million people don´t have access to drinkable water in which 159 million people depend on superficial water.
According to UN data, in 2020, 60% of the world's population is estimated to live in cities
For 2050, one in every four people will live in a country in which water availability is an issue

unbalanced river and lake ecosystems that can no longer support full biological diversity
deforestation from acid rain
Contaminated water generates diarrhea,dysentery, typhoid fever and poliomyelitis and causes 502 000 diarrhea deads a year.
organic, inorganic,radioactive and acid base.
Solvents from industrial work
Water is at the core of sustainable development. It is essential for socio-economic development, healthy ecosystems and human survival itself
The UN promotes environmentally sustainable economic policies. This would address human impact maintain productive ecosystems
The challenge is to maintain water resources to maintain a balance between Natural and built infrastructure
Creates a series of guideliness about water quality and the safe use of waste waters.
Colaborates with the UNICEF to create the tool "WASH FIT" which objective is to guide the primary centers of health with low incomes by the use of specific measures and by clasifying risks by priorities
'Acueducto II' takes water from Montezuma river and delivers it to Querétaro city, also this hydraulic technology is environmental friendly
