Photographer Carlos Cazalis explains the historical and geographical context of water use and management in Mexico City before the Conquista and into the modern age.
Mexico City with 20 million people, at high altitude, inside a valley basin where 500 years ago five lakes converged into one in a semestral rain season, must now control distribution and even ration water to its citizens.
Excessive rainfall today is not captured for consumption, deforestation of the valley and permeabilisation of the soil from uncontrolled urbanisation often causes flash flooding with sewage waters. Since the 1970’s, 25% the city’s water supply is practically imported through an extensive 150 km pipeline originating in seven man made lakes in the state of Mexico.
Join us to hear these stories and more about the district of Iztapalapa 2 million people living with water shortages; of the longest sewage canal in the world leading to Atotonilco, the largest sewage treatment plant in Latin America; and finally the possible death of Xochimilco’s floating gardens.
