This documentary delves into the experiences of four older people whose lives were marked by the rivers, lakes and canals of Mexico City, when water was much more present in the metropolitan area than it is today. This documentary seeks to narrate how we have lived and coexisted withwater, through the eyes of those who have witnessed the profound transformations of a capital which slowly drained away its water and replaced it with layers of concrete. The multivocal narrative will map the fading memories of our characters, juxtaposing everyday stories of water depletion in Mexico City.The Basin of the Valley of Mexico is a mountainous region made up of constantly overlapping multiple layers. A closer look reveals how the enormous growth of the city meant that water had to be dammed, diverted, piped, and removed. Our need to find more places to settle had the consequence of displacing rivers and lakes.In the process, we stopped coexisting with the bodies of water once found throughout the city. Today, it is very difficult to preserve and to get enough water to the 25 million inhabitants of this metropolis; water scarcity is already a serious problem.Paradoxically, just a few hours of rain are enough to paralyze the entire city and remind us that we inhabit a zone that only a few decades ago was a city of lakes. In the past, people coexisted with water in different, more symbiotic ways. We, on the contrary, have a much more difficult relationship with it.When we observe the layers of concrete that are built and destroyed on a daily basis in the city, it might seem that the rivers and lakes disappeared long ago. The story of the mythical Tenochtitlan (that we were taught at school and that we see represented in scale models at museums) makes us think that it was long ago that these waterways ceased to be part of the immediate context. The canals of Xochimilco and Tláhuac seem reminiscent of the very distant past.Traveling around the Basin of the Valley of Mexico, we find public baths gradually closing down, electric dynamos at rest, rivers that are piped and converted into roads, aqueducts in ruins, dryfountains and wells, abandoned water parks, reservoirs turned into garbage dumps, etcetera.Each of these remains tells the story, in a fragmented manner, of the various ways in which water traveled across the metropolis and was detained by its growth. In many of these places it is still possible to meet elderly people who lived near these rivers and lakes and were able to bathe and swim in them. These people experienced first-hand the story of the water in our city.
