Mexico City, beyond being one of the biggest cities in the world, is also one of the most at risk global capitals in terms of water security. This was not always the case, however. In fact, much of what is now Mexico City used to sit on top of Lake Texcoco – a body of water now almost completely covered over by the massive urban sprawl of 24 million people. But even after the lake was sacrificed to accommodate the city’s growing population, there was still a network of rivers that flowed through the city, providing irrigation, drainage, and green space.
Starting in the mid 1900’s, however, the rivers became so polluted from discarded trash and human waste, which when combined with the explosion of personal cars in Mexico led local government to the decision to enclose these rivers in pipes and pave over them with new roads. Some of the city’s main thoroughfares — Rio Churubusco or Rio de la Piedad, for example — still bear the names of the waterways that they replaced. While there is still some form of running water underneath these roads, they are now more sewer than river.
Recently there has been rising interest among architects and environmental activists to dig up these rivers and restore them to their original state, cleaning the water in the process and providing natural space for locals to enjoy. Unsurprisingly these plans have not been wholeheartedly embraced by the government which does not seem interested in spending large sums of money on projects with little promise of economic returns. Yet that hasn’t stopped people from drawing up plans for what such a project might look like and architecture firm Taller 13 has been among the lead voices in advocating the benefits of a city through which rivers once again flow.
Since moving to Mexico City and starting a three year investigation into all facets of the city’s water situation, I’ve wanted to get a sense of the scale of these former rivers. Previously I’d driven along some of them and taken photos, but the real magnitude of the environment can’t be grasped from ground level. Instead I set aside my camera and travelled across the city with my drone and I think the footage gives a much better idea of both the size of the city and of the invisible rivers that were once above the surface.
