While reading about the water supply problems in Bogotá, I encountered a quote that applies to water-related challenges in many places of our planet, including Bogotá: “The thirst for water is above all the thirst of the poor” (attributed to the Uruguayan geologist Danilo Antón).
Bogotá has around eight million inhabitants and is rich in water to the east and west where the ‘cerros’ – a chain of hills part of the Andes- delimit the city’s borders.
Towards the south is one of the most astonishing ecosystems, a core regulator of water flows, and the biggest of its kind: the Páramo de Sumapaz (paramo appears to translate as “moor”). This holy place for the native indigenous communities Muiscas is the natural source of most of Bogotá’s water wealth and the source of the city’s most precious river: Río Tunjuelo.
As a result of the health and water problems of the late 19th century (e.g. dysentery outbreaks), the Sumapaz moor was stripped of its indigenous symbolism to become a scientific response to the need to obtain water for the city through the largest river, the Tunjuelo. Its waters supplied the first modern aqueduct to Bogota, and the river’s basin was then urbanized in less than 100 years, turning it into the home of two-fifths of Bogota’s population. As the direct solution for water problems at the beginning of the last centuries, the aqueduct from the river was initially planned to provide clean water to the growing capital city. However, it has failed in doing so.
Despite being a magical source of life, the Tunjuelo River is also the source of the thirst for equality. It passes through the south of Bogotá, where only people of the social strata 1 and 2 live (the two poorest in Colombia’s social stratification ‘support’ system). The river’s water is pumped to supply this part of the city. But, an increase in industrialization since the 60s has had two spillover effects: significant pollution and lack of clarity in water rights, leaving thousands of families without access to the rich, drinkable water of the river.
Industries producing detergents, tanning hides, producing concrete and mining (illegally) have dumped pollutants into the river over time. In 2022, the presence of illegal mining practices in the sectors surrounding the Tunjuelo River affected around one and a half million people who live and work in this part of the city due to the high sediment deposits produced by these industrial practices. So, instead of rocks, the riverbed shows a tapestry of disposable containers, dead animals, car tires and plastic bags tangled on the bank because of irresponsible and non-regulated commercial activities. And what is the effect? Thirst. Thirst for those who are excluded from having clean water.
But even this is a secondary problem from which only the most privileged among the poor in the south suffer. This part of the city still represents the thirst among the poorest among the poor in water-rich Colombia. Around 20,000 families live without any water service in more than 10 irregular settlements in the districts near the Tunjuelo River.
Bottom Line: Despite being rich in water resources, Bogotá’s poor have a big thirst for water.
