Cuba: a tropical island, a communist state. Water is officially stated to be a human right in the in 2019 newly inaugurated Constitution of Cuba. This ideal of access to clean drinking water to all of the population is hindered by a multiplicity of challenges in its daily reality. Due to the growing population and the consequences of climate change, the natural sources of sweet water are no longer sufficient to provide everyone with enough fresh water. Water is rationed and people have to fill the tanks on their roofs during the one hour of running water in 2-5 days. Unique in Cuba is the combination with sixty year communism. The infrastructure on the island is heavily corrupted: more than 50 per cent of the available water is leaking away through porous pipelines. Renovation campaigns are being frustrated by the USA economic embargo. Despite these difficulties, in the non-automated, non-digitalized society an army of workers is sent to the streets every single day to guarantee fresh water to the Cuban people. This project focuses on the challenges and solutions of these workers: water truck drivers bringing water around to households and districts that lack water; the health brigade sending inspectors to check the hygiene of the water tanks, as well as fumigators who try to exterminate mosquitos and other insects to prevent the transmission of vector-borne diseases. Both the informal manner in which the bureaucratic system is executed and the inventiveness of the Cuban people to deal with their daily struggle for fresh water is highlighted in this project “Manifiesto del Agua”. Following the course of potable water on the island you get a deeper understanding of Cuban society; a profound insight in contemporary communist Cuba.
