A major breakdown in the 78-inch main pipeline from the Cuenca Sur supply source has left six districts in Havana without water since Thursday. The emergency shutdown was declared by Aguas de La Habana, the water utility company responsible for the city's central supply system.
As reported in an official statement on Facebook this Friday, the disruption results from a "significant breakdown" in the pipeline, further complicated by three additional leaks found in the same supply source. The company has not provided a specific timeline for when the service will be restored.
The municipalities most directly impacted include Plaza de la Revolución, Diez de Octubre, Cerro, Centro Habana, Habana Vieja, and a section of Boyeros, affecting hundreds of thousands of residents in the heart of the Cuban capital.
Efforts to Fix Critical Water Supply Issues
Technical teams are working tirelessly at three critical sites: Manresa, Espina de Pescado, and Wells 9 and 12. The company emphasized that their "primary objective is to resolve the breakdown and leaks as quickly as possible."
While these teams work with no defined deadline, Aguas de La Habana has called for "understanding and patience" from the public, urging them to stay updated through official social media channels.
Infrastructure Challenges and Historical Context
This incident is not an isolated one. The same 78-inch pipeline from Cuenca Sur underwent several interventions in 2025, including a costly overhaul in September of that year, replacing a section with two parallel pipes.
Just last week, another breakdown in a 1,000 mm pipeline in the Sistema del Gato left areas such as Los Camilos, Regla Zona Baja, and Casa Blanca without water, with further impacts in Regla, La Habana del Este, San Miguel del Padrón, Guanabacoa, and Diez de Octubre.
The aging water infrastructure in Havana is a structural problem. The main pipelines have been in continuous use for 60 to 70 years without adequate replacement. Estimates suggest that between 40% and 70% of pumped water is lost through leaks before reaching homes.
Cracks in the pipes result in insufficient pressure, allowing wastewater to be drawn into the potable water system, posing a serious health risk that residents have been vocally criticizing.
"Sewage water is coming through our pipes," lamented one affected resident in the Facebook group Victims of Aguas de La Habana.
Impact of Power and Economic Struggles
With 87% of the pumping system reliant on electricity, power outages directly impact water supply. The number of Havana residents without regular water access surged from 200,000 in April to over 500,000 by July, according to Aguas de La Habana's data.
In the absence of structural solutions, the informal market has seen soaring prices: a 55-gallon tank can cost up to 2,500 pesos, and a full water truck has reached prices as high as 60,000 pesos in the most affected areas, according to various accounts.
