Aguas de La Habana announced disruptions in the water supply this Tuesday, October 6, in several areas of the capital due to electrical work at the main supply sources and repair and maintenance work on the 78-inch Cuenca Sur pipeline.
According to the informative note published by the state-owned company, the disruptions will begin at 6:00 a.m. and will last until 8:00 p.m., although in Centro Habana and Habana Vieja they will be concentrated during the late afternoon to evening.
The announcement stated that the impacts will cover "areas of the five municipalities in the city center."
However, the company itself listed six municipalities: Plaza de la Revolución, Cerro, Diez de Octubre, Boyeros, Centro Habana, and Habana Vieja.
The interruption is related to a "clear path" anticipated by the Basic Electric Organization (OBE) in Cuenca Sur, as part of the efforts to improve the stability of the electric service from the main supply sources in the city.
Aguas de La Habana will take advantage of the shutdown to carry out “repairs and maintenance on specific points in the 78-inch pipeline.”
These are the affected areas
In Plaza de la Revolución, service will be affected in the areas that receive water directly from Cuenca Sur.
In the Cerro, the neighborhoods of Martí, Cepero Bonilla, Casino Deportivo, Santa Catalina, Palatino, and Las Cañas will be affected.
In Diez de Octubre, the impacts will reach Santos Suárez and Tamarindo.
Boyeros has the most extensive list of affected areas: Miraflores Nuevos, Ciudad de la Construcción, Altahabana, Capdevila, Embill, La Fortuna, Mazorra, and Río Cristal. In these locations, Aguas de La Habana has warned of low pressure and water shortages.
In Centro Habana and Habana Vieja, the disruptions are expected in the afternoon-evening of Tuesday.
The company stated that it will prioritize the Hermanos Ameijeiras Hospital and will maintain pumping to the Príncipe area and to hospitals in the vicinity.
The service will be gradually restored
Aguas de La Habana urged the population and affected socioeconomic centers to implement water-saving measures to mitigate the impact of the interruption.
Once maintenance and repair work is completed, the supply will gradually be restored to its usual schedules, as the company reported.
"Aguas de La Habana" apologizes to users for the inconveniences caused," concluded the entity, which also urged residents to stay informed through its official channels.
A driver with a history of breakdowns
The scheduled work this Tuesday once again focuses on the 78-inch driver from Cuenca Sur, which has experienced malfunctions during 2026.
In August, a serious break left six municipalities without water simultaneously, with three leaks detected in locations such as Manresa and Espina de Pescado.
The water crisis in Havana
The new interruption comes amid an ongoing water supply crisis in the capital, worsened in 2026 by breakdowns, the deterioration of infrastructure, and electrical problems affecting pumping.
Power outages left more than 200,000 residents of Havana without regular access to drinking water.
In May, the National Institute of Hydraulic Resources confirmed 376,055 affected individuals. In July, the number surpassed half a million residents.
In September, the director of Aguas de La Habana, Yosvany Rubí, acknowledged that more than 577,000 people faced difficulties with the supply.
At the national level, Cuban authorities admitted at the beginning of October that 2.7 million people were experiencing total or partial disruptions to their service.
The United Nations Office for the Coordination of Humanitarian Affairs (OCHA) raised the estimate to 3.5 million people without access to running water.
The dependence on electricity exacerbates the problem
The announced impact again highlights the close dependence of the water supply system on the electricity service. 87% of the supply system in Havana relies on electricity for pumping.
Out of the 480 fundamental pumping stations existing at the national level, only 135 are connected to protected circuits against power outages, which means that blackouts directly impact the water supply.
Miguel Díaz-Canel visited the Cosculluela fountain at the end of September, in Boyeros— the second most important in the western system and with over 60 years without a comprehensive rehabilitation— to oversee the works being carried out at the facility.
The authorities also announced the installation of 200 MW of photovoltaic solar generation designated for water pumping in Havana, with the stated goal of reducing dependence on the National Electric System by early 2027.
