Aguas de La Habana has announced that water supply will be disrupted in various areas of the capital this Tuesday, October 6, due to electrical work on major water sources and necessary repairs and maintenance on the 78-inch pipeline from Cuenca Sur.
The state-run company stated that these disruptions will begin at 6:00 a.m. and continue until 8:00 p.m. However, in Centro Habana and Habana Vieja, the impact will be more concentrated in the afternoon and evening hours.
Although the official statement mentioned disruptions in "zones of the five central municipalities," Aguas de La Habana specifically listed six affected areas: Plaza de la Revolución, Cerro, Diez de Octubre, Boyeros, Centro Habana, and Habana Vieja.
The interruption is linked to a "green light" scheduled by the Basic Electric Organization (OBE) at Cuenca Sur as part of efforts to enhance the stability of electrical service to the city's primary water supply sources.
During this downtime, Aguas de La Habana will also carry out "repair and maintenance tasks at specific points on the 78-inch pipeline."
Areas Impacted by the Water Interruption
In Plaza de la Revolución, areas directly supplied by Cuenca Sur will experience service disruptions.
Residents in Cerro will see interruptions in neighborhoods such as Martí, Cepero Bonilla, Casino Deportivo, Santa Catalina, Palatino, and Las Cañas.
In Diez de Octubre, the affected areas include Santos Suárez and Tamarindo.
Boyeros will face the most extensive list of affected zones: Miraflores Nuevos, Ciudad de la Construcción, Altahabana, Capdevila, Embill, La Fortuna, Mazorra, and Río Cristal. Aguas de La Habana anticipates low water pressure and shortages in these regions.
Centro Habana and Habana Vieja will mainly experience disruptions during the late afternoon and evening on Tuesday.
The company has assured that priority will be given to Hermanos Ameijeiras Hospital and that water pumping will continue to the Príncipe area and other hospitals.
Gradual Restoration of Service
Aguas de La Habana urged residents and affected socioeconomic centers to take water conservation measures to mitigate the impact of the service interruption.
Once repairs and maintenance are completed, the water supply will gradually return to its usual schedule, according to the company.
"Aguas de La Habana apologizes to users for the inconvenience caused," the entity stated, advising residents to stay informed through their official channels.
Persistent Issues with the 78-Inch Pipeline
This scheduled work highlights ongoing issues with the 78-inch Cuenca Sur pipeline, which has experienced failures throughout 2026.
In August, a significant break left six municipalities without water, with leaks detected at locations such as Manresa and Espina de Pescado.
Havana's Ongoing Water Crisis
The new disruption occurs amid a prolonged water supply crisis in the capital, worsened throughout 2026 by breakdowns, deteriorating infrastructure, and electrical issues affecting water pumping.
In April, power outages left over 200,000 Havana residents without regular access to potable water.
By May, the National Institute of Hydraulic Resources reported 376,055 affected individuals. By July, the number exceeded half a million.
In September, Yosvany Rubí, director of Aguas de La Habana, acknowledged that more than 577,000 people faced difficulties with water supply.
Nationally, Cuban authorities admitted in early October that 2.7 million people experienced full or partial service outages. 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 Electrical Dependency Issue
The situation further highlights the critical dependency on the electrical system for water supply in Cuba. In Havana, 87% of the water supply system relies on electricity for pumping.
Out of the 480 key pumping stations nationwide, only 135 are connected to circuits protected from power outages, meaning blackouts directly impact water supply.
In late September, Miguel Díaz-Canel visited the Cosculluela source in Boyeros—the second most important in the western system and lacking comprehensive rehabilitation for over 60 years—to oversee ongoing projects.
Authorities also announced plans to install 200 MW of solar photovoltaic generation for water pumping in Havana, aiming to reduce dependency on the National Electric System by early 2027.
