Water‑related incidents that began in July 2024 – sabotage in San Fernando, vandalism at the Cipolletti intake and scheduled maintenance that lowered pressure in Buenos Aires – have continued across Argentina. By early August 2026 SAMEEP reported that emergency cisterns in Presidencia Roque Sáenz Peña were filled and, on the afternoon of 5 August, the cistern became operational, allowing a gradual return of potable water to thousands of residents. President Nicolás Diez said technical teams were monitoring flow, pressure and valve performance and expected full normalization by that evening.

Parallel projects progressed: Aguas de Catamarca started replacing aging pipelines in Fray Mamerto Esquiú to improve pressure and reduce leaks, while the Buenos Aires province continued hydraulic works in Berazategui and Quilmes, cleaning and profiling watercourses ahead of the anticipated El Niño season. A scheduled power outage will affect Olivera on 6 August as crews repair a sub‑station component.

On 5 August 2026 SAMEEP confirmed that the water supply to Presidencia Roque Sáenz Peña was fully restored. President Nicolás Diez supervised the final technical steps, noting that the emergency cistern was operational and that distribution would resume progressively as network pressure is rebuilt. The utility reported no new technical problems and said monitoring would continue until service is completely normalised, ending the emergency for residents who had been without water for several days.

The episode fits a broader regional pattern of water‑service restorations and infrastructure upgrades, with similar emergency responses reported in Chile, Mexico and Bolivia, underscoring coordinated efforts to maintain essential services amid aging networks and climate‑related pressures.
