Residents say water has been shut off from midnight until around 5 a.m. in recent nights.
“Despite repeated denials by officials, it appears the process of rationing has started” and citizens in parts of the capital “are deprived of water during the night,” Mizan News Agency, affiliated with the judiciary, wrote.
The daily Haft-e Sobh likewise reported sudden five-to-six-hour overnight cuts in drinking water across several districts, all without prior notice.
Reduced pressure across the city, the paper said, and declining surface and groundwater reserves had led to “serious instability” in Tehran’s water network.
The outages have lasted long enough to affect even households with backup storage tanks, according to the report.
Rising frustration
Haft-e Sobh quoted residents as saying the sudden shutdowns disrupted daily life. “When the water is cut off at night, we don’t know when it will return, so we can’t plan our use. Even tanks empty quickly,” one resident said.
