Iran is confronting a severe water crisis amid a prolonged drought and a heatwave that have drastically reduced water supplies, particularly in Tehran. The capital's reservoirs are at critically low levels, with current water storage at approximately 14 to 20 percent of capacity, the lowest in a century. The Mamloo Dam, a key water source, is at risk of drying up within a month, with other dams such as Latyan, Lar, and Karaj also facing significant depletion. Authorities have reported a 43 percent decline in water inflow to the dams over five consecutive years of drought. The Ministry of Energy and Tehran's Water and Wastewater Company have urged residents to reduce water consumption, warning that continued overuse could lead to stricter water management policies, including pressure reductions and potential supply disruptions. Tehran’s water consumption is reportedly double the global standard, while residents pay only about 3 percent of the actual cost of water. The Iranian president has highlighted the country’s precarious situation, emphasizing the risk of dam reservoirs drying up in the coming months if consumption is not curtailed. The crisis is compounded by industrial wastewater contamination and increasing demand, leading to concerns over infrastructure strain and public health. The government is calling for urgent conservation measures to avert a collapse in water supply and related energy shortages during peak demand periods.
