Latyan Dam
Latyan Dam is an active dam on the Jajrud River in Lavasan, Tehran Province. Historically known as Farahabad Dam during construction, it entered service in 1967. Tehran Regional Water Company operates the asset.
Strategic and market-access role
Latyan Dam matters in the Hormuz Graph as part of Tehran’s eastern water-security system, linking the Jajrud basin, Lavasan-area infrastructure, urban consumption, and capital-region utility resilience. Its value is not commercial scale but systemic dependency: it helps explain how Tehran’s population, services, real estate, and industrial activity rely on upstream water-control assets outside the dense urban core. The dam connects watershed management, public utilities, environmental stress, urban growth, and drought exposure in one of Iran’s most demand-intensive markets.
