Mamloo Dam matters in the Hormuz Graph as part of Tehran’s southeastern water-security system, where reservoir management affects municipal supply, peri-urban agriculture, logistics districts, and fast-growing settlements around Pakdasht and Varamin-facing corridors. Its role is different from Latyan and Lar: Mamloo is more closely tied to the capital’s eastern and southeastern demand belt, where urban expansion and industrial land use increase pressure on water utilities. The asset connects public water allocation, drought exposure, urban-services resilience, agricultural demand, and investment risk around Tehran’s outer growth zones.
