Mamloo Dam
Located on the Jajrood River in Pakdasht County, Mamloo Dam entered operation in 2011 and supports municipal and agricultural water users across Tehran’s southeastern demand area. Its decision relevance depends on current storage, allocations, water quality and drought conditions, which vary over time.
Strategic and market-access role
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.
Operations, capacity & connectivity
Related use cases
Useful for Tehran water-risk assessment, urban-services screening, real estate resilience review, industrial and logistics site evaluation, public-project monitoring, and demand mapping for water efficiency or treatment solutions. Analysts can use it to assess how water constraints affect eastern Tehran, Pakdasht, Varamin-linked agriculture, and warehouse or industrial operations. Verification should cover current allocation rules, reservoir conditions, drought exposure, and utility-management arrangements.
Capacity and service area
Capacity: Design/installed reservoir volume: 250 million m³. Average annual supply capacity as of 28 June 2021: approximately 90 million m³ for drinking water and 120 million m³ for agriculture and industry. Service area: Southeastern Tehran, Pakdasht, Varamin, Gharchak and surrounding agricultural lands.

2011.
Constraints, risk & compliance
Operational constraints
Water availability is exposed to drought and water scarcity, which can affect reservoir levels and supply availability.
Key risks and compliance considerations
Drought and water scarcity are material risks to reservoir levels and water availability. Concerns were also raised in 2019 about potential source-water pollution linked to agricultural runoff and upstream industrial activity.
