ALIMALAT EARTH DAM IN CHAMESTAN, MAZANDARAN

This project was a joint project between Sepano Construction Company and WEM in Chamestan, Mazandaran. WEM was in charge of project management and executive of whole work. Sepano was in charge of finance. The project started in September 1991 and completed in November 1994. The job was to construct a reservoir dam for irrigation of 800 acre of rice producing farms from Amol to Noor in Central Mazandaran. The dam was 200-meter wide at the crown and 28-Meter height at deepest point of river. The client was Mazandaran Water and Electricity Authority and the consultant was Reyab Consultant Engineers. The dam was an earth dam with a bentonite curtain and pure clay core and riprap cover. The job was done in three years that was 9 months later than schedule because in 1992 more than 200 days were raining and the core was clay and took several days for gaining back its optimized humidity and could be compacted to 100%.
