Subject : PUMPING STATION FOR LAR DAM RESERVOIR (Turn key)
Place : polor-sade lar
Taskmaster : Tehran Regional water authority
Consultant :Tehran Boston consulting Engineers
Start : 1998
End : 2000
Description :
This project located at right bank of Lar dam reservoir, near Polur city in Tehran province. Special structure of bed rock at right bank of reservoir (existence of Karstic zone with lots of faults) causes escaping of water from the bed and bulwarks of the reservoir. This flow might be more than 5 m3/s. The more consumption the lower level of water, and the intake tunnel will be unusable. So a pumping station was constructed with maximum discharge of 18.5 m3/s for supplying water to Lar-Kalan water transmission tunnel.
