SALIENT TECHNICAL FEATURES  
Four (4) numbers Main cooling towers have been already provided by employer in  
Rihand Super Thermal Power Project Stage-III (2x500 MW) for condenser and unit  
auxiliary cooling water purpose. As the achieved cold water temperature is higher than  
design cold water temperature it is proposed to modify/augment the existing one  
cooling tower to achieve the design cold water temperature.  
The scope includes Design, Engineering, Manufacture, Supply, Construction, Erection,  
Testing & Commissioning works for Augmentation/Modification of existing one Induced  
draft Cooling Tower and associated equipment’s for Rihand Super Thermal Power  
Project-stage-III (2 X 500 MW).
