Dam Spillway Repair & Rehabilitation – Kaligandaki-A Hydropower Station
Dam Spillway Repair & Rehabilitation – Kaligandaki-A Hydropower Station
The spillway of the Kaligandaki-A Hydropower Station operates under high flow conditions and continuous abrasion from waterborne sediments. To restore performance and structural reliability, our team executes a comprehensive rehabilitation program focusing on concrete repair, surface strengthening, and hydraulic protection measures.
The work enhances the spillway’s durability, improves flow efficiency, and safeguards the structure from long-term wear, ensuring stable and uninterrupted hydropower operation.
