Dam Spillway Repair & Strengthening – Middle Bhotekoshi Hydropower Project

Dam Spillway Repair & Strengthening – Middle Bhotekoshi Hydropower Project

The spillway at the Middle Bhotekoshi Hydropower Project operates under intense hydraulic pressure, heavy sediment load, and frequent high-flow conditions. To maintain safe operation and extend the life of the structure, our team delivers a detailed repair and strengthening program addressing both surface deterioration and underlying structural issues.

The intervention enhances the spillway’s concrete profile, improves resistance against abrasion, and restores the integrity of zones affected by continuous flow and environmental exposure.
