Chukha Hydroelectric Project

Encardio Rite provided geotechnical monitoring instrumentation for the Chukha Hydroelectric Project in Bhutan. This 336 MW run-of-the-river power plant features a 40 m high diversion dam with four spillway gates and a 6.5 km tunnel. Encardio Rite’s instrumentation package included foundation piezometers, strain meters, anchor bolt load cells, borehole extensometers, crack meters, temperature meters, and an automatic data acquisition system. These monitoring systems were crucial for ensuring the safety and efficiency of the project throughout its construction and operation.

Chukha Hydroelectric Project

Chhukha Hydropower Plant (CHP), is a run-of-the-river project. It is located at Chhukha Dzongkhag in the south-western part of Bhutan. The purpose of the project is to divert the water for the generation of electricity.

A 40 m high and 105 m long diversion dam having four spillway gates is used for discharging the excess water. Water from the diversion dam is conveyed through a 6.5 km tunnel. The installed capacity of the powerhouse is 336 MW.

Encardio-rite was awarded the sub-contract for supply as well as installation of safety monitoring instrumentation for the project. The instrumentation included:

Foundation piezometers
Strain meters – rosette with no stress-strain meter
Arc weldable strain gages
Anchor bolt load cells
Borehole extensometer – multipoint
Crack meters
Temperature meters
Automatic Data acquisition system
