CHAPTER – 1 PREAMBLE

1.1 Introduction Peoples Energy Limited is being developing Khimti-2 Hydroelectric Project (48.8 MW) located in the

border of Ramechhap and Dolakha districts of Janakpur zone. Khimti River is a tributary of Tamakoshi

a major branch of Saptakoshi river system of Nepal. The Khimti River originates at EL. 4500m and

converges with the Tamakoshi River at EL. 600m. The total drainage area of the Khimti River is

492.4km2, and the drainage area in front of the intake and powerhouse is 295.34km2 and

351.4km2respectively. The river section from the dam site to powerhouse is about 7km long. The

ridges on both banks are at EL. 2,300~3,000m; the riverbed at the dam is at EL. 1,627m; the riverbed

at the powerhouse tailrace is at EL. 1,278m. The run-of-river development scheme is selected.

The headworks site is located at Rasnalu/Gokulganga Rural Municipality of Ramechhap and Jiri

Municipality of Dolakha district whereas the powerhouse site is located at Simlep and

Hawa/Tamakoshi Rural Municipality of Dolakha District. The headwork is located about 150m

downstream the confluence of Jiri Khola and Khimti Khola with headrace alignment passing along the

right bank of Khimti Khola and powerhouse site also located on the right bank.

3.4 Progress work in Detail

3.4.1 Access Road Headworks Area-Dharapani Road (Ramechhap) The track to headworks of Khimti-2 Hydroelectric project of 1.0 Km length is completed connecting from existing road in Dharapani, Ramechhap. Cross-drainage has been provided in three major parts of the road section along with masonry side drain in critical section of the road. Gabion works and Masonry breast wall are provided for slope protection in vulnerable portions of the road section.

Future Plans:

• Side drain in full section of the road is required in order to protect the road from the heavy downpour.
