Sano Milti Khola Hydropower Project, Fulasi VDC, Ramechhap
1.0 Background
The Sano Milti Khola Small Hydroelectric Project (3 MW) is run-off-river type hydropower
project proposed along the Sano Milti Khola in Ramechhap and Dolkha District of Janakpur
Zone. The project area lies within Fulasi VDC of Ramechhap district and Melung VDC of
Dolkha District. Sano Milti Khola Hydropower Ltd. holds the survey license for this project. The
boundary co-ordinates of the project are 86° 02’ 55” E to 86° 04’ 33” E and 27° 29’ 36” N to 27°
30’ 17” N.
Sano Milti Khola Hydroelectric Project has been promoted by SM Investment Ltd (SMI). SMI is
basically a collective effort of Nepalese in South Korea to invest in Sano Milti Khola Small
Hydroelectric Project.

3.0 Project Description
3.1 Location & Access
The project site is about 175 km away from Kathmandu, the capital city of Nepal. Manthali, the
nearest trade center or town is about 22 km away towards south from the project site. Another
nearest town is Charikot which is about 37 km away towards north. The powerhouse site of the
project is 3 km far from the Milti Dobhan accessible by the graveled road Charikot – Kirnetar –
Manthali Road. The proposed intake site is located on Milti Khola at about 6 km upstream from
the confluence of Milti Khola and Tamakoshi River at the boundary of Melun and Phulasi VDC.
The forebay location at Aimantar Village can be reached by constructing about 4.5 km road
section from Milti Dobhan. Similarly, the headworks site can be made accessible by excavating
about 3 km long track along the Milti Khola from the Milti Dobhan.

4.0 Construction Schedule:
5. Project Progress
5.1 Coordination with Department of Forest and Ministry of Energy
Documents for tree cutting and land leasing have been forwarded to the cabinet which will be
approved and forwarded for final agreement with the Department of Forest.
5.2 Meeting with the Banks
The Due Diligence Audit of the project has been requested by the bank. Thereby we are
collecting proposals from the prequalified consultants for finalization of the DDA.
5.3 Meeting with the Electromechanical Suppliers
The proposals of the suppliers are under evaluation for necessary amendment with close
coordination with our Technical Consultants.
5.4 Joint Survey/Investigation of Headrace Section
Based on the detail joint survey/investigation of the headrace section, analysis and necessary
medication of the detail design are being finalized by our consultants.
5.5 Work Progress at the Site:
1. The maintenance of kulo at chainage 2+900 has been completed but the kulo
maintenance at chainage 2+800 is still remaining. The maintenance of kulo was hand
over to the local people on contract. The contract was made and agreed to complete the
work at 20,000 rupees. Out of 20,000, 15,000 have already been given to the responsible
person named Bikram of bagarbese.

2. The construction of gabion is nearly in a stage of completion. The remaining chainage for
gabion construction is at chainage 3+375 – 3+400. At it is also in stage of completion.
Previously we have decided to construct the gabion at chainage 3+500 but we have
postponed the construction of gabion at this chainage for next year(if necessary).
3. The survey of penstock alignment and power house is going to be started from
2073/10/18. And it will be completed approximately after 3-4 days.
