2 Executive Summary The Monthly Progress Report is prepared for providing information about the progress of Sano Milti Khola Hydropower Project, Ramechhap (3 MW). It will contain the information about the project activities and achievement of the preceding month along with the work plan for the particular month. This report will be issued in the first week of every month. Major project activities will be highlighted.

3 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 E to E and N to 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. 2.0 Project Development Milestones S No Date Milestone /04/28 BS Survey License Issued in the name of Mr Ram Bdr Tamang /03/07 BS DoED extended the Date of Survey License of 3000 kw in the name of Sano Milti Khola Hydropower Pvt.

4 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.

10 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 has been completed but the kulo maintenance at chainage 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.

The remaining chainage for gabion construction is at chainage At it is also in stage of completion. Previously we have decided to construct the gabion at chainage 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. Figure 12: powerhouse site survey
