Sano Milti Khola Hydropower Project, Fulasi VDC, Ramechhap
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.
