1 GENERAL
1.1 Introduction
Ghatte Khola Small Hydroelectric Project with installed capacity of 5000 kW, being
constructed by MANAKAMANA ENGINEERING HYDROPOWER COMPANY (P) LTD.,
is in the preliminary phase of construction. Construction site of this project is at the Ghatte
Khola, Marbu‐VDC, Dolakha, which is a tributary of Khare River. This is a run‐off‐river
scheme with orifice side intake. The proposed headworks site is located on the left bank of Ghatte
Khola about 100 m downstream from the confluence of Thado Khola and Ghatte Khola at an
elevation of 1906 masl in Marbu VDC-7. Similarly, the powerhouse site is on the left bank of
Ghatte Khola around 125m upstream of the confluence of Khare Khola and Ghatte Khola in the
same VDC at an elevation of about 1585 masl. Geographically, the project is located in between
86°17′00″ N to 86°18′35″ N Latitudes and 27°46′25″ N to 27°47′14″ N Longitudes.
Water will enter into the system through orifice side intake on the left bank of the river.
Diversion weir is of non‐regulated type, with Orifice type intake & one under‐sluice on the
left bank. Water will be carried to the 32m. long double chamber desanding basin through
30 m long power canal having 7m long spillway. Water is conveyed through a 2234m long
steel headrace pipe having 1300mm diameter and 1015m long steel penstock pipe. Circular
Steel Surge Tank of diameter 5m is used to regulate the surge. There are two numbers of pelton
tur bine s each of installed capacity 2500 kW. A 14.5 km long 33kV transmission line will
feed generated power from the Powerhouse (switchyard) to Singati substation.
1.2 Work Nature
Construction work comprises of construction of access road to Headworks and Powerhouse, civil
works at headworks, headrace alignment, penstock and powerhouse area, fabrication and
erection of steel pipe for headrace and penstock pipe, installation and commissioning of
electromechanical equipment in powerhouse, switchyard and Singati substation, erection of
transmission line and other related works.
Sakurapower/Biruwa/Divyajyoti J.V. has been selected for the construction of all civil works.
North Hydro and Engineering Pvt. Ltd. is responsible for all Hydromechanical works and Hydro
Equipment Services Pvt. Ltd. is awarded electromechanical installation work. Consulting and
construction supervision has been awarded to TAC Hydro Engineers Pvt. Ltd.
17 km. of Motorable track goes from Singati to Marbu (Powerhouse site). Singati is connected
to Charikot (District Headquater) by 47 km. good gravel road. 450 m access road to Powerhouse
Consulting Services and Construction Supervision of Ghatte Khola SHP Progress Report September2018
TAC Hydro Engineers Pvt. Ltd. b
has been constructed to reach the Powerhouse and 500 m to reach Headworks along Ghatte khola.
The overall length of track opening for waterway alignment is around 2234 m. At present full
loaded truck can reach to the Surge Tank area and access road towards Powerhouse and
Headworks.
1.3 Report Setup
TAC Hydro was responsible for carrying out the detailed design of the project. In addition, it has
been awarded the consulting services for the engineering supervision of all the construction works
going on at site including managerial activities at Kathmandu office.
This is Monthly Progress Report for the month of September 2018, which consists of an account
of construction activities of civil structures, hydro mechanical components, electromechanical
equipment, transmission line and project infrastructures carried out in the past month, major
problems arisen, deviations from the original working schedule and the catch‐up plans,
photographs of progresses made in the last months and other relevant details as per the activities
being carried out.
This report includes the following Annexes:
List of personnel of the Employer, the Consultant and the Contractor are given in Annex–
A. Progress Sheets are given in Annex–B. Deviations in Time Schedule is presented in
Annex–C and photographs are presented in Annex‐D.
