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


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.
