Munda Dam Project Expression of Interest (EOI)

MUNDA DAM PROJECT

IMPORTANT INFORMATION

1. Introduction

Pakistan Water and Power Development Authority (WAPDA) intends to hire the

services of Consultants for Detailed Engineering Design and Praperation of

Tender Documents for Munda Dam Project.

2. Objectives

The project aims at:

Irrigated agriculture development of 6,853 ha (16940 Acres),

Hydropower Installed Capacity 740 MW (Annual Energy 2407 GWh).

Flood Control.

3. Location

Munda Dam site is located on Swat River, about 5 km upstream of existing Munda

Headworks at Abazai near Shabqadar Deri and 37 km north of Peshawar in

Khyber Pakhtoonkhaw province. The dam site is situated approximately at

coordinates 34o 21 N and 71o 32 E.

Figure-1 shows project location map.

4. Catchment Area

The total catchment area of the Swat River basin is 13,650 km2 at the proposed

dam site, lying between latitudes 34020 N to 35056 N longitudes 71020 E to

72050E and is about 137 km long and 110 km wide. The proposed Munda

Reservoir is extended from south to north in a steep gorge of the Swat River.

The Munda Dam site is situated at the downstream end of the mountainous

area of the Swat basin, from which the valley widens forming a fn configuration.

5. Geology

Bedrock of the Munda Dam site is proposed mainly of crystalline schist, party

8/3/2019 EOIMunda

4/12


Soil cover is very limited and the bedrock, apparently not seriously weathered,

is widely exposed. The rock in the surface zone, however, is slacked and show

high water permeability in borehole water test. The foundation has a general

condition that the seepage potential from 25 Lugeon unit up to higher values

over 100 prevails in the zone from zero to 15 m of depth and the medium

seepage not exceeding 25 Lugeon unit in the zone from 15 m to 35. Deeper

than 35 m, the Lugeon values are not more than 5, in the upper part of the

slope for the dam abutment, the slacking of the bedrock deepens, and the

topographic and geologic conditions are poor and less stable in the higher part

above elevation 560 m, the thin limestone layers intercalated in the schist near

the dam site, which strike at nearly right angle to the river channel and are notdeeply karstified, will not cause visible under seepage.

The reservoir area stretches to the area of Permian to Cretaceous metamorphic

rocks with variety of crystalline schists and granite or granitic gneiss. Limestone

is also included in those strata with signs of karst solution at places. The

karstification or the formation of cavities in the limestone is limited within the

depth of several tens of meters as was seen in the drilling of the Sapparelimestone or within a reach of underground circulation of the rain water with

carbon dioxide. As seepage water would have to travel far, there is no

possibility of substantial water loss occurs from the reservoir. Slopes are

generally stable and no large land slide is envisaged.

6. Seismicity

The Project area is located in a high tectonic zone of the Himalayan foothillsand between two major thrust faults. The seismic risk was estimated form the

earthquake record of 2,259 events obtained from an international earthquake

data of USGS. For dam design, a design earthquake acceleration of 0.15g is

proposed.

7. Project Components

The feasibility study of the project was prepared with the technical assistance of

JICA in March 2000. According to the study, the project comprises the following

components.

12 1 Main Dam

12.2. River Diversion and River Outlet

The tunnel type river diversion was designed considering the topography with

steep abutments. At least two river diversion tunnels are required so that the

river outlet facilities can be installed on one of the tunnels while the other

tunnel continues to divert the river flow. The diversion tunnels are 12 m in

diameter, and 975 m and 964 m long, respectively, both being laid out on the

left bank.

The river outlet facilities constructed in the left diversion tunnel will function to

release river water downstream for meeting irrigation and other waterrequirement during reservoir impounding as well as to release reservoir water

to draw down the water level in an emergency case. The river outlet has a

morning glory type intake, a shaft of 4.5 m diameter and 100 m long, and 2

sets of gates.

12.3. Spillway

The combined type spillway consisting of gated spillway and non-gated weir

was laid out on the left abutment to suit the topography. The designed

spillway has 4 sets of gates, each being 15.5 m wide and 18.4 m high, with a

80 m long non-gated overflow weir accompanied with a 60 m wide chuteway,

a flip bucket, and a plunge pool.

12.4. Waterway and Power House

A power intake, an intake gate shaft, a headrace tunnel, a surge tank,

penstock tunnels, open penstock, a surface type powerhouse, and an open

switchyard were laid out on the right abutment. The powerhouse will be of

conventional surface type, and constructed on the right bank of the narrow

gorge of Swat River.

The headrace tunnel diameter was set at 12 m and penstock diameter at 7.4

m based on the optimization study. The restricted orifice type surge tank was

designed, of which the upper and lower chamber diameters are 25 m and 15

m, respectively.

12.5. Re-regulation Weir

8/3/2019 EOIMunda

6/12


The maximum water level in the normal condition and flood water level were

estimated to be EL.381.8 m and EL.372.2 m, respectively.

12.6. Power Station Facilities

The Munda power station is planned as a peaking station with daily peak

duration of 4 hours. The total available output of the power station from the

operating water head (162.5 m) and discharge (505 m3/sec) is 740 MW. The

power station will be provided with four 185 MW units of water turbine

generators.

12.7. Transmission System

A 220 KV double-circuit transmission line, about 35 km long with 2-bundled

rail conductors (494 MCM) will be required between the outdoor switchyard

and the planned New Shahi Bagh substation (main substation for supply to

Peshawar) to connect with the 220 KV network in the area. The New Shahi

Bagh substation needs to be designed taking into account receiving of 740

MW Munda power.

12.8. Irrigation Facilities

Irrigation facilities for the Project were designed as a newly established

system. Layout of the irrigation system would be taken into consideration the

deployment of beneficial farm lands and location of rivers and water courses

so as to apply proposed on-farm development system. A tunnel system at theleft bank area and a lifting system with pump at the right bank area are

selected for the feeder system.

12.9. Environmental Assessment

An Environmental Impact Assessment (EIA) was carried out for the project,

which identified the possible impacts, and proposed mitigation measures, with

the objective to maximize the benefits and minimize the undesirable impacts

on the environment and the surrounding local community. In the feasibility

report 2000, it was concluded that overall the Project is not going to have any

major negative environmental impacts.

Clean Development Mechanism (CDM) projects. An Operational Strategy has

been developed to fulfill the requirements of establishing a Designated

National Authority (DNA) and ensuring transparent, participatory and effective

management of CDM process in the country.

Carbon Credits are applicable in certain cases of hydropower projects, where

a demonstrable reduction in greenhouse gas emissions can be claimed as a

result of the Project.

In order to qualify, a project has to cross a number of barriers; in particular by

providing additionally i.e. measure of the benefits that the project brings thatwould not have been available in its absence and quantifying the benefits in

terms of avoided emissions. Once credits are confirmed, it is necessary to

trade them through one of the Carbon Funds to convert them into a hard

currency revenue stream from the start of the commercial operations.
