SECTION 6:

TERMS OF REFERENCE

1. Introduction

Islamabad city is the Capital of Pakistan whereas; the Rawalpindi is its neighbouring city.

The population of thickly populated twin cities of Islamabad & Rawalpindi has increased

drastically during last two decades due to rapid urbanization. Population of Islamabad

city (about 0.81 million) and of Rawalpindi (about 1.41 million) as per census-1998, have

now increased to 2.00 million and 2.875 million, respectively as per Census-2017 i.e.

doubled the population during the last about twenty years. The major municipal

stakeholders are Capital Development Authority (CDA)-Islamabad, Metropolitan

Corporation Islamabad (MCI) and Rawalpindi Development Authority (RDA) who would

be the joint beneficiaries of the water conduction project.

Traditional sources of water supply within these municipal limits are a mix of both

surface and groundwater supplies. The reliance on groundwater pumping has seen

unmitigated increase that has in recent decades dwindled the aquifer levels. CDA/MCI

and RDA are spending huge amount per annum for production of water from ground

water and surface water sources of Simly, Rawal and Khanpur Dams, apart from frequent

breakdown of pumping machinery and other Tube-wells components. The need for a new

and expandable water source had been recognized since the turn of the millennium to

reconcile the municipal demand for water use. Hence, it is planned to induct surface water

from Tarbela Dam Reservoir, from where raw water will be pumped to the proposed site

of Water Treatment Plant (WTP), where the provision will be made for treatment of raw

water and treated water will be transmitted under gravity through transmission mains

having length of about 45 km to water service reservoirs for Islamabad and Rawalpindi.

The previously conducted Feasibility Study (year 2005-2009) had seen several revisions

to the raw water abstraction and treatment mechanisms with the final consensus resting

on the draw-off arrangement from Tarbela reservoir through a non-invasive lakeshore

environment. The Siran Pocket of Tarbela Dam Reservoir had been selected as the source

based on several factors related to topography, stability of intake mechanism, route

hydraulics (pumping heads), head losses in water transmission and required residual head

etc.

The feasibility study had concluded with recommendations for a three-phased

development plan towards a maximum raw water withdrawal potential of 655 MGD by

Page 2: TORs- Consultancy Services for Bulk Water Supply from ...6(&7,21 7(506 2) 5()(5(1&( ,qwurgxfwlrq ,vodpdedg flw\ lv wkh &dslwdo ri 3dnlvwdq zkhuhdv wkh 5dzdoslqgl lv lwv qhljkerxulqj

the year 2050. The first phase constitution involved transmission of 200 MGD of water

over a 05 years construction timeline.

Besides exploring additional sources for water supply, the CDA also intends to prepare Water

and Wastewater Master Plans for the Islamabad Capital Territory (ICT) region as it is

imperative to audit / asses the conditions of existing water supply and wastewater system and

improve the network either by refurbishment or redesigning and reconstruction or by

placement of an entirely new system with right sized pipelines which deemed fit. Hence, this

study / project is envisaged to arrive at a most logical and economical solution as well.

The scope of services has been divided into following assignments:
