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
2
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:
