2. Asia (West)
2.0 Introduction
Most of the countries of the western Asia region lie in the arid to semi arid
zones and are considered as countries with scarce water resources. With few
exceptions, the per capita share of water for all purposes are less than 1000
m3/capita/year which drops to less than 200 in some countries. Associated with
that is the predominant dry and desert ecology which has a profound impact on
water consumption, human settlement and socio-economic development of the
region. This, of course, will have a significant effect on the volume of per
capita production of wastewater and its physical, chemical and biological
characteristics.
In terms of their approach to wastewater and stormwater management, it is
useful to characterize these countries with respect to their socio-economical
development and standard of living. They range from oil producing countries
which enjoy growth and prosperity to poor countries; some of them being among
the least developed countries. In spite of that, most countries share common
problems such as high population growth, rapid urbanization and severe water
shortages.
In view of the above and based on their health status and their water supply
and sanitation services, the countries of this region can be classified under
three groups. Group 1 includes Egypt, Syria, Iraq, Yemen and the Palestinian
territories; Group 2 includes Jordan, Oman and Bahrain; and Group 3 includes
Saudi Arabia, Kuwait, Qatar and United Arab Emirates (UAE). This classification
is based mainly on sanitation services provided to their communities and the
level of treatment facilities. It coincides also with standards of living and
Gross National Product (GNP). The latter affects to a high degree planning and
management of wastewater collection and treatment.
In the last 30 years, the region has witnessed a rapid urbanization with unprecedented
growth in their cities due to high rate of population growth and the large-scale
migration form rural to urban areas. The population pressure has put a severe
load on city services and has stretched city resources to a limit where they
could not adequately respond to demands. As a result city authorities were unable
to provide the necessary infra-structure and basic services specially for secondary
cities. Their priority has been basically in providing residences with water
supply whereas the provision of sewage and stormwater scheme has been given
second priority. The exception, of course, are the very rich oil producing countries.
