Preface
Water in the MEDA region is a crucial issue, with regard to the availability of renew-
able water resources in the MEDA countries most will face even more serious prob-
lems in the management of their limited water resources in the near future. This will
require a lot of efforts to be made for more efficient management of water, in order
to secure the economic and social development of the coming generations.
According to the FAO (2006) the average of renewable water resources in the
MENA region is below the limit of 1000 CM per Capita and Year, for Egypt for
example is this 794 CM, for Algeria und Tunisia 481 CM, for Jordan 180, Yemen
234, and Palestine 100 which are far below the limit of 500 CM that classify these
countries as the most water stressed countries worldwide.
The alarming aspect is the fact that the limited renewable available water resources
development have been decreasing in the last thirty years, between 1974 – 2000 we had
66% decrease for Jordan and 64 % for Yemen, due to the increasing population growth
and the increase of water demands for agriculture, industrial and domestic use. These
figures underline the importance of the topics of this book that shall give help to experts
and decision makers to over come the future water resources problems in the region.
Water reuse plays an important role in water management as the domestic waste-
water streams are mostly independent from dry and wet seasons and can be consid-
ered as a relatively fixed amount of available resource throughout the year.
If we look at the example of wastewater treatment in the western European
countries, where water scarcity is mostly not a major issue, the centralized water
borne sanitation systems have contributed to ensuring public health without doubt.
Their implementation were a major step in improving living conditions in growing
cities about 100 years ago.
However, today we realize that this system is not the best available principle for the
next decades or even centuries especially not for water scarce regions. Reasons are:
● Drinking water is wasted for transportation of faeces and urine, a relatively high
flow is needed only to keep sewers functional
● Central wastewater treatment is more complex and costly than necessary, esp.
high energy costs and is often not where reuse is possible
● Sewerage of centralized systems is very costly in construction, rehabilitation and
maintenance

● Nutrients are only partly removed and lost as fertilizer
● Problems of sludge disposal
Within the last decades, many technologies in the field of wastewater management
such as systems like different sewerage for wastewater collection and hybrid sys-
tem, UASB or products by many companies for treatment were developed for spe-
cial applications and frame conditions that the variety is difficult to overview.
However, wastewater treatment is not just a black box that can be easily copied and
implemented in any case. As every area, town, village has its own properties and
conditions, there is no unique solution possible. Each region, area, town or village
needs a tailor made solution for wastewater management. The systems and tech-
nologies are developed but must be adapted to the local conditions. Wastewater
treatment touches all parts of society that it is very important to consider it from the
beginning in regional planning.
Within the regional planning, the following priorities should be considered from
the beginning:
1. Wastewater flows can be reduced by demand side management. Efficient usage
of water can be achieved such as public awareness for water efficient house
installations and water saving toilets and efficient drip irrigation.
2. Rainwater should be harvested where appropriate and possible.
3. To avoid the dilution of pollutants in the wastewater, heavily polluted industrial
effluents should be treated and reused separately.
4. When selecting the wastewater system, central, communal or decentral solutions
must be considered and compared with dynamic cost comparison.
Based on these considerations, the best option for wastewater collection, treatment
and reuse can be evaluated.
The decision behind the publication of this book came after a successfully con-
ducted conference within the activities of the EU funded EMWater project in
Jordan in autumn 2006..
The EMWater regional conference has had very good response, with more than
150 participants and 60 papers from 17 different countries from the EU – MEDA
region, from Australia and the USA. The best papers presented in the EMWater
regional conference are being published in this book.
The EU funded EMWater Project “Efficient Management of Wastewater, its
Treatment and Reuse in the MEDA Countries” started in May 2003 with 9 dif-
ferent partners from MEDA and the EU. The EMWater project consortium con-
sists of four EU partners – InWEnt Capacity Building International, Germany,
Hamburg University of Technology (TUHH), Germany, Adelphi Research,
Germany and the National Agency for New Technology, Energy & Environment
(ENEA), Italy – and five Mediterranean partners – YILDIZ Technical University,
Turkey, University of Balamand, Lebanon, Lebanese American University,
Lebanon, Al al Bayt University, Jordan and Birzeit University, Palestine
The EMWater project is focusing through its different activities on the aspects
of wastewater treatment and water reuse.
Preface ix
During the last 4-year EMWater project program that conducted in the region,
the following activities have been implemented:-
1 Data collection and evaluation of wastewater situation in the target countries:
Lebanon, Palestine, Jordan and Turkey.
2 Production of public awareness programs in Arabic, Turkish and English.
3 Conduction of Capacity building programs through local, regional and web
based training courses; more than 1300 participants from the region have
been trained.
4 Design and construction of 5 pilot plants for demonstration and research
purposes
5 Elaboration of EMWater guide for wastewater treatment and water reuse
6 Publication of trainer tool kits for experts and trainer who work in the field of
wastewater treatment and water reuse
Some of the authors of this book are covering the aspects of water and sludge reuse and
the positive impact on soil and plants production. The benefit of integrated anaerobic
and aerobic wastewater treatment which reduce energy consumption, operation costs
and increase treatment efficiency, is recommended by other authors as a sustainable
treatment option for the Middle East countries.
Case studies for sustainable sanitation by using constructed wetlands, cost ben-
efit analyses for centralized and decentralized systems to support decision makers,
the benefit of using bio membrane reactors technology to get high performance for
variable wastewater treatment characteristics, were also included in this book.
Other important topics like social and economic aspects of water reuse, the
community participation, culture relation, water value, global climate change and
water scarcity, were included in the book too.
The new recently published WHO Guidelines for safe wastewater use in agricul-
ture were evaluated by other authors who give decision makers practical guidance
how to apply these new guide lines. The pond system as an efficient, natural and
adequate wasterwater technique was also recommended, and finally the aspects of
improved wastewater treatment by using constructed wetlands by applying earth
worms and alternative plants were highlighted by some other authors.
The authors in this book are well known experts in the field of wastewater treat-
ment and water reuse. Through their papers published in this book, we hope that an
essential contribution will be made towards solving the current and future water
stress problems in the MEDA region.
As editors, we want the readers to have a look at the various aspects of waste-
water management and water reuse, to consider innovative technologies as well as
innovative low-tech based on traditional systems of the region and to aim at their
tailor-made solution appropriate for the local situation.
