Emergency sanitation in urban settings.
Sewage disposal: the problem of a town of two million
inhabitants, Basrah - Iraq.
Robert Mardini, Civil Engineer, ICRC Water and Habitat Department, (presented

Introduction
Today most of the Iraqi population outside the big towns of Baghdad, Mosul and Kirkuk
have to live with insufficient quantities of drinking water and what they have is of low
quality. Sanitation and public health remain precarious as a result of the situation which
has prevailed since 1991.
Since the second Gulf war, the drinking water situation (which in Iraq is de-pendant on
highly sophisticated water treatment and pumping facilities) has been severely affected by
the shortage of electricity, logistics, management and manpower, consumables and spare
parts. Furthermore the insufficient available capacity, the ageing networks and, lately, the
severe drought (and resultant low river levels, combined with higher pollution and
salinity) have made these years particularly difficult ones.
The problem
The Tigris and Euphrates not only supply most of the country with raw water, but also
collect all the wastewater rejected.
Many crucial sewage lifting stations in Basrah, the second most inhabited town of Iraq,
were stopped after the Gulf war. Furthermore, sewage networks were connected, as for
most of the towns of the country, to storm water networks. This adverse combination
made most of the poorest urban areas prone to severe flooding.
The ICRC response
Since 1995, the ICRC embarked on a rehabilitation programme which mainly included
installation of new pumping equipment for 18 lifting stations. A total pumping capacity of
1.5 MW has been installed. Today the ICRC technicians are following-up these stations.
Since the sewage evacuation is fully dependent on power supply, special attention has
been given to the deteriorating electric-ity situation. Recently, the ICRC assisted the
water and sewage authorities in installing six new generators issuing from SCR-986 for
the sewage network, which corresponds to a total installation of 3'300 kVA of backup
power.
Lessons learnt
Through this programme, ICRC engineers and technicians realised that emer-gency
sanitation situations for a town of two million can be addressed only if the following
prerequisites are met:
• Availability of technical expertise to grant a sound and comprehensive sur-vey.
A problem analysis and accurate damage assessment of sewage infrastructures should be performed. Relevant solutions should be proposed with
a realistic plan of action.

• Good relations with the water and sewage authorities are built in order to
establish the right priorities.
• Appropriate safety measures are deployed to ensure perfect working conditions in situ: avoid sewage gases through good ventilation and develop
measures to protect workers.
• Availability of qualified HR to implement the rehabilitation programme:
technicians, welders, mechanics, and electricians. Project managers should
continuously follow-up the implementation to ensure that all safety measures are respected.
• Availability of funds and efficient logistics are in place: most of the time,
costly and heavy equipment must be purchased from abroad.
Conclusions
Nowadays, most of the Water and Sewage treatment services in Iraq are in a very poor
condition. Not only has the productivity been severely reduced, but also the available
capacity is more and more unpredictable. The fact that a ser-vice is available today does
not mean that it will available be tomorrow. Imbal-ance between input and deterioration
continue to persist. In this situation the best the ICRC and other humanitarian agencies
working in the water and sani-tation field can do is to stabilise the degradation.
Although specific interventions can positively affect the water and sewage ser-vices, or
avoid a disaster as seen in Basrah, one should be aware that it is very difficult to
substitute for the economy of what was one of the richest oil-producing countries in the
world until 1990.
It is important to stress that the ICRC's programme is only dealing with the tip of the
iceberg. All it can do is prop up a system which really needs costly reha-bilitation, proper
maintenance and long-term investment.
It would be impossible to assess the social benefits of the ICRC's Water and Sanitation
achievements in Iraq. However, we believe that some risks endan-gering public health
have been significantly reduced, in specific locations such as Basrah town, where
evacuation of wastewater has been notably improved through the refurbishment of a
number of key sewage pumping stations.
The work that the ICRC has been doing over the past six years, to alleviate the most
problematic deficiencies in the Water and Sanitation field, has to continue on a larger
scale, involving co-ordination with all the inter linked sectors.
