ALEXANDRIA
Alexandria is the 2nd Capital of Egypt and
considered the main harbor of the “Arab
Republic Of Egypt”.
Total Area is about 3000 km2.
Alexandria city resides at the Mediterranean
sea coast of Egypt ,downstream the path of the
River Nile which represents almost the only
source of fresh water in Egypt.

Name and company6
ALEXANDRIA
- Alexandria is inhabited by more
than 4.5 million capita , reaches
to 6.5 million capita in summer
due to The situation of Alex. as a
summer destination city.

a major obstacle for AWCO
nevertheless the limited resources.
- Alexandria Contains 40 % of
industrial activities in Egypt and
contains two large industrial cities
“Borg el Arab – New Nubaria “.

Name and company7
Alexandria Water company (AWCO)
- In 1968 : Alexandria Water Company became a general authority

Name and company9
Alexandria Water Company Profile
 Service Area:- Whole Alexandria Governorate , Most of Matrouh
Governorate and Part of Behira Governorate .
 AWCO’s effort in the filed of reducing NRW & leak management
started since 1992.
 AWCO was the first company in Egypt to oblige each customer to
install a private water meter for his flat.
 Total number of meters are around 1.4 million.
 Non-Revenue water % = 44 % in 2005 reducing to 35.7 % in 2011
, saving around 89 million m3 in 4 years and 62.5 million EGP .

 The test confirmed the absence in the subdistrict of illegal
connection and background losses (tanks, etc.) during the
period of its implementation.
 The clamp-on ultrasonic flow meter installed at the inlet point
of the subdistrict can accurately measure the minimum flow
entering

 The Non Revenue Water has been calculated as the difference between the
water fed into the pilot area and consumption. The value of NRW
encompasses both apparent (commercial) and real (physical) losses
 The main component of NRW in ARAMA pilot area is represented by
apparent losses, in the following components:
1- Systematic consumption data handling errors
2- Customer metering inaccuracy (in the old meters)
 Reduction of meters inaccuracy and manual meter reading errors (by
improving the internal procedures of the utility) are therefore a priority as
economically more convenient than network rehabilitation
 Considering that private meter errors generally represent an important
part of apparent losses, significant saving can be achieved by selected
meters replacement
