Introduction<br />
National Water Company awarded in 2008 a<br />
Management Contract to a JV formed by<br />
Acwa Power & Suez Environment<br />
establishing the Jeddah City Business Unit to<br />
provide water <strong>and</strong> waste water services for<br />
the 3,5 M of inhabitants of Jeddah.<br />
JCBU operates a network of 5,500 km of<br />
network for water <strong>and</strong> 1,400 km for waste<br />
water.<br />
30/03/2011 06/03/2012 > SUEZ ENVIRONNEMENT - 3
Context of Jeddah<br />
Operational & Infrastructure<br />
• Water supply of 650 000 m3/day (65 %<br />
through the network <strong>and</strong> 35 % by water<br />
tankers)<br />
• 5.500 km of network (80 % in plastic<br />
pipes), only 5% with an average pressure<br />
of 0.5 Bars<br />
• Lack of sectorization <strong>and</strong> operational data<br />
like flow measurement, pressure,<br />
hydraulic behavior,<br />
Internal Processes & Communication<br />
• Absences of reliable Call Center <strong>and</strong><br />
Operation Center.<br />
• No communication between Operational<br />
<strong>and</strong> Customer Services Departments.<br />
• No process, resources or systems to<br />
follow up leak detection <strong>and</strong> repairs<br />
activities.<br />
06/03/2012 > SUEZ ENVIRONNEMENT - 4
Context of Jeddah<br />
• Supply frequency : 23 days<br />
• Poor quality of service<br />
•35% water supply by water tanks<br />
•Growing population & rapid economic development<br />
•Lack of natural resources <strong>and</strong> high water production cost = desalination<br />
• Insufficient <strong>and</strong> poorly-maintained infrastructure (~ 40% water losses,<br />
2/3 population not connected to sewers)<br />
• Weak <strong>org</strong>anization <strong>and</strong> public discontentment<br />

Advanced Network <strong>Distribution</strong><br />
Solution for Jeddah<br />
Creation <strong>and</strong> <strong>Implementation</strong> of 51 <strong>Distribution</strong> <strong>Zones</strong><br />
• To manage the evolution from rationing to continuous supply<br />
• To operate the network through an advanced system with<br />
pressure control <strong>and</strong> flow measurement linked to the SCADA<br />
• Water balance assessment <strong>and</strong> NRW actions by priorities<br />

<strong>Pressure</strong> Management<br />
• The average flow reduction by DZ is estimated in 2000<br />
m3/d after PRV implementation, around 11 % of the water<br />
dem<strong>and</strong><br />
• 2 systems are being tested going to be tested to optimize<br />
the pressure following the consumption 24/24 to increase<br />
water savings <strong>and</strong> reduce leakage (i2O system & Sofrel<br />

Conclusions<br />
Global offer adapted to changing environments <strong>and</strong> through<br />
different type of contract<br />
Segmentation by Business Solutions, more versatility<br />
Advanced Network <strong>Distribution</strong> Solution implemented in Jeddah,<br />
Quickly identification of the problems <strong>and</strong> tailored solution<br />
decided <strong>and</strong> implemented<br />
OCC & SCADA with the measurement network gives enough<br />
elements to start the DZ project<br />
<strong>Implementation</strong> of DZ on going, 8 finalized by the end of 2011<br />
& 28 by 2012<br />
Quickly improvement on the Operation of the rationing after<br />
the identification of the DZ<br />
<strong>Pressure</strong> reduction allow to save around 10 to 15% of the<br />
daily water supply (1Mm3/day > 100 000 m3/day available<br />
fro other customers)<br />
<strong>Pressure</strong> management shows further reduction of 14 to 20 %<br />
on the daily water supply to the zones.<br />
