16 Integrated Network Management System
Good Quality Network & Efficient Management Leakage Control
Strict Legislation Good Customer Service – Customer Reliability & Relationship Quality Management
Accurate Metering OUTCOME Low UFW
17 Good Quality Network & Efficient Management
New Network • Good planning & design – sizing of pipes, location of valves, alternate supplies, etc •Strict supervision & control on workmanship • Use Good quality / corrosion resistant material – Connections : Copper – Mains (100 – 300 mm) : cement-lined DI – ( ≥ 700 mm) : cement-lined steel
Existing network
• Servicing and maintenance of valves / hydrants
• Mains Renewal Programme - Unlined CI mains and GI connections (in 80s / 90s) - Old problematic CI Mains (2000 – 2004) - Asbestos Cement Mains (2003 – 2008)
• Ongoing pipe replacement programme
18 Active Leakage Control Dynamic Leak Detection Programme – Divide Singapore into ~ 300 zones – Frequency of checks based on age/material type of mains & leak history – Use of advanced leak detection equipt including leak localisers – Cover 10 – 20 km length of pipes / day
Dry weather flow by other PUB in charge of drains and waterways
19 Accurate Metering 100 % metering for usage and billing Type of meters in use • Electromagnetic meters at waterworks • Class C volumetric meters at households Electromagnetic meter Domestic Meter • Compound meters to capture both low and high flows in non-domestic premises
15 mm meter (Replace every 15 yrs or > 4,000 m3)
Compound meter Compound Meter (Replace every 2-7 yrs)
