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

Page 19: Overview of Singapore Water Management...6 sea From sourcing, collection, purification and supply of drinking water, to treatment of used water and turning it into NEWater, drainage

19

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

Page 20: Overview of Singapore Water Management...6 sea From sourcing, collection, purification and supply of drinking water, to treatment of used water and turning it into NEWater, drainage

20

Accurate Metering

100 % metering for usage and billing

Type of meters in use

• Electromagnetic meters at waterworks

• Class C volumetric meters at

households

• Compound meters to capture both

low and high flows in non-domestic

premises

Domestic Meter

Compound Meter

Electromagnetic meter

15 mm meter

(Replace every 15 yrs

or > 4,000 m3)

Compound meter

(Replace every 2-7 yrs)
