Good Quality Network & Efficient ManagementNew 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
• Ongoing pipe replacement programme
YEAR LENGTH (Km) COST (Mil) REPLACEMENT WORKS
1983 - 1993 181 29 Unlined CI pipes with Cement-Lined DI pipes
1983-1993 68 27 Unlined GI pipes with stainless steel/copper pipes
2000-2005 280 87Old & problematic CI pipes with Cement-lined DI Pipes
2003-2008 120 20 AC pipes with Cement-lined DI pipes
15
Reducing metering inaccuracies
• Monthly drop tests to ascertain the accuracies of waterworks output meters
• Purchase of accurate, good quality meters• Routine Maintenance and Replacement of meters• Computerized billing system (I&R in billing to flag
out meter stop or faults for replacement)• Use of compound meters to capture low flows
Compound Meter
15 mm meter (Replace every 15 yrs or > 4,000 m3)
Compound meter (Replace every 2-7 yrs)
Meter Inaccuracies and Data Handling Errors
Avoiding Data Handling ErrorsSP check readers for implausible readings flagged by billing system before release for billing

Active Leakage Control1. Annual Leak Detection Programme (300 sub-regions)
Leak Noise Loggers Day Survey Check for leaks 2-3 times a year especially in leak prone areas Cover 10 – 20 km length of pipes / day
2. Leak Detection Network Monitoring and Alert System (40 Sites)

Smart Water Grid - Real-time Monitoring of Water Distribution Network
Customised Multi-parameter probe
Since 2008, research project, Waterwise, an infrastructural system of 300 probes and software :1.Low cost wireless sensor network with high rate of data collection2.Integration of network parameters on single platform3.Potential to detect pipe burst through live data
Customised probe to measures flow, acoustics, pH, Oxidation-Reduction Potential (ORP) and electrical conductivity
•Software Suite
• Operate with battery and solar panel

3 Different Combinations
a) WQPA Probe- Water quality: pH, ORP,
fDOM, conductivity, turbidity- Pressure - Acoustics
b) FPA Probe- Flow- Pressure- Acoustics
c) PA Probe-Pressure -Acoustics
*Type of probe is determined by TEVA-SPOT software, human expertise and ground constraints.

• 3Ps – community driven programme
– Grassroots leaders distribute FOC Water Saving Kits
– DIY and adopt good water saving habits (e.g. washing machines, shorter shower)
• Mobile exhibitions at grassroots events
• Door to door visit to assist in installation of WSDs
• Can save up to 5% of monthly water consumption
• By 2006 - all 84 constituencies launched
• More than 910,000 water saving kits distributed & about 40% households installed
• Started in 2007
• Installation of water saving devices at high consumers

Water Efficiency Labelling Scheme (WELS)Water Efficiency Labelling Scheme (WELS)
Objective of WELSTo provide consumers with information on water consumption & efficiency of products which they can factor into their purchasing decisions & thus make more well-informed choices
WELS rate products in terms of water efficiency
1 tick for Good rating, 2 ticks for Very Good rating and 3 ticks for Excellent rating
Voluntary WELS launched on 31 Oct 06
To enhance WELS, PUB mandated it through the Mandatory WELS (MWELS) from 1 Jul 09

• Launched in Mar 2013
• Objective: To enable an organisation to take a systematic approach to achieve continual improvement of water efficiency and to develop and implement water saving measures
• Specifies requirements that contribute to water efficiency:
– Leadership & commitment, water usage, monitoring, measurement, documentation and reporting, design and procurement practices for equipment, systems, processes and personnel
• Facilitate organisations to prepare their WEMP

• PUB encourages substitution of potable water with NEWater, rainwater and sea water
• NEWater :o Frees up potable water for other useso Quality suitable for process use
(UPW), boilers, laundry, air-con cooling towers, toilet flushing, general washing
o Lower price - ($1.22 compared to $1.52)
• Rainwater Harvesting allowedo To consult PUB for any rainwater
collection systemo To comply with NEA’s requirements
on mosquito prevention
Replace: Substitution with other sources of water
