17th Oct 2008, Chennai Earlier Scenario –Issues & Challenges • Old Water distribution pipelines • Non availability of maps/layouts • Non availability of asset repository • Information stored “skilled minds” • No information on water supply & demand • Limited use Topographical maps • Designs - Thumb rule/traditional method • No concept –pressure Management/DMA • Meters- what / How ???
17th Oct 2008, Chennai THEME
To reduce the Non Revenue Water for
• Raw water
• Clarified water
• Potable Water (Rising Mains and Distribution Network)
To the world bench mark levels:
Singapore (4 %)
17th Oct 2008, Chennai Non-Revenue Water
Water loss occurs in all distribution systems - only the volume of loss varies.
• How much water is being lost?
• Where is it being lost from?
• Why is it being lost?
• What strategies can be introduced to reduce losses and improve performance?
• How can we maintain the strategy and sustain the achievements gained?

District Metering Area or DMA is defined as an area with a metered source of water and closed boundaries.
DMA: Condition for DMA: • 7 command area tower wise • network area must be Segregated for creating DMA “hydraulically segregated”
• command area wise DMA • operable valves to ensure created –Field studies-GIS complete opening & closing of water • 74 DMA created • all water supply source is •DMA wise Monthly NRW metered Assessment /leakage/complaints/consumpt ion pattern • DMA wise billing Revenue assessment monthly 17th Oct 2008, Chennai Impl. of District Metering Area (DMA) for 24x7 supply For implementation of 24 x 7 the entire CH area was to be converted to a DMA with hydraulically closed boundaries.
Condition for DMA: Boundary Valve • network area must be “hydraulically Mete segregated” r
• operable valves to DMA ensure only from DMA metered inlets.

Step test is conducted at night time when it is assumed that the consumption is minimum.
Objective - To break the distribution network into smaller section and determine sectional NRW and identify sources of losses & leakages. 17th Oct 2008, Chennai Leak detection equipment Step test curve – CH area discreet meter data

17th Oct 2008, Chennai Drink straight from tap, thanks to Tata's water utility By Joydeep Gupta (Visiting Delegate with World Bank Team on 18th Sept.’08) Indo-Asian News Service
QUOTE Jamshedpur, Sep 28 (IANS)
This could be India's only city where you can drink water straight from the tap, thanks to the local utility Ask oil mill owner Manoj Singh, who has paid Rs.10,500 for a connection - a month's income - but doesn't regret a single paisa.
Singh has found no cause for complaint since his working class neighbourhood Shastri Nagar, just outside the township, was connected to the JUSCO network last November.
"Yes, I paid a lot of money for the connection," Manoj Singh told IANS. "But it has been worth it. Now the women do not have to go and queue up for hours to fetch drinking water. We get clean water in our taps, 24 hours a day. Where else in this country will you get that?"

Major Components of NRW are
– Leakage
– Illegal Connections
– Metering Errors
