Survey Details
The Economist Intelligence Unit conducted a survey of 244 seniorwater utility executives across the ten countries under review.
All respondents hailed from the management function of theirbusinesses, with close to one-half (45%) consisting of C-suiteexecu ves.
Organizations of all sizes were polled: 13% have annual revenue in
excess of US$1bn, while 40% are firms with under US$250m in.
Nearly one-half (48%) are owned by either the state or a localmunicipality; the balance are privately owned, barring 6% which

Increased water stress is a foregone conclusion
For most water utilities, increased water stress by 2030 isa foregone conclusion.
About four in ten executives (39%) polled for this reportthink that, given current trends, national water demandin their countries will outstrip supply by 2030.
.the nature of such stress varies hugely, depending onlocal circumstances.

Increased water productivity is the core
To ensure sufficient supplies, utilities are making wide-ranging productivity improvements—everything from

Investments are rising as well.
Across the ten countries polled, 93% of respondents say
they are increasing their investment in water production
More than one in five (22%) utilities surveyed will increase

Wasteful consumer behavior is largest barrier
Across much of the world, water flows out of taps at almost no cost tothe user.
Nearly half (45%) of utilities—especially in developed markets—seethis as their biggest barrier to progress, while a further 33% believethat tariffs are too low to stimulate reater investment..
In developing countries, a lack of capital for investment tops the list of concerns selected b 41% while worries over climate chan e are close behind (38%).
,right skills, further deepen the challenge.

A far greater focus on demand management is
to build up supply and distribution networks, but muchmore emphasis is now being put on cutting water use.
From both a strategic and technological perspective, new
measures utilities believe will help reduce use.
Such measures are effective: research suggests a 10-15% average drop in usage once a meter is installed.

DMA – District Metering Area
Improving the Network Topology
FROM: Open Water Network System
pipe network. NRW can only be approximated for the entire system.
TO: Zoned Water Network Systems (DMA)
The pipe network is divided into smaller and hydraulically isolated zones whichallow a more accurate and manageable NRW calculation.
es gn cons era on
• Size of the DMA (number of connections, pipe length, etc.)
• Network configuration (number of flow meters, number of valves)
• Topographic features (urban, rural, ground level variations, etc.)• Data Loggers (flows, pressure, legitimate night flows, sonar, etc.)
• Establishing and calibrating a hydrological flow model
