Do we need to increase efficiency?
The total energy consumption of US water utilities is
estimated to be 56 billion kWh equating to $4 billion annually
in OPEX (EPA)
Between 5-10 billion Kw/h of power generated in the US is
spent in water that is either leaked or not paid for by
customers (AwwA)
In developing countries, about 45 million cubic meters are lost
daily through water leakage in the distribution networks —
enough to serve nearly 200 million people (WB).
Energy prices increase at a faster rate than water tariffs
meaning reduced margins for water utilities.


Framework: Improving efficiency
↑ CAPEX for improving efficiency: i.e. pipe
replacement, installation of VSP,… Fine, but:

• High amounts • Approval periods
• Budgetary • Implementation
constraints periods

Current IT capacity is not used at a 100%

• Projects are not • Not getting the best
aligned out of the
• Data silos investments


Smart Water Networks solutions improve the efficiency,
longevity, and reliability of the underlying physical water
network by better measuring, collecting, analyzing, and
acting upon a wide range of network events.

More Better Accurate Smarter


SWN: Fundamentals
Smart Water Network’s fundamentals - The 3 I’s:
Information: Realizing your full potential - SWN makes use of
information that you might not know you have
Integration: Make the best of your investments - SWN are
able to make the best of the current IT installed base: your
current investments
Innovation: The constant future – SWN are flexible enough
to take over the utility’s challenges as they come.

Optimization of the existing infrastructure and resources

Business
Improved decision making
Streamlining OPEX and reduction / better planning of CAPEX
needs
Better ROI (existing investments)


Example 1 – Belo Horizonte - Brazil
- Utility Name: Copasa
- 12.1 million people served (5.6 Belo Horizonte) - Improved response on
- Over 40000 km of distribution pipes outage events
- (↓14% outage times)
14%
SCADA Maintenance
- Improved maintenance
policies
Operational data
- (↓33% repair times)
33%

- Improved network control
Data
Maintenance
Real time data
Simulated data
Predicted data
- Improved planning

GIS
Hydraulic Model - Improved public image

Geodata - Increased ROI on all these
investments


Example 2 – Qatar’s Water & Electricity Corporation
- Utility Name : Kahramaa - NRW is the result of a
- 1,4 million people served water balance that takes

Example 3 – Service level compliance
25 Pa. Code § 109.708. Planned service interruptions: The public water supplier shall give reasonable
notice to the affected customers prior to a planned service interruption affecting quantity or quality of
the water delivered to the customer. If the interruption is scheduled to exceed 8 hours and affect 15 or
more service connections the water supplier shall also notify the Department.

52 Pa. Code 67.1 (b) All electric, gas, water, and telephone utilities shall notify the Commission when
2,500 or 5.0%, whichever is less, of their total customers have an unscheduled service interruption in
a single incident for six or more projected consecutive hours.

Conclusions
SWN solutions complements CAPEX

GIS as centric system to integrate and display utility key
information coming from different IT platforms

Planned implementation is key: Remember the 3 I’s

Your utility already has some of the tools – Use them!

You will get benefits and features not available otherwise

Systems integration provides both operational and business
management oriented benefits

Better ROI by maximizing your existing IT systems


Let’s get smart because…

…there is no
substitute for water
