Improving Efficiency
• ↑ CAPEX for improving efficiency: i.e. pipe
replacement, installation of VFDs,…but:
• High $ amounts
• Budgetary
constraints
• Approval periods
• Implementation
periods
• Current IT capacity is not used at 100%
• Projects are
not aligned
• Data silos
• Not getting the best
financial return out
of the investments
The Smart City / Smart Water approach
Traditional Approach
Smart Approach
Increased demand met
by building more capitalintensive infrastructure
Increased demand met
by making
infrastructure more
efficient, not larger
Departments operate in
silos with little or no
information sharing
Information sharing
enables coordinated
action and minimized
network disruptions
Tons of data collected
by systems but not used

tools used to optimize
performance
A Smart Water Network is a key component of a Smart City
Why Change How We Operate?
● Total energy consumption of U.S. water utilities is estimated to be 56 billion kWh,
equaling $4 billion annually in operational expenditures1.
● California’s water and wastewater utilities energy consumption comprise 19% of
the total energy usage in that state2.
● Between 5-10 billion Kw/h of power generated in the U.S. is spent in water that is
either leaked or not paid for by customers3.
● The U.S.G.S. estimates that water lost from water distribution systems is 1.7
trillion gallons per year at a national cost of $2.6 billion per year4

Questions
Traditional SCADA Systems
Supervisory Control And Data Acquisition
• Type of industrial control system
Industrial control systems (ICS) are computer controlled
systems that monitor and control industrial processes that exist
in the physical world
SCADA typically are different from other ICS systems by being
large scale processes that can include multiple sites and large
distances
Processes include industrial, infrastructure, and facility based
Infrastructure Processes:
•
•
•
•
Water treatment and distribution
Wastewater collection and treatment
Oil & gas pipelines
Electrical power transmission and distribution
Traditional SCADA Systems
Typical SCADA Subsystems
Human Machine Interface (HMI)
• Processed data is presented to the operator
Supervisory System
• Gathers all required data about the process
Remote Terminal Units (RTUs)
• Connected to the sensors of the process
• Help convert sensor signals to digital data and send data to
supervisory system
Programmable Logic Controllers (PLCs)
• Used as field devices
Communication Infrastructure
• Connects RTUs to supervisory system

Questions
Smart Water SCADA:
“Welcome to the new era of SCADA, and goodbye to the days of basic supervisory
control and data acquisition. Today’s SCADA systems are reaching into most
every aspect of a water utility’s water distribution and treatment operations, for a
true enterprise-wide methodology.
And most every stakeholder in the enterprise can benefit if the utility is ready to
harness his or her SCADA system’s power. All it takes is the time to investigate...”

while breaking down the typical silos that exist within a utility.
Water network management through data collection,
measurement and analysis—ensuring optimal efficiency,
longevity and reliability
Energy and process management to help meet demand,
maximize resources, reduce costs and emissions, and ensure

SCADA + GIS
Display of SCADA on
GIS screens or vice
versa can easily be
accomplished.
Ties static data such
as asset location
with status info in
the SCADA
Provides a key link
between
supervisory
operations and
business decisions
SCADA + ASSET MANAGEMENT
Schneider Electric | Jeff M. Miller | 2014 MWEA & AWWA-MO Joint Annual Meeting | 10:30 Monday March 31st, 2014
21
SCADA + Asset Management
Can drive more data that
managers can use while breaking
down the typical silos that exist
within a utility.
Allows important information to
be shared across departments.
Can help achieve a city’s energy
efficiency goals by monitoring
key assets at each plant.
Key assets could be ones that use
a tremendous amount of energy
such as pumps and blowers.
Dashboards with KPIs listed can
help determine which assets to
focus on.
SCADA + Asset Management
- Des Moines, IA
Their (Des Moines) initial plans were to optimize performance
of assets that are energy hogs (blowers and pumps) but they
discovered that, in the case of four of their 2,000 hp blowers,
just knowing which units were operating most efficiently and
using those units as the primary air movers provided results
that exceeded their initial project goals.
Just understanding what they were already doing well
contributed significant returns. Being able to detect process
deterioration is also of high value, which the KPI dashboard can
alert them to.
This integration has resulted in annual energy savings of
$40,000 at one plant alone.
SCADA + HYDRAULIC MODELING

operation of water distribution
system
By using live SCADA data a
hydraulic model can be
transformed from a planning
tool to a decision making tool
Quick assessment of required
action
Not dependent on specialists
SCADA + Hydraulic Modeling
Pressure Control

•
Reduction in loss of water
Reduced number of new leaks
Less use of energy for pumping
Less CO2 emission
Less wear on pumps
Graphical overview of zones
• Quick reaction
• Correct and qualified reaction
Contingency Planning
Expected savings
• 10% reduction or more in NRW
• ROI in 18 months is common
SCADA + AMR / AMI
Schneider Electric | Jeff M. Miller | 2014 MWEA & AWWA-MO Joint Annual Meeting | 10:30 Monday March 31st, 2014
29
SCADA + AMR / AMI
AMI extends current advanced meter reading (AMR)
technology by providing two way meter communications,
allowing commands to be sent toward the home for
multiple purposes, including “time-of-use” pricing
information, demand-response actions, or remote service
disconnects.
Improved understanding of water consumption and flow
patterns
Increased revenue
(less unaccounted for water)
Reduced meter reading costs
Provides outage detection and management
SCADA + AMR / AMI
Could be accomplished through a performance contract
• Depends on a utility’s existing level of non-revenue water
AWWA Water Audit Form
• Water Supplied
• Authorized Consumption
• Water Losses
• System Data
• Cost Data
• Additional Info (leak detection capabilities, SCADA, etc)
SCADA + LEAK MANAGEMENT
Schneider Electric | Jeff M. Miller | 2014 MWEA & AWWA-MO Joint Annual Meeting | 10:30 Monday March 31st, 2014

SCADA + Leak Management
Reduction of
Non-Revenue Water
Problem: Lost revenue
due to aging
infrastructure and
meter inaccuracies.
Bad public image and
increasing regulation
add stress to the
problem.
Water utilities average
15%-25% non-revenue
water.

You Can’t Manage What You Can’t Measure
The water industry
encourages utilities
to develop and use
KPIs to identify areas
of improvement,
define realistic
targets, design action
plans, and track
improvements over
time.
Smart Water SCADA Benefits
Helps streamline daily operations and maintenance and
improves network water loss management system planning.
Solutions are scalable, providing sustainability solutions for
water utilities of nearly any size.
Water utilities can automatically extract data from different
systems and calculate performance indicators that accurately
and objectively represent water network performance.
Finally, with these benchmarks , the utility can communicate
performance measures in a consistent manner to all
stakeholders.
