Electricity production utilizes over 40% of all daily
freshwater withdrawals
Water and wastewater utilities account for 30-40% of
the electricity used by mid-sized cities

Information is Power…
Information Communication Technologies (ICT)
provide the information to save power.
ICT enables the Owner/Manager:
• Be more knowledgeable about their system
operation; Knowledge is power.
• Have the information to make smart decisions
that save time, effort, and money; ICT enables
efficiency

Metering Technology Progression
Manual Read (Flip the lid)
“Little” to no technology
Read hundreds per day (300-
500) (very dependent on
situations and walking pace)
Remote (outside) Reader
Write down reading or
punch in handheld device
Will have to upgrade soon,
no longer in production
Metering Technology Progression
Touch Pad “Walk by”
Removes data entry errors
(when programmed correctly)
Data stored in handheld
device
Radio Read “Drive By”
Radio frequency to deliver
meter reading to Vehicle
Ability to read thousands
of meters a day.
Eliminates goat hazards
System of endpoints,
repeaters, collectors,
backhaul, server, and
software.
Radio frequency to deliver
meter reading
Numerous suppliers and
technologies in the market
Ability to read service area
meter population every day

Water Treatment Chemical optimization software provides real time monitoring
and chemical dosing to stabilize, optimize chemical use, resulting in more
efficient processes (clarification & filtration)
Example: Clearlogx
How:
• Automatically continuously controls the feed of specialty chemicals used in water
treatment in order to maintain optimized chemical
• PLC, instrumentation, control logic
• Easily retrofitted
• Real-time monitoring and optimization
• Optimizes pH control and particle charge
Treatment Process Optimization and Analytics
Wastewater specific software aeration process performance optimizer providing
real time monitoring and other process parameters to ensure optimal treatment.
Example: XYLEM (OSCAR)
How:
• Software, Xylem instrumentation (probes & sensors)
• Real time monitoring of influent, in-basin, and effluent parameters
• Control of WAS rates to optimize Solids Retention Time (SRT), DO/NH4 control for
energy savings
• Automated Reports, data analysis
Treatment Process Optimization and Analytics
Membrane Bioreactor specific software provides real time monitoring of
membrane process parameters to continually optimize performance, membrane
membrane longevity, and energy use.
Example: GE InSight – Knowledge Management Platform
How:
• Data analytics monitoring flow, basin level, specific flux, permeability, transmembrane
pressure
• Quarterly reports provided to Owner/Operator
• Recommendations for improved energy savings, chemical savings, optimized
performance

Applied at Water Treatment Plants and Wastewater Plants to monitor energy use
(kWh) and demand (kW)
Can be stand alone system or incorporated in plant System Control and Data
Acquisition (SCADA) system
Advantages:
• Typically fully developed and ready to install
• Client customized based application
• Real-time reporting
• Successfully applied at 120+ WWTPs

Reporting System
Demand Response
encourages reductions in
electricity use during times of
peak demand, high wholesale
prices, or grid emergencies
• Customers temporarily shed or shift loads in response to a request by a
utility or based on market price conditions
• Useful in controlling overall energy procurement costs and avoiding
emergencies (blackouts)
• Goes beyond simple energy efficiency and energy reduction measures
to temporarily curtail or shift load to different times
Demand Response
DR Program and What It’s Worth
*A typical season has 1 – 6 events annually (estimate)
• Demand Response $48-$60 per year for every kW you can reduce (1MW
is $60,000)
• AutoDR $200 per kW of additional incentives to automate reduction (1
MW is $200,000)
