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)
