Diversified Utilities Map Sherman • 38,319 Manual Meters • 3.5 Billion Gallons of Water Metered Annually • $18M revenue from water consumption • Annual Meter Reader Salary $800,000 (22 meter readers) • Data Entry Operators Annual Salary $250,000 (5 operators) • Transportation $117,000 (9 vehicles) • CHALLENGES: • Topography • Distance • Alleys/backyards • Hazards Tyler Dallas-Ft Worth AUSTIN HOUSTON San Antonio
Meter Reading Hazards @ TXUG (OTSH) Biohazard along meter route Meter Reader
Meter Reading Hazards @ TXUG (OTSH) • Dogs, Electric Fences, Guns…. • Attempted Robbery and Shooting of a meter reader in Lakeland, FL: Aug, 2009 • Homeowner opened fire on meter reader, Dallas, TX: 2009 • “The Rottweiler doesn't bite”!
Manual Metering Drawbacks • Laborious (back injuries, trips, falls) • Transcription Errors • Biological and Physical Hazards • High O&M (labor, gas, disputes) • No consumption history • Cannot detect customer leaks • Water Theft Undeterred • High meter reader turnover

Benefits of AMR Quick (data acquired remotely during drive by-5 days vs 4 hrs) Meter data communicated by Radio Frequency—no manual meter reading No need to access the meter box during routine drive by, except in unique situations Lower O&M (labor and disputes) 1 hr Consumption history can be extracted to respond to disputes Can detect customer leaks and help identify water theft Lower meter reader turnover Streamline high bill investigations
Automatic RF Meters Quick Remote Safe Accurate Automated 1 hr Consumption History + Vandal & Leak Alerts ANTENNA RADIO BATTERIES IMPELLER
RF used for everything else, why not for AMR Technologies that depend on radio waves: • AM and FM radio broadcasts • Cordless phones • Garage door openers • Radio-controlled toys • Television broadcasts • Cell phones • GPS receivers • Satellite communications • Police radios • Wireless clocks • Radar and microwave ovens • Communication and navigation satellites • Modern aviation • Wireless Internet access • Radio waves are electromagnetic, part of the light spectrum and travel at a speed of 186,282 miles per second—the speed of light Guglielmo Marconi built the 1st Radio Transmitter in 1895
Automatic Meters (win-win situation) Promotes Water Conservation & Remote Secure Data Acquisition Remote Access 5.5 month consumption history stored in the meter for dispute resolution
Benefits of AMR • Quick (data acquired remotely during drive by-5 days vs 4 hrs) • Meter data communicated by Radio Frequency—no manual meter reading • No need to access the meter box during routine drive by, except in unique situations • Lower O&M (labor and disputes) • 1 hr Consumption history can be extracted to respond to disputes • Can detect customer leaks and help identify water theft • Lower meter reader turnover • Streamline high bill investigations
Desired AMR Features • Read remotely under submerged conditions • Integrate continuous leak detection and retrievable consumption history • Use vandal deterrent technologies in unlicensed frequency • Be one-piece, integrated unit with no exposed wiring to look similar to a manual meter • Fixed network AMI preferred, but Mobile AMR considered in analysis
Technologies Evaluated Four AMR Technologies • 1. Walk-by with Handheld • 2. Drive-by with Laptop • 3. AMR: One way Fixed network • Periodic Data Transmission one way from Meter to SWWC • 4. AMI: Two way Fixed network • Data-Reports Transmission to SWWC • SWWC commands to meter

Vendor Evaluation for Automatic RF Meters Evaluation Criteria to Rank 8 AMR Vendors: • Compatibility with existing water meters • Low flow accuracy • Strength of transmission signal • Encapsulated one-piece vandal deterrent module • Financial Stability of the Company • FCC License • Material & Workmanship Deficiency + AWWA Accuracy Warranty • Battery life expectancy • Hourly 6 month Consumption history • Data transmission in submerged conditions • Last 15 year performance in Texas • Meter register malfunction due to silt in water
AMR / AMI Project Objective:Find one vendor who can supply and install TX wide in 6 months, an accurate automatic water meter, and a reliable RF frequency network system, which provides the best return on Investment, for the lowest life-cycle cost
Evaluation Process Technology Research Preliminary Selection Vendor Technology Presentations Detailed Evaluation and Ranking Field visits to working systems/demos Meetings with clients Final Evaluation and Ranking RFP, Bid Review, Vendor Proposal Presentation, and Award
