1 Real Time Savings: Transforming Real Time Hydraulic Data into Actionable Information Luis Montestruque, Ph.D. President EmNet, LLC Patrick Henthorn, P.E. Assistant City Engineer City of South Bend

2 Agenda The Problem Defining Goals and Objectives Real Time Monitoring System From Data to Information Real Time Decision Support System Results

3 3 Case Study: City of South Bend, IN

4 4 City of South Bend, IN Population: 107,000 WWTP: 77 MGD 500 miles of sewer lines Combined Sewer System 20 square miles 36 CSO discharge points Separate Sewer System 20 square miles LTCP Tunnel, separation, WWTP expansion LTCP Cost: $450M East Race Environmental Sensitive Area

5 South Bend Goals and Objectives Eliminate dry weather overflows Prevent basement backups Better understand system hydraulic performance Maximize flows to WWTP and explore RTC Calibrate model 5

6 6 Data Originators Options Area Velocity Flow Meters Different vendors/ different applications More detailed data (flow, level, velocity) More expensive Level Transducers Standard (ultrasonics, sonar, pressure) Data: level (calculations needed) Inexpensive TRADEOFF

7 CSS SCADA Points: 17 RT-DSSPoints: 110 SCADA System: Rockwell – RSView SCADA Monitored locations: 17 (mostly lift stations) Additional Monitoring: Based on Objectives CSO outfalls: 36 sites Interceptor: 27 sites Trunk lines: 42 sites Retention basins: 5 sites Cost: $3M Dense Monitoring System

8 8 Design to Fit Objectives: Easy deployment Battery operated Data every 5 minutes Low maintenance Development: University of Notre Dame Purdue University Results: Mixed 900Mhz/Cellular Deployed mid winter 2008 Deployment time 1 month

9 Immediate Objectives Focus on CSOs & Interceptor First priority – organize data and learn how the system behaves during wet and dry weather Un-learn what is normal Second priority – revise maintenance schedules Initial stage - Increase number of inspections Add calibration checks Focus on CSO service area cleaning Second stage – Reduce cleaning frequency Revise staff duties 9

10 10 Deviations from Model Weir ElevationWater Level Trunk line Throttle line Overflow line

11 11 Deviations from Model This is normal!

12 Small blockage forms CSO is vactored 12 Deviations from Model Weir Elevation Average Dry Weather Flow

13 Increased O&M Benefits Use of vactor trucks 50 additional days annually = $133K Clean 2000 additional catchbasins annually = $40K Increase number of sewer inspections at non-routine locations by 175% = $29K All this with Same Staff Total Dynamic Maintenance Value = $202, Its like hiring more personnel, but without the cost. Gary Gilot, Director of Public Works, City of South Bend, IN

14 Real Time Data Monitoring Sites 30,000 Data Points Per Day

15 Real Time Decision Support Systems 15 Data Information

16 SCADA Integration

17 17

18 18 Using GIS

19 Dry Weather Overflow Elimination 97% DWO reduction from 2008 to = $797,500 fines 2009 = $275,000 in 2009 fines 2010 = $27,500

20 Operations Optimization 20

21 Optimization In South Bend, IN Reduce CSO volume by balancing flows to WWTP Increase inline storage opportunities Increase storage ability in retention basins by up to 150% $120 Million Optimize CIP saving $120 Million Annual Overflow Volume Existing System (MG) Annual Overflow Volume CSOnet System (MG) Percentage Reduction (%) %

22 Summary Advances in information processing lead to new ways of performing maintenance, operations, and design Integration of real time data, model, and visualization tools provides new insight Future systems will further enhance capabilities by providing forecasting of hydraulic conditions before they happen
