Digital Innovation and Data Integration Key to Successfully Managing Charlotte’s Sewer Rehab Program Aaron Frazier - Frazier Engineering Keith Shirley - Charlotte Water Chris Allen – Charlotte Water

Charlotte Water’s Service Area Population >800,000 4,200 miles of sewer Mint Hill Matthews Pineville Huntersville Cornelius Davidson Charlotte Mecklenburg Co.

Yearly Rehab Budget and Program  Yearly Rehab Budget of $13 million  Rehab Construction  Root Control  Clean and TV Contracts  Engineering

Find-and-Fix Annual Contracts  Primary Rehab Construction Method - $7 - $8 million per year in construction  Fast Tracks Projects from Design to Construction  Saves Substantial Time and Money – estimated savings of over $8 million since 2000

Massive Amounts of Data Drive the Find-and-Fix Annual Contracts. Data Integration and Using Digital Technology are key to success and quick decisions.

Data Inputs into Rehab Decisions SSES Work  Smoke Testing  Manhole Inspections CCTV Data  >500,000 LF/Year  6 different sources Acoustic Inspection  SL-RAT  2 different sources Flow Monitoring Data  Temp and Perm  Smart Covers GIS Data

Data Inputs into Rehab Decisions Historical Records  Sewer Backups  Customer Complaints  Backflow Preventers Hot-Spot Areas  Root Control  Routine O&M  Grease Control  Critical Assets

Data Inputs into Rehab Decisions Rehab Work  Past Work  Current Work  Planned Work  Cost of Work Work by Others:  CIP Projects  Stormwater Projects  Pavement Resurfacing Projects

All of these inputs are reviewed continuously for every rehab area/project issued. The rehab projects move very quickly. We spend $600,000 or more every month on rehab construction. The work is all over Charlotte’s extensive service area. Need quick and efficient decisions.

Data Management Procedures  “Old” Procedures: GIS Mapping and Information GIS Mapping and Information Spreadsheets to track rehab work Spreadsheets to track rehab work Spreadsheets to track other data inputs Spreadsheets to track other data inputs Digital Database/Software for CCTV Digital Database/Software for CCTV InfoNet Software for SSES Data InfoNet Software for SSES Data  All Data Collected and Stored Digitally

Data Management Desires  Combine all data into a single location: Look at all data at the same time Look at all data at the same time Quicker and more efficient access to data Quicker and more efficient access to data Better/easier reporting and tracking Better/easier reporting and tracking Better access to data by Charlotte Water Better access to data by Charlotte Water Cost and time savings Cost and time savings

Required Data Outputs General Reporting  Maps……and more maps  Data……and more data  Report requests….and more requests  Work performed by Basin or Area  Decision makers  Community groups

Required Data Outputs (cont’d) SSES Reporting  Past SSES Results  Current SSES Areas and Results  Planned SSES Work  Historical Flow Data Rehab Reporting  Past Rehab  As-Built Data  Current Rehab  Planned Rehab  Estimated Costs

Required Data Outputs (cont’d)  Issue work directly to SSES Crews and Rehab Contractors – streamlined process…...  Quickly and Efficiently Coordinate all Data Inputs with Proposed Rehab Construction Work

Improved Data Management Procedures  “New” Procedures: Upgrade to InfoMaster Software Upgrade to InfoMaster Software GIS integrated with InfoMaster GIS integrated with InfoMaster Move away from stand-alone spreadsheets Move away from stand-alone spreadsheets  All Data Collected and Stored Digitally

Results  We upgraded from a “basic” data management “system” to a single, robust data management software program  Data integration and database development have been costly and time consuming…but beneficial…  Don’t expect this to be “easy”  Don’t expect this to be “inexpensive”  The costs are on-going and will continue…….  Make sure you are prepared to “tackle” this – time and budgets…  “New” costs are offset by current data costs

Benefits  Data Queries – Improving  Data Queries – Improving ↑  Data Outputs – Improving  Data Outputs – Improving ↑  Data Reporting and Analyses – Improving  Data Reporting and Analyses – Improving ↑  Rehab Tracking – Improving  Rehab Tracking – Improving ↑  Rehab Budgeting – Improving  Rehab Budgeting – Improving ↑

Benefits (cont’d)  Coordination of all available data when planning and designing rehab work – Improving  All work within Charlotte is better coordinated leading to a very successful rehab program

Considerations  Is our Data Management Plan the right decision for Charlotte??  Is your current Data Management Plan the right decision for you??  Is comprehensive data management necessary for your system??  Is the budget available to implement such a system??  Are you collecting data digitally??
