How to Jumpstart a CMOM Program (Using Technology!)

Transcription

1 How to Jumpstart a CMOM Program (Using Technology!) T-Con 2015, Grayslake, IL Presentation Outline Background on NMWRD Past Collection System O&M Practices In-house CCTV Program Bad! Pilot Test CCTV with RedZone Good! Intervening Event: Sewer Collapse & SSO Full System CCTV with RedZone Project Scope and Experience Project Results ICOM-3 Data Management System GIS Export to Google Earth & ArcGIS Next Steps Conclusion and Recommendations 1

2 Began Operations in 1978 Modern Collection System, mostly truss & PVC pipe Serves Lakemoor, Island Lake and Port Barrington 2.0 DAF/5.0 DMF Oxidation Ditch WWTP Current Flow 1.0 MGD Collection System > 70 miles 22 Lift Stations spread over 35 mi 2 5,000 customers, 15,000 PE Staff of Admin, 3 Operators, 1 Supervisor, 1 Manager and ½ Lab Annual Operating Budget $2M 2

4 Believed that sewers are self-cleaning Sewer jetting/cleaning equipment used reactively Aries televising equipment purchased 2009 Operators received two days of training System sat hidden at lift station until spring of 2011 Purchased and outfitted televising trailer Launched CCTV program w/goal to TV 10% of system/yr. 4

5 Televised nearly 7 miles of sewer TV team mistook goals for objectives Televised recently installed/televised lines in order to reach mileage goal Due to lack of training, no coding of defects Defects recorded with digital camera pictures of laptop screen Unsure of line segments televised, camera direction etc. Several defects were discovered in one area as noted on the next slide 5

7 We know we have a problem We know where the problem is We know we need to fix it We kind of know some details We found similar defects in the area All appear to be installation related All appear to have remained the same for years Biggest, most critical problem??? 7

8 when full system CCTV is completed maybe! Contacted RedZone to CCTV high traffic area Did one week pilot test Selected worst areas along with traffic area RedZone Completed 6 miles in one week! District received data packet, with video PACP coded, graphic depiction of problems in test area 8

9 Expedited current state characterization of entire collection system in 12 months! NASSCO PACP & MACP coding of defects ICOM3 Asset Management Software and Hosted Data GIS Location of assets (X/Y of All Manholes) Four annual payments Immediate Board Approval! 9

10 CCTV of all 8-10 via Robots CCTV inspection of larger diameter piping via traditional camera PACP Coding Completed later in a warm office Incorporated & coded District s CCTV work Inspected all 1,505 manholes Daily progress report s & problem alerts ICOM allows quick analysis of problem areas Asset Management/CMMS, Work Order etc. 10

17 Completed CMOM Process Evaluated and Scheduled O&M based on actual condition for sewer cleaning etc. Assess and prioritize system repair needs based on criticality: potential for failure and consequence of failure Completed Comprehensive Capital Improvement Plan (CIP) Identified all urgent system needs, utility wide, not just what we can see 17

18 Completed a gap analysis of revenues vs. needs Created a sewer rate model that achieves goal of maintaining a sustainable utility Assured full cost of service rates achieved over time Fully justified needs based on an actual, full system assessment Exported data to Google Earth KML file for field use (work in progress) 18

19 Identify & re-evaluation needs of minor defects Schedule and execute point repairs Update Sewer Atlas with GIS data adding RedZone X&Y data to existing rim and invert elevations OR Invest in ArcGIS and export RedZone data to system Repeat 19

20 Total Project cost $359,530 Televised 302,832 Feet of Sewers +/- 60 Miles Plus 1,508 Manholes = $1.18/foot for pipe including Manholes in about 6 months time. Cleaned >80% system in prep for CCTV Work Space for RedZone Equipment, Internet connection for daily data upload Notice to Village Officials in service area Assisted in locating lost or buried manholes Responded to daily reports of blockages Received ICOM Training Only received two resident calls during program Added 8TB local network storage for CCTV files Have processed three annual payments 20

21 RedZone YES Program has been a great benefit to NMWRD Contains all components of a CMOM program Minimal Staff Involvement Condition Assessment Completed in 1 Year, not 10% of system per year for 10 Years! Powerful Data Management/Asset Management and Work Management software Cost was justified based on retiring staff Immediate attention to most critical needs Internal Condition of force mains External Condition of ferrous pipe 21
