3 Presentation Scope Why asset management Software tools used in Denton asset management plan Discussion of asset management plan Empowering employees with front row seats in AMP development Benefits derived Infrastructure Renewal Planning Hydraulic Modeling Asset Framework & Information Solutions Operations & Maintenance New Capacity Delivery

4 Population Population Gravity Main Linear Feet of Gravity Sewer Main Denton s Collection System Has Expanded to Match Population Growth 160,000 3,000, ,000 2,500, , ,000 2,000,000 80,000 1,500,000 First sewer lines were constructed around the Courthouse in the early 1900s 60,000 40,000 20,000 1,000, ,

5 Why Asset Management Substantial investment in wastewater collection system assets ($0.5 Billion) Limited dollars for O&M and replacement Good steward of the environment, SSO reduction Work smarter High employee morale Lower rates, happy ratepayers

6 Software Tools Used in AM ESRI GIS Pipeworks/Cityworks CMMS Hydroworks/Infoworks Capacity Models WERF SCRAPS Prioritization Model CapPlan/Infomaster Asset Management Model Operations staff buy in Addition of IT/Database professional CMOM Program

7 How Denton Uses Cityworks CMMS Work orders for: Flushing program CCTV Point repairs Service line replacements Main line replacements Customer calls Odor complaints Chokes and overflows Manhole inspections EVERY ACTIVITY IN THE COLLECTIONS DEPARTMENT IS ENTERED AS A WORK ORDER!

8 Cityworks Combined with GIS for Flushing Program Example, Flushing Staff Vs IT

9 Cityworks Quality Control, WO Overload Created Need for Automation **SYSTEM GENERATED INSTRUCTION** Tested for batch closure Could not be closed because of the following: - WO CONTAINS INSTRUCTIONS **END OF INSTRUCTION**

10 Info Works Model to Plan Capacity

11 5 Year Capital Improvement Plan

12 Success of Wet Weather Program

13 SCRAPS Model Using Probability and Consequence of Failure SCRAPS provides a numerical ranking from 0 to 100 for each pipe segment, highest being worst Began focusing inspection and preventative maintenance in areas with higher risk based on the SCRAPS output Feedback from the field allowed for data corrections which brought down the average risk in the collection system

14 Benefits of Digital Database of Collection System That Accrued from Implementation of SCRAPS Model

16 O&M Staff continue to collect pipe data when flushing, Quick Cam, MH Inspections

17 Collection System by Install Year The use of The idea of subdivision plat dates came with staff involvement

18 Basin Cleaning Prioritization The idea of 1, 5 and 10 year cleaning cycles developed with input from staff

19 Enter CapPlan Sewer SCRAPS Model provided valuable priority ranking It is not a complete asset management system The next step was then to move to full asset management system
