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

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

How Denton Uses Cit ityworks 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!

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

Coll llection System by In Install Year
- The use of
- The idea of
subdivision plat dates came with staff involvement
SLIDE 18
Basin in Cle leaning Pri rioritization
- The idea of 1, 5 and
10 year cleaning cycles developed with input from staff
SLIDE 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
