11. Case Study: 2015 Winston Salem Wastewater Master plan

12. Winston-Salem/Forsyth County Utilities Commission – System Overview
Over 90,000 Sewer Customers
1,724 miles of Sewers
49 Lift Stations
36 MGD treated daily
3 primary sewer basins
CASE STUDY: Winston-Salem

13. Winston-Salem MP – Asset Management Elements
Organization Assessments:
PAS 55
CMOM
Facility Assessments:
Condition & Criticality Scoring
Asset Group Life Cycle Analysis
Pipeline Assessments
Desktop analysis
By sub-basin

14. PAS55 – Checklist for Good Asset Management Practice
Similar to ISO Standards and Guidance

15. PAS 55 Asset Management Maturity Scoring

16. Pas55 Gap Analysis Results
Strengths:
Contingency Planning; Communication, Participation, and Consultation; Legal; Tools, Facilities, and Equipment; Compliance Evaluation
Improvement Focus Areas:
Asset Management System; Risk Management; Life Cycle Activities

17. CMOM Evaluation High Priority Recommendations:
Capacity Management: prevent SSOs through proactive cleaning and focused preventative maintenance.
SSO response: Record rainfall data to track wet weather SSOs
Customer Service: Track information on the status of SSO serve requests
Low Priority Recommendations:
Capital Planning: Do a better job of coordinating project planning between the C&M and Capital planning departments
C&M: Develop a post-SSO water quality management plan
FOG program: Identify major contributors and budget for education
On-track with previous (2012) recommendations resulting in a drop in SSOs/100 miles from 16 in to just 7 in

18. Facility assessments Lift Station Inspections Hydraulic Capacity
Condition and Criticality
Risk-Based Prioritization
Life Cycle/O&M Improvements

19. Lift Station Inspections
Condition and Criticality Ratings by Asset Group:
I&C
Electrical
Structural
Mechanical
Pumps
Pipes
Valves
Auxiliary Equipment: Generator

20. Risk-based prioritization
Developed from Inspection Condition and Criticality Ratings

21. Pipeline assessments Condition Scoring Criteria
Criticality Scoring Criteria (Consequence of Failure)

22. Pipeline Prioritization by Sub-basin

23. Winston-Salem Asset management Recommendations & cip budget planning

24. Ramping up on Asset Management activities

25. CIP Budget planning – Collection System Rehabilitation and Replacement (R&R)
“firm 75-Year” pipeline service Life
In the second graph the high magnitude of spending from is spreadout over the entire next decade. Useful life of 75 years (only)
“Condition managed”
Pipeline service Life

26. CIP Budget planning – Collection System capacity and R&R

27. MANAGING THE CIP AND BUDGET FORECASTS USING iCIP
Add, remove, or update projects via an interface with GIS
Update project phasing based on system performance triggers
Update and refine projects stemming from on-going R&R program
Provides dynamic CIP budget forecasting and reporting
Immediately shows results of decisions
A customized technical approach for project success
