  1. Asset Management Planning for Pipe Renewal Peter Kraft Treated Water Planning

  2. PROBLEM PIPE FOOTAGE YEARS

  3. PROBLEM HOW MUCH? WHERE? (Macro) (Micro) Ductile Iron Grey Cast Iron Spun Cast Iron Pit Cast Iron 2010 2015 2020 2025 2030 2035 Life Cycle & Statistical Modeling Risk Modeling

  4. PROBLEM: How Much? All Pipe Footage Pipe PIT CI SP CI CA Years DI PVC 150 100 Pipe Footage (mi) 50 Pipe Cohorts 1900 1950 2000 Years

  5. PROBLEM: How Much? PIT CI SP CI CA DI PVC 70 50 Pipe Footage (mi) Pipe Cohorts 25 2010 2025 2050 Years

  6. SOLUTION: How Much? Combined Life Expectancy Projection 3% % Distribution System 2% Percentage of Total System Planned 2020 1% Current 2011 2030 2040 2050 2010 2020 Years

  7. SOLUTION: Which Pipe? RISK= Likelihood of Failure (LOF) X Consequence of Failure (COF) High COF Highest Risk Low LOF High LOF Lowest Risk Low COF

  8. SOLUTION: Which Pipe? Likelihood of Failure RAIL INTERSECTION MATERIAL AGE JOINT TYPE PRESSURE BREAKS Consequence of Failure STREET MORATORIUM POPULATION DENSITY HIGHWAY FLOODING NUMBER OF TAPS PER PIPE SENSITIVE CUSTOMERS 2010 PAVING

  9. SOLUTION: Which Pipe? Distribution Replacement Model Risk Results MILES RISK LEVEL

  10. BENEFIT: Pipe Renewal Selection MAIN_107593 RISK = 1224 BREAKS = 2 INSTALL = 1950 MATERIAL = CI NUM TAPS = 25 CONFLICT = 2010 CITY PAVING

  11. BENEFIT: Identifying Vulnerability Sensitive Customer: Hospice PIPE AGE: 86 Years Old (1) BREAK: Jan 11th2001 PRESSURE: 80-100 psi LENGTH: 584 ft

  12. BENEFIT: Pro-active Planning & Coordination

  13. BENEFIT: Interdivisional Effort • PLANNING • Institutional Knowledge & Input • Long Term Renewal Planning • Life-Cycle Modeling • Risk Modeling • Annual R&R Candidate Selection • O&M • Field Knowledge & Input • Leak Detection • Condition Assessment • R&R Project Work • IT • EAMS Data Tracking & Integration • Ongoing upkeep of enterprise databases Asset Management Planning Process • FINANCE • Cost accounting for breaks as well as R&R projects • Financial Modeling for long term planning - i.e. bond rating, rate increase, revenue stability) • ENGINEERING • Institutional Knowledge & Input • Corrosion Section – ongoing assessment of leaks • ARG – maintenance of GIS distribution system • PUBLIC AFFAIRS • Institutional Knowledge & Input • Sensitive Customer Identification & Tracking • Input for risk modeling regarding social consequences • Communication w/ customers about aging system and rate increase
