4 Some figures (a real-world example) Average pipe age? (R: 20 years) Most used materials? (R: High density polyethylene; 10% older pipes: asbestos cement) Average capital maintenance budget? (R: 500 k / 2,3% present accounting value ) Utility estimate for the average useful life for those materials? (R: 50 years) LNEC /57

5 For the previous replies The network true value is aprox. 60 % of the replacement value (i.e., still young; mature infrastructures should be aprox. 50 %). For the current rehabilitation rate to lead to sustainable networks, pipes would need to last on average 173 years instead of 50! If the current rate is kept constant, in 47 years the utility would provide NO SERVICE. LNEC /57

6 Activity costs What is the (sustainable) relationship between capital maintenance costs and operating costs in a mature water infrastructure? According to studies of the National Research Council (Canada): Aprox. 50% - 50% for public services supported in civil works infrastructures LNEC /57

7 Long term impact of the rehab. rate IVI = present value / replacement value Time (years) k k 500 k LNEC /57

17 What is IAM? My favourite definition... (Infrastructure) «asset management is the art of balancing performance, cost and risk in the long term. (Brown; Humphrey, 2005) LNEC /57

18 Not trivial!... I shall adopt infrastructure life cycle analysis, right? I was told this is the leading edge! R: Not literally! These infrastructures do not have a limited time live!

19 Infrastructures have indefinite lives We receive infrastructures from others We use them and manage their value We pass them on to the next generation Urban infrastructure 2015 Time window 2050 LNEC /57

20 Where to be in 2050? How to manage transition? 2050 (ref. TRUST, LNEC /57

28 Infrastructures have indefinite lives Key for our success! Key for societies survival! We receive infrastructur es from others We use them and manage their value We pass them on to the next generation Urban infrastructure 2013 Time window 2050 LNEC /57

29 Infrastructures have indefinite lives Adequate service Increased efficiency IVI aprox. 0,50 We receive infrastructur es from others We use them and manage their value We pass them on to the next generation Urban infrastructure 2013 Time window 2050 LNEC /57

30 Key requirements for a successful implementation Strategic views are adopted Users needs and expectations are duly managed Clear processes and good data Alignment and feedback between decision levels are ensured (strategic/ tactical/ operational) Alignment between management processes are ensured LNEC /57

35 Frequent shortcomings Water services taken for granted in modern societies low political impact of capital maintenance efforts low willingness to pay and willingness to invest in rehabilitation lack of capital maintenance LNEC /57

36 Frequent shortcomings Emerging challenges and long-term objectives e.g., adaptation to climate change, efficient use of energy, use of new paradigms for the water systems often do not have an impact on operational management of the assets Capital maintenance actions tend to use a like-forlike replacement approach often ignore long-term objectives and strategies Lack of effective alignment between strategic tactical operational level LNEC /57

37 Alignment through decisional levels Strategic Management alignment Tactical management people involvement empowerment feedback Operational management LNEC /57

38 Frequent shortcomings Often, strategic planning is not long-term e.g. implementation of BSC (Balance Score Card) on a yearly perspective. e.g. KPI adopted LNEC /57

39 Example: economic efficiency Less than 5 years: Promotes cuts in capital maintenance > 15: Sustainable capital maintenance becomes crucial LNEC /57

40 Frequent shortcomings Data are the foundation of IAM, but in general: too little data (NOT ENOUGH) or too little GOOD data (NOT RELIABLE) or too many (fragmented) data and information sources (NOT EASY TO USE) LNEC /57

41 Frequent shortcomings Prevalent IAM - emphasis placed on: Asset condition Risks of failure (LOS not applicable to individual linear elements) Priority on what asset(s), when, where Not enough thought given to what alternative solution LNEC /57

42 Frequent shortcomings The existing context differs from design assumptions e.g., Energy Sustainable use of materials DMAs implementation changes the hydraulics Fire-fighting design paradigm versus water quality Capital maintenance interventions are opportunities for systems improvement!
