Municipal lives for plumbing (D20)
26 municipalities in Ontario and British Columbia state a life for plumbing as a whole, in 18 distinct tables: 15–50 years, median 25. 34 rows come from capital asset policies (accounting lives, used for amortization) and 1 from asset management plans (planning lives, used to forecast replacement). They describe the system rather than this component, and none is a measured life.
Years. Each dot is one stated life and each bar a stated range; equal values stack. Hollow marks are planning lives from asset management plans; filled marks are accounting lives from policies. The dashed line is the median. Policies that copy the same table count once.
