Municipal lives for plumbing (D20)
24 municipalities in Ontario and British Columbia state a life for plumbing as a whole, in 17 distinct tables: 15–50 years, median 25. These come from capital asset policies: accounting lives, used for amortization. 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. The dashed line is the median. Policies that copy the same table count once.

Open questions
- HUD's 50 years for sewage ejectors may describe the basin and piping rather than the pump. Pump lives need a second source.
- Only one source so far: HUD planning lives for US multifamily housing. Canadian and observed sources are needed.
- Some maintenance intervals come from TM 5-692-1, an Army manual for mission-critical (C4ISR) facilities; they may be tighter than typical commercial practice.
