Storm sewer, catch basin and stormwater pond useful life
What 30 municipalities in Ontario state in 31 published asset management plans and capital asset policies, component by component, beside the library's sourced entry. Every life links to the page it comes from.
These are lives municipalities assume: amortization periods in capital asset policies (accounting lives) and replacement forecasts in asset management plans (planning lives). None is a measured age at replacement. Policies that copy one shared table count once.
| Component | Municipal median | Range | Tables | Library entry |
|---|---|---|---|---|
| Concrete storm sewer | 90 years | 50–100 | 6 | 90 years C |
| PVC storm sewer | 50 years | 50–110 | 3 | 110 years C |
| Storm manhole | 62.5 years | 50–80 | 10 | 62.5 years C |
| Catch basin | 50 years | 50–90 | 15 | 50 years C |
| Stormwater pond | 50 years | 25–100 | 13 | 50 years C |
Municipal median: the median of the distinct stated lives (a range counts at its midpoint). Tables: independent tables behind them. The library entry combines these with US federal sources; its page shows how.
