Sanitary sewer useful life by material
What 20 municipalities in Ontario state in 20 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.

| Concrete sanitary sewer | 100 years | 60–125 | 8 | 80 years C |
| Clay sanitary sewer | 65 years | 50–100 | 5 | 80 years C |
