How does this help the op and it seems to be inaccurate.

Pvc under a driveway not encased in concrete must be 24" down while your chart shows 18". That may be true for one and two family dwelling but it doesn't say that or I am just blind

The posted charts are for commercial, residential and industrial applications not public works, like streets, highways.
