Slip-lining is far less expensive than digging up the streets to repair and replace old utilities (for situations it is even applicable).

Probably time to reconsider the compounds we use in lots of things, now that we know more about them though.

In the US it is, in other countries, not so much. My city was devastated by earthquakes in 2010-11 and we are still repairing damaged drains. For us it is generally cheaper to dig up and lay new drains. Part of the problem is that the existing drains have lost their fall so relining them is fairly pointless.
