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.
