I suppose I'm thinking of this too simplistically.
Send someone to check and mark hole/leak
Dig a hole
Repair pipe
Fill in hole.
They need a team of people just to answer the phones and deal with the website enquiries plus all the updating on the leakage incident map that's difficult to find and almost tells you nothing of any use apart from something is happening at that spot.
They then send a team of specialists to locate said reported incident, checking for possible further damage, flooding and the like. Approach other utilities to see who else might have vested interests in said hole. That team is probably about as useless as the water companies. Sort out planning permission and then set up a week of traffic lights on a 4 way system for maximum hinderance even though the leak is on a footpath on a quiet cul de sac
Spend another week mulling if they should just repair the bit of pipe with the leak or the whole section, them victorians didn't make things last.
Once the repair is done wait a week so it can be inspected by all interested parties.
Fill in the hole but don't make it the same as the surroundings, can't have a proper job. Then wait for the nearest homeowner to moan that the hole has sunk and his car is stuck in the drive.
Involve the team of people answering the phones ...............
