Drains fully repaired with new wonder lining from Germany. Bravoliner bends to fit the pipe, then is heated up and sets hard. It's guaranteed for 50 years. A bit expensive, but a lot cheaper than digging up the road.
We have a new hi-tech version and it is the first drain in the UK to use it.
A lot of digging is going on nevertheless. EDF had to dig up the drive and replace a T-junction from the 1930s, tropical fish saved and street lights back on. Only managed it by this afternoon though so power was off all night. Trenches still being hollowed out for gas and water.
