Well Sparky there's no point in ranting and raving and getting under the skin of the poor chaps fixing the problem, they're doing their best.
Anyway - 20:30 Sunday Evening, and I've been able to wash my Wellies off under the outside tap - yes WE HAVE WATER

The front garden now looks like The Somme with slit trenches, piles of earth, cut down hedging, but at least given time it's all repairable. The restitution team are apparently going to turn up on Monday or Tuesday, fill in the trenches, level the piles of earth, and re-turf the lawn.
I'll take some pictures when the sun returns
