Shambolic Thames Water has admitted roadworks in St Dunstan's Road will now not finish until 'next week at the earliest' after a second problem was discovered at the site.
The initial work, to fix a sewage pipe, was due to have been completed today (Wednesday), but had already looked set to overrun until at least Friday after bungling workmen jammed a camera below ground, which had been probing to find faults in the pipe.
They were forced to dig up the road to fish it out but no sooner had they done that and re-concreted the surface that another cracked pipe was found, which will mean further delays and more misery for drivers and bus users in Fulham Palace Road.
Hammersmith and Fulham Council claims the latest mishap was the result of another bungle, saying the collpase was caused due to the weight of another camera and its caged casing, although Thames Water denies this, insisting the second crack formed independently.
The council labelled the latest delay a 'scandal'. Councillor Greg Smith said: "It is scandalous that Thames Water monopolises this busy road - which is next to a hospital - for a whole fortnight, lurching from one blunder to the next, while motorists are stuck in huge traffic jams.
"Fulham Palace Road and the surrounding areas have been gridlocked and now the misery will continue for yet another week. Thames Water need to buck up their ideas and do a proper survey so that this doesn't happen again."
A spokeswoman for Thames Water said: "Engineers had completed the job on the initial sewer blockage in St Dunstan's Road yesterday but when they were finishing off the work, a collapse 15 metres further down the pipe was discovered.
"Emergency work is being done to repair this and we hope to be finished by early next week. This is a must-do job which we have to get on with immediately and we are sorry for any inconvenience caused."
The blunders are the latest in a long line of misdemeanours by Thames Water. The firm was forced to overrun on roadworks in Fulham Palace Road last month after the council deemed its initial efforts unsatisfactory.
And the same road suffered more disruption in November when a leaking pipe was left unattended and subsequently froze over, causing several accidents.
The company is also under fire for its plans to build a construction entry point for the controversial Thames Tunnel, known as the 'super sewer', in Carnwath Road, Fulham.
