UPDATE: Thames Water says sewer service at Wembley Triangle restored and traffic should be back to normal by the end of today.

 

I was told to expect a statement from Thames Water about the situation at Wembley Triangle yesterday but none was forthcoming by midday today so I tweeted them at midday.  The incident began on Thursday. LINK

Their answer is above. 

UPDATE - Neil Levy of Thames Water has sent the following message:

We managed to work all night yesterday to repair the sewer and we have demobilised from the site now.

 
We found that the sewer was severely blocked with rubble, bricks and fat, which we believe may have caused a break in the pipe.

 
We have restored the sewer service and there has been no further flooding or pollution impact to the environment.

 
We apologise for any inconvenience this has caused but traffic should be back to normal by the end of today.

UPDATED: Thames Water report Wembley Triangle sewage leak. Potential pollution of Wembley Brook.

 

WEMBLEY TRIANGLE TONIGHT

 A resident reported: No engineer in sight but  no leak either. From Wembley Hill Road the road is closed to the left if you wished to go down Harrow Road. From Harrow Road coming into Wembley there is no right turn into Wembley Hill Road.

By all accounts is chaos, as from Wembley Hill Road you have no choice but to turn right into the High Road.  Vehicles are going across this junction and turning in St Josephs RC Church car park then leaping out to turn right on to Harrow Road towards NCRd.  A few are attempting to turn left at the triangle and  dicing with death as it doesn't appear that the traffic lights are giving them the option.

 Thames Water has reported to Brent Council that a 'big crack' opened up overnight on the road at Wembley Triangle. Sewage escaped from the main sewer about 3 metres below ground and cascaded into roadside gullies.

Thames have classified this as pollution as it leads into the Wembley Brook (of recent fame).  At the time of informing Brent Council. Thames said there had been no real impact on the brook at present but further work would be done today to investigate further and survey the pipe. This will establish the reapirs need to return the sewer to normal service and prevent any further flooding or pollution.

Wembley Matters has asked the Thames Water officer responsible for an update on the situation after today's investigation.
