On 16th September, and not for the first time, the A41 was badly flooded northbound at Brent Cross. When will you sort out the drainage of this road, so that traffic is  able to flow properly at times of heavy rain?

TfL has a pumping station at this location which worked as planned throughout the recent heavy rainfall.  They have however contacted Thames Water relating to limited capacity of the drainage system beyond the pumps and Thames Water acknowledges capacity constraints on their network.  These could potentially be addressed by Thames Water constructing an attenuation tank, the cost of which has been estimated to be in the region of £7m and is being considered in conjunction with potential works related to the Brent Cross Redevelopment.
