Storms which battered the area last Thursday resulted in tonnes of sewage being pumped into the river – and this picture of a heron in the middle of it has convinced one Hammersmith resident of the super sewer's merits.

Whenever there is torrential rain, the area's old sewers get overpowered, forcing the release of effluent into the river to stop it running into the streets.

It is one of the main arguments for building the super sewer, and Hammersmith embankment resident Ann Styles agrees after snapping the bird struggling near Hammersmith Bridge.

"I'm not a environmentalist but looking at the poor heron surround by this muck convinced me the tunnel is a no-brainer," said businesswoman Ann.

"This is long overdue in my opinion because it cannot be justified for the river to be polluted on this scale."

Ann insists her stance wouldn't be different if she lived in Carnwath Road, and points out her home is very close to another mooted tunnel shaft site at Hammersmith Embankment.

"There are going to be a load of developments going on in this borough over the years to come anyway. There will always be disruption of some kind.

"But this construction will be of benefit to the whole of London in the long run and is definitely worth it."
