THOUSANDS of residents have reported dirty water coming out of their taps across south London this morning.

The issues are affecting people around south London with complaints reported by residents in Croydon, Mitcham, Morden, Tooting, Wimbledon and Raynes Park. 

Social media website, Twitter picked up reports of water issues from as early as 8.30 am today (January 28).

Thames Water have confirmed their engineers are working on the issue in SW17. 

"The odourless discolouration was caused by maintenance work. To be clear it is not contaminated water," said Thames Water. 

Tooting MP Dr Rosena Allin-Khan tweeted a photo of a glass of her "dirty water."

Thames Water have apologised for any inconvenience caused by the water issue.

A spokesperson said: “We’re really sorry for the inconvenience and worry.

"We have a team of engineers in the SW17 area, who’ve identified the cause of the discoloured water this morning.

"They’re currently flushing this water from our pipe system, and we’re already seeing the water returning to normal.

“The odourless discolouration was caused by maintenance work, which disturbed some naturally occurring sediments within the pipes and although drinking the water would be harmless, we know it looks unpleasant and wouldn’t expect people to drink it until supplies are clear again.

"Many customers are already reporting clear water and we expect all supplies to be clear within the next few hours.

"To be clear the water is not contaminated or harmful to health and it’s certainly not sewage. The sewage and drinking water systems are completely separate."
