Thames Water has confirmed that the colouring is from iron sediment caused by disturbances to the pipework.
A spokesperson for Thames Water said: "The water is safe, though may smell or taste off."
Many residents have bought bottled water from the fear of using their off-coloured water.
Thames Water has said the water needs to be 'flushed out of the system' by keeping the taps off for a while - then opening the kitchen tap on full for a few minutes.
Some homeowners have called for further advice as their water continues to be off-coloured despite running the tap for minutes.
The water company said they are currently investigating.
No info as to when the issue will be resolved has been released.
