Residents have complained of an “unholy” smell as they claimed sewage was running down their street.

Photos have emerged online of a brown liquid trickling for tens of metres down New Park Drive, Hemel Hempstead, this morning following the heavy rain last week and over the weekend.

One resident suggested it was due to ongoing works by Affinity Water in the adjoining Leverstock Green Road, adding: "We have a stream of sewage water running down New Park Drive now, the smell is unholy!”

A spokesperson for Affinity Water said: "We experienced a burst main on Leverstock Green Road yesterday, affecting clean water supply but not sewerage. I can now confirm that the issue has now been fully repaired."

The road has been closed since September 24 and is due to be lifted today (September 30) according to One Network, although workers were still pictured at the scene this morning.

Affinity and Thames Water have been contacted for more information.
