Severn Trent Water have apologised after sending out a letter informing residents of a road closure a week too late.

Dursley residents were furious when a letter warning them of the closure of Silver Street arrived on Tuesday, when the road had been closed the week before.

Severn Trent Water closed the road to clean and re-line the sewer.

Residents complained of 'traffic chaos' last Monday, with many drivers not aware of the closure and cars being diverted down narrow streets with cars parked on either side.

They vented their frustration on social media upon receiving the letter.

One commenter on the Dursley Matters Facebook page called the letters 'a waste of money and resources' while another quipped that they 'probably got stuck in the traffic jams'.

A spokesperson for Severn Trent Water said: “We’re extremely sorry to customers who live on Silver Street, for the late arrival of a letter informing them about planned work we were carrying out on their road last week.

"An admin error caused the delay, which we understand has caused a great deal of frustration for residents.

"We’re reviewing our processes to prevent this from happen again.”

Seven Trent's £1.5 million work to upgrade Dursley's sewer network started back in April and is expected to finish at the end of summer.

More than 4km of waste pipes are being relined and refurbished.
