Severn Trent apologises over Worcestershire water problems
Severn Trent has apologised after pressure problems affected water supplies to around 20,000 homes in Worcestershire.
Homes and businesses in Bewdley, Stourport and Kidderminster were affected with many customers losing their service completely.
A spokesperson said they had restored the service just after 11:00 BST.
Engineers discovered faulty valves at the Mount Pleasant reservoir during planned maintenance work on Monday.
General manager of operations, Steve Witter, said: "I'm sorry if you have had low or high water pressure or if your water supply was interrupted and for any problems this may have caused you."
He added that customers may experience temporary discoloration of their water supply once it is restored but this posed no health risks.
