Residents in parts of Penrith are without water this morning.
United Utilities says it is investigating the issue, affecting the CA4, CA10 and CA11 postcodes.
A statement said: "We've found a leak near to Salkeld Road and confirmed this to be the cause for some of you having no water or just a trickle.
"Our leakage engineers have been requested to attend and will be on site as soon as possible.
"We’re sorry for the inconvenience and hope to have your taps flowing again very soon."
It was reported just before 8am today.
