It's bad for business."

Mr Rucastle said that despite their postcode being a short distance away from the main area affected, he remained concerned as "it's all on the same pipeline".With temperatures expected to remain at about the 20-22C (68-72F) mark in the next few days, Susan Brash, from Ingleton Parish Council said local residents were understandably concerned.

"I think about people who have animals that need water. Is it going to affect them?"Southern Water monitors all its storm overflows. The company records when and for how long a discharge is happening.

Permits are issued to water companies by the Environment Agency, which decides under what conditions storm overflows can be used.The agency said they should not spill on dry days, but there are exceptions.

An Environment Agency spokesperson said: "Storm overflows, like Ham Lane, must only be used under strict permitted conditions that control their environmental impact."We will always seek to hold those responsible for environmental harm to account.
