Joanne Laeger, EA’s environment planning and engagement manager, said people needed to “be prepared” for the continued dry and warm weather, including holidaymakers.
“Water companies are responsible for managing public water supply and that’s from supplying water as well as trying to manage the demand for water,” she said.
“They will be trying to reach out to holidaymakers and visitors to try to make sure that people use water as wisely as possible when they’re visiting our lovely area.”
Cath Jones, CCW’s head of engagement, said it was “absolutely vital” holidaymakers did not overuse water supplies.
She said: “This is not a one-person or just a residents issue, it is so important that people visiting the area understand.
“We want them to take shorter showers, not a bath, we do not want to see people refilling at hot tubs every weekend because there’s new people coming to a property.
“We cannot have people watering lawns just to make them look green for a tourist – that is absolutely things that we must stop.”
