North East Water has warned the hot weather has caused a 'taste and odour' in some drinking water, but confirmed the water is still safe to consume.
In a statement on Facebook, the company assured residents the water was safe to drink.
"Customers may be experiencing taste and odour in their drinking water," it said.
"This is due to naturally occurring compounds in the raw water which can be more prominent in hot conditions.
