“We are very sorry for the impact this incident had on our customers three years ago.

"We take our responsibility to supply safe drinking water very seriously. We have invested more than £150 million on new technology and processes including a fail-safe system at Sweetloves treatment works, to make sure this type of event does not happen again, and customers can have complete confidence in their tap water.”
