In late November 2025, a major supply failure at the Pembury water treatment works left tens of thousands of customers of South East Water (SEW) without running water. The plant was shut down on the evening of 29 November after the company admitted that a "bad" or "chemical" batch of coagulant chemicals had contaminated the treatment process. South East Water apologised and reported that approximately 24,000 homes across Tunbridge Wells, Pembury, Frant and Eridge experienced a loss of water supply or reduced water pressure at the peak of the outage.
