He said on Thursday, 8,000 customers in Whitstable were without supply as storage reservoirs serving the area had “reached a critical level”.
“We expect customers will start to see tap water supplies return later today, but this may be intermittent over the weekend,” he added.
Benton said 7,000 customers were currently experiencing low pressure or an intermittent supply in Tankerton, Ashford and its surrounding areas, Ulcombe, Cranbrook, Coxheath and Headcorn.
He added a further 7,000 customers were “at risk” of experiencing some supply loss on Thursday.
“We are sorry to customers who have had interruptions or low pressure in their water supply and know how frustrating it is, especially in very hot weather,” he said.
