A BURST water main at the Trevu Reservoir has left up to 18,000 properties and two schools in the Camborne and St Ives area with no water or low water pressure, says South West Water

It said: "The burst was quickly isolated in the early hours of this morning, but a re-valving exercise is currently under way, which may take some time to complete and for a pressurised supply to reach the required level.

"Alternative water supplies are being provided to the most vulnerable customers with registered priority needs.

"We apologise for the inconvenience caused as we work to restore supplies as quickly as possible."

Cornwall Council says St Meriadoc Infant Academy and St Erth schools have had to close until further notice as they currently have no water. Camborne Nursery School is also closed due to water leak.
