BOTTLED water is being provided to students at all of Exeter's PFI schools while water quality tests continue.
Devon County Council has described the move as a precautionary measure after Legionella bacteria were detected at West Exe Technology College, and high levels of metals were found in the water supply at St Peter's C of E High School.
Legionella – which can cause illnesses including the potentially fatal Legionnaires' disease – has not been found at any other Exeter school.
Efforts to eradicate the bacteria at West Exe are continuing after a deep clean during the Easter holidays.
And while work goes on to resolve the long-running issue affecting tap water at St Peter's, bottled water is also being provided to staff and students at St James School, Isca College of Media Arts, St Luke's Science and Sports College and Wynstream Primary School.
All the schools were built or rebuilt by Carillion under a £79m private finance initiative contract between 2004 and 2006. Carillion is paying for the bottled water supplies.
