PROBLEMS with the water supply at Exeter's West Exe school may finally be sorted.
But youngsters are continuing to drink bottled water at St Peter's for the time being.
Last week the Echo revealed that contractor Carillion had spent around £1m trying to solve the problems with the water supply at Exeter's secondary schools, which were built six years ago.
One member of staff at Carillion was found to have falsified a reading taken from the supply at St Peter's, and has since left the company.
And papers released by Devon County Council revealed the battles the local authority has had with Carillion to try and resolve the problems.
But as the new school year begins, West Exe can finally return to mains water supply.
Headteacher Vicki Carah said Carillion had carried out some pipe replacement, local hardware changes and disinfecting over the summer holidays.
She said: "It is business as usual at the moment and we are monitoring the situation, we have no reason to think it will recur. Staff and students have been fantastically patient and understanding through a very difficult time, parents too.
"That we got record results despite the inconvenience is huge testament to all concerned."
In a letter to parents she said: "We are assured that the water supply no longer requires additional or temporary measures and we are in a 'business as usual' situation.
"The last sets of readings have shown no concerns re legionella and all the drinking fountains have been replaced so the readings for metals are also as they should be. Carillion have worked hard to rectify the situation over the summer holiday and will be finished just in time for the new term.
"Devon County Council and school representatives will continue to meet with Carillion and MSEL to ensure that the situation remains as positive as it is at present and we will, of course, let you know if there are any further concerns."
A spokesman for the county council said that although they are working, the showers remained temporarily out of use at the school as a precautionary measure.
Most of the city's secondary schools now have new drinking fountains which provide chilled water.
But there is still a problem at St Peter's.
A council spokesman said: "Students and staff at St Peter's will continue to use bottled water in the short term.
"Only one drinking water outlet has returned a reading marginally above the expected standard and the school says it wants to be able to tell parents the entire system has been declared 'all clear' before returning fully to the regular water supply."
