Chantry Library will remain closed for longer than expected as test results show that more work is needed to make its water safe.

The library in Hawthorn Drive closed to customers on May 8, after bacteria was found in the water supply in parts of the site.

A routine test showed the presence of legionella, which can cause a pneumonia-type illness known as Legionnaires’ disease, and a mild flu-like illness called Pontiac fever.

Chantry Library was swiftly closed, and a spokesperson said that “immediate steps” were taken to prevent anyone from accessing the affected water supply.

It was anticipated that the library would reopen on Tuesday, after the Bank Holiday weekend.

However, it was confirmed on Thursday that this would not be possible.

A spokesperson said: “While water treatment and testing continues, we are unable to reopen Chantry Library on 28 May as planned.

“Unfortunately, although we hoped and anticipated after treating the water the results would be clear, they show further treatment is required so the process has to be carried out again.

“The library is likely to be closed for a further two weeks but we will keep customers informed when we know more.”

However, the spokesperson said they also had some happier news to share.

“A positive outcome is that after discussions with the county council, we have been able to rearrange some planned building work to replace the library roof,” they said.  “This can now take place during the closure and will prevent further disruption later this year.”

The spokesperson reminded users that they can continue to access other libraries, with the nearest one being Stoke Library based at Stoke High School, as well as the libraries in Broomhill, Gainsborough, Rosehill and Ipswich town centre.
