The site had been temporarily closed after the discovery of traces of legionella bacteria.

Police Scotland Headquarters, Tulliallan, is set to reopen from Monday.

It follows the closure of the site on December 6 after traces of Legionella bacteria were found.

Legionella bacteria can cause Leggionaire’s disease - a form of pneumonia. It’s most commonly found in natural water sources but can also be found in purpose built water systems. 

Remedial work has now been completed on water systems and although some buildings and rooms will remain isolated for testing and further work, the force has said officers and staff can safely return to the site.

There were no confirmed cases, and the force has said the risk to people was always extremely low.

DCC Fiona Taylor said: “Our water safety experts have confirmed officers and staff can safely return to Tulliallan and training courses can resume.

“Measures including routine water sampling, temperature control, increased flushing and robust disinfecting will continue across the site and some rooms remain isolated for the time being.

“As at all times, the safety of officers and staff, and those attending our buildings is a key priority.”
