A sewage works situated upstream on the River Forth in Scotland was used to coping with high volumes of water. The failure of one of the brush rotors created a major problem. With DO and ammonia levels likely to go haywire in the warm weather, a solution had to be found quickly.

Instruction was given by a Scottish Water Team Leader to use Corgin for temporary aeration. Three days later, four spiral aerators were operating in the ditch and the site was saved

Scottish Water commented: "As soon as we put your kit in, the DO started rising immediately. It made a real difference."

The spiral aerators remained on hire for five months until the rotor was finally repaired.

One of Scottish Water's process scientists said: “Corgin are on speed dial and we will be in touch if we have a hot spell like last year!”

18 months later, and approaching the Christmas holidays, another brush rotor went down at the treatment works, and Scottish Water again turned to Corgin. Despite the time of year, the spiral aerators were despatched the same day, and were installed and running the very next day.
