Scottish Water has received planning permission from Fife Council to raise the height of the stacks at Levenmouth Waste Water Treatment Works as part of on-going work to minimise odours from the site.
This project will result in the current 15 metre high stacks being replaced with two 30 metre stacks
The move has been welcomed by both Lindsay Roy MP and David Torrance MSP.
Mr Roy congratulated Scottish Water on the investment and said it was clear they were now taking the odour problem in Methil seriously.
Mr Torrance said he was pleased a hopefully permanent solution to the smell had been found.
Anne-Marie Dewar, regional community manager, said: “A number of significant operational improvements have already taken place, for example chemical dosing to counteract odour sources in the sewerage system.
“Replacing and raising the height of the stacks represents a major investment in the plant and will result in increased dispersion of the treated odours. Construction work is likely to start in early 2015.”
