People in Torry have been warned a pong plaguing the area is likely to get worse before it gets better.
An expert hired by Scottish Water to advise on the ongoing problem has revealed the treatment works at Nigg will need major investment to bring it back to full health.
Professor Rob Jackson has already given his assessment of the situation to members of Torry Community Council.
There were 75 complaints lodged about the odour last month – and 82% of these were traced back to the Nigg plant.
Prof Jackson said: “The wastewater treatment works at Nigg is now perhaps best described as overworked and tired.
“It needs a great deal of money to be spent on it to return it to 100% performance.
“This problem will not be solved this summer.
“Odour problems in the community may in fact get worse before they get better.”
The Scottish Environment Protection Agency (Sepa) has now appointed a full time Torry odour response officer, who will respond to complaints from the community.
Local community council secretary, David Fryer, said: “I welcome the appointment of an odour inspector who will work full time.
“The community council encourages everybody who encounters the odour to get in touch and get a reference number from the odour response officer.
“What we say is don’t moan – phone.
“Together with Professor Jackson we have to ensure that the odours get resolved once and for all.”
Later this month stakeholders – including Scottish Water, the community council and Aberdeen City Council – will be given access the Nigg site.
A spokesman for Scottish Water said: “All key stakeholders, including Professor Jackson, will be visiting Nigg Waste Water Treatment Works on July 16 for a tour of the works and process.
“All operating assets, be they of a water or waste treatment nature, are subject to wear and tear over a period of time, requiring a maintenance service programme.
“The work Professor Jackson refers to forms part and parcel of that mid-life maintenance.”
