Work is under way to tackle the smell from a sewage plant close to Glasgow's main Commonwealth Games venues.
The £500,000 programme will see tanks cleaned and valves refurbished at Dalmarnock Waste Water Treatment Works.
Scottish Water said residents and businesses in the vicinity may have to persevere through a temporary increase in odour while work is carried out.
Celtic Park and the under-construction Sir Chris Hoy Velodrome and National Indoor Sports Arena are all nearby.
The first phase of work at the plant will see four storm tanks cleaned and the refurbishing of isolation valves which allow the storm tanks to be closed.
Gary Caig, Scottish Water's team leader for waste water in the area, said: "Scottish Water recognises that odour issues at Dalmarnock - which serves about 260,0000 people across the east end of Glasgow and in the north east of the city - are important for residents and businesses in the vicinity and for the development of the area.
"We also recognise that the Dalmarnock area will play a key role in the Commonwealth Games and Scottish Water is committed to doing all it can to help ensure that the Games are successful for Glasgow and Scotland."
