It followed a series of complaints from local residents which were raised with the Environmental Protection Agency by Sinn Fein T.D. John Brady.
Deputy Brady says the problem has been ongoing for a number of years, which on some occasions, forced residents to leave their homes.

One of those actions was to upgrade the odour control system which Deputy Brady says Irish Water has confirmed has now been completed.
