MEETING OF LUCAN / PALMERSTOWN / NORTH CLONDALKIN AREA COMMITTEE

Tuesday, May 23, 2023

QUESTION NO. 16

QUESTION: Councillor A. Hayes

To ask the Manager to provide a detailed report on the accumulation of liquid on the hill behind "Palmerston Lodge" house that borders Mill Lane park and Stewarts Old Building in Palmerstown as previously logged by Cllr Alan Hayes under Members Rep 1780625. Dublin City Council did investigate following initial contact by a concerned resident and found the following: 1. Very silty/cloudy water was apparent flowing down this 900/750 SW Sewer from the direction of the Applegreen Garage at end of Chapelizod By-Pass. This was discharging via a stream into the River Liffey. There appears to be a CSO near the garage but it does not look like sewage in the discharge. 2. This SW sewer could not be found. Our crew did not find evidence of sewage at the location identified by the Customer. 3. 450 dia Lucan Sewer appears to be operating normally - no evidence found of surcharging or overflow to the Liffey. Could samples be taken to determine the contents of the overflow and provide a report on the cause and any potential negative impacts.

REPLY:

A pollution incident was investigated by the Council's Water Pollution Section at this location.  The Water Pollution section report that: 

The cause of the problem was determined to be a blockage of a private sewer line, which was cleared and pollution ceased shortly after the time of the initial report.  A re-inspection of the area on Wednesday 17th May showed the area was now restored to its normal natural condition.
