QUESTION NO. 4

QUESTION: Councillor Yvonne Collins

To ask the Manager what long term plans are in place to resolve the problems with the water supply to the pond in Rathfarnham Castle Park

REPLY:

Some work was carried out in 2020 to identify the source of the problem with flow to the Rathfarnham Castle Pond and the situation regarding flow to the lake was improved as a result.  It should be noted that much of the length of this watercourse is located in private lands and this has presented difficulties for both maintenance and inspection of it.  A number of further items of work are planned, as listed below, however these cannot be carried out at the present time and will have to be deferred until after the lifting of the current Covid 19 restrictions. 

• The inlet to the pipeline is considered to be potentially problematic and may require alteration to address this issue.
• A loss of flow sensor will be fitted in the inflow pipeline to send an alert when flow levels have dropped.   These alerts can be responded to when received.
• A camera survey along the length of the pipeline is required to assess the condition of the pipe. This will involve the removal of tree roots or any other intrusions or debris in the pipeline.   
• After the extent of the weaknesses in the pipeline have been identified the appropriate manner to remediate the pipeline can be chosen.
