Irish Water in partnership with Wicklow County Council, is carrying out the final phase of a programme of maintenance work on Wicklow’s reservoirs. The project is being carried out to inspect the condition of the reservoirs and to enable Irish Water to carry out any maintenance works that may be required. These works will improve the quality of the drinking water and increase the security of the supply for the people of Wicklow. 

The reservoirs included in this phase of the programme include the Hollywood and Donard, Valleymount/Ballyknockan and Barndarrig reservoirs. Work was completed last year on the Coolboy/Coolafany, Kiltegan, Knockananna, Knockanarrigan, Rathdangan, Stratford, and Thomastown Reservoirs.

The Hollywood and Donard Reservoir is the first reservoir to be included in this phase of the programme and work will take place from 12:00 noon on Tuesday, 16 May to 12:00 noon on Thursday, 18 July.  Irish Water will write to all affected customers prior to the work taking place ensuring they are kept fully informed of the programme.  Tankers will be located in Hollywood at near the Hollywood Inn and Tuttys Bar and in the Square in Donard village while the work is being carried out.

Work is planned to take place on the Valleymount/ Ballyknockan Reservoir from 12:00 noon on Tuesday, 30 May to 12:00 noon on Thursday, 1 June and on the Barndarrig Reservoir from 12:00 noon on Wednesday, 21 June to 12:00 noon on Friday, 23 June.  Irish Water will write to all households and businesses before the planned work is scheduled to take place.

To facilitate the maintenance work, the reservoirs will be emptied, which may cause an interruption to customers’ water supplies. The works at each reservoir will take two to three days to complete and alternative water supplies, through the provision of water tankers, will be provided to customers during the duration of the work. Once the reservoirs are drained an inspection will be carried out to determine if any upgrade work is required. This might require the reservoirs to be out of service for longer, but customers kept informed on all updates during the project. All the reservoirs will also be cleaned during the programme.

Commenting on the programme Ger Brady, Regional Engineer at Irish Water said “Irish Water is committed to providing a high quality and secure water supply for the people of Wicklow. It is important for us to inspect all our assets and carry out routine maintenance work. We apologise to customers who may be impacted by water interruptions during programme. I wish to reassure our customers that this programme is important part of Irish Waters ongoing improvement works on our water infrastructure in County Wicklow”.
