The National Aquatic Centre (NAC) (Irish: Sportlann Uisce Éireann) is a water-sports facility located in Abbotstown, Blanchardstown, Ireland.
The NAC was built to be the home of Irish swimming, with modern facilities such as its 50m competition pool (one of only three in Ireland), diving pool with movable floor, and leisure centre — it is Europe's largest indoor water leisure facility. The centre was completed and opened in March 2003 and hosted the Special Olympics in August 2003 and the European SC Championships in December 2003 .
In January 2005, the centre sustained roof damage during a period of stormy weather and it had to be closed for five months in order to receive repairs. This closure, after only 18 months since opening, was seen as damaging the business of the operating company, Dublin Waterworld. Campus & Stadium Ireland Development, the State company which owns the centre, commissioned an engineer to assess the roof damage and they stated that the roof was not designed and constructed in accordance with the building regulations. During the closure period CSID commenced legal proceedings to remove the operators. The centre re-opened to the public on 20 May, 2005.
The centre is now home to many swimming competitions including the Irish Long Course Championships and Leinster Age Groups. Many clubs around the Dublin area use the competition pool to train in, although training hours in the pool are limited.
The diving pool is also used for water-polo matches and tournaments. It can also be difficult to get training hours in the diving pool due to competing commercial demands.
