Does not contain any drinking water abstractions (there are approx 1,200 more abstractions by Irish Water, and another unknown amount by Group Water Schemes)
Unclear if it contains the 25 plastic water bottling plants in Ireland, eg Ballygowan.
Redacts the names of the abstracting entities
Obscures the abstraction locations, so in an industrial complex you cannot tell which entity is abstracting
This is a Register not a Licensing system, so may be incomplete
Limited to just the really large abstractions (over 25,000 litres per day) so cumulative impact of smaller multiple abstractions are not included
With all these limitations, it remains useful as a starting point for anyone seeking to understand water abstraction in Ireland
