The Junior Tourism Minister Michael Ring will be invited to open the Water world facility in Bundoran this year.
A works programme including new facilities and improved insulation measures have been introduced which will help to reduce the running costs of the service.
Waterworld will reopen to the public this Easter bank holiday weekend.
Fianna Fail Councillor Sean McEniff proposed that Minister Michael Ring is invited to carry out the official opening. He says it will help to gather publicity for the event.
