Shannon-Erne Waterway users have been advised that the pump-out at Belturbet is temporarily out-of-order.
In a statement to Northern Sound, Waterways Ireland says this is due to the construction of Cavan County Council's new service block, which will bring an increase in facilities for waterway users in Belturbet.
It's expected the electrical connection will be re-established in early June, in line with the builder's latest programme of works.
A Marine Notice will be issued when the pump-out is operational.
In the intervening period, Waterways Ireland advises that alternative boat pump-out facilities are available at Aghalane, Galloon and Knockninny.
