Delegates to the annual World Toilet Summit in Northern Ireland's capital deliberate on crucial issues like anti-social activities in rest rooms, portable toilets, and amenities for the blind.

Raymond Martin, director of the Irish Toilet Association, says delegates have launched a "Bog Standard Campaign" to advocate better toilets in UK schools. They have also inaugurated Belfast's first public UriLift toilet, a stainless steel urinal that rises hydraulically out of the ground to facilitate male users.

During the conference, Singapore was chosen as a model for the rest of the world as far as public toilet excellence.
