It is being claimed that Irish summer colleges are facing the threat of closure because of water charges.

Hundreds of teenagers spend up to three weeks in native-speaking areas of Donegal learning Irish during the summer.

Many of these students are housed and fed by local families in the area, with each keeping up to 12 students each per summer.

Now the families fear that when they house the students during the summer months, their water bill could become astronomical.

Niall McCafferty told Highland Radio this could be the final nail in the coffin for the Irish language.
