Irish Water says it’s going to call into households where people have been reportedly breaching the hosepipe ban during the heatwave
The utility is continuing to monitor supplies, as it considers extending the ban beyond the Greater Dublin area.
The measure looks set to continue for several months.
43 water supplies have introduced night-time water restrictions including parts of Dublin, Portlaoise, Athlone, and Galway City.
Over 100 areas are at risk due to high consumption including places like Clonakilty and Bantry in Cork.
