Manx Utilities is asking dog walkers not to leave dog mess around the Island's vital water supplies.
It says recent inspections around the Island's reservoirs have seen a rise in dog fouling, particularly at Clypse, Kerrowdhoo and Cringle Reservoirs.
The organisation says dog walkers should clean up after their pets using bags and bins provided.
It says uncollected dog waste can contaminate water catchment areas and it'll put up temporary notices and signs to remind people.
