Wild birds and foul must be prevented from landing on exposed raw water pools at Drumshanbo Sewage works.
The call follows a motion from Leitrim Councillor Enda McGloin who has argued that netting must be installed over exposed water at the plant.
Following widespread support for the motion, Leitrim County Council have agreed to make the request of Irish Water.
Birds and foul such as seagulls and ducks can carry harmful germs that can sometimes spread to people and cause illness.
With recent weeks seeing outbreaks of Avian flu in Monaghan, Councillor McGloin believes measures must be taken to reduce any risk of transmission.
"Now it's very exposed in the sense that. when one drives by, you can see the exposed water and on occasions, birds, including ducks, seem to land on this particular plant. Many people have expressed their dismay and concern. Given what we've learned recently in media reports about the spread of things such as avian flu, may people are concerned that birds that land or swim on the water, could expose them to many other forms of diseases".
