The company said a UK survey showed that 25% more grease ends up in the sewers during the festive holiday season - and is having a disastrous effect.
As it cools and solidifies the grease can form blockages which have become known as 'fatbergs' - or at this time of year, 'turkeybergs'.
NI Water said it has dealt with around 20,779 sewer blockages in 2013 at a cost of £1.7m.
Des Nevin from the company is advising people to let fat oil and grease cool and solidify before scraping it away into the bin, rather than emptying it into the sink.
He said: "While the meal may be planned with meticulous detail, little attention is paid to what we put down the sink. When fat, oil and grease solidifies in the sewers it prevents wastewater flowing through the pipe, and often causes a blockage.
"When a drain becomes blocked and overflows, the consequences can be devastating. We can all play a part in maintaining the sewerage infrastructure from restaurants, pubs and hotels right through to home owners and industrial outlets."
