Southern Water and Thames Water have both released YouTube videos
highlighting what can cause sewer blockages at this time of year.
Southern Water said three quarters of all sewer blockages are caused by things that should not enter the system and fat causes some of the worst problems.
Simon Parker head of wastewater at Southern Water said: “We always notice an increase in fat in the sewers around this time of year as so many people are at home cooking Christmas dinners and more fat than normal ends up down the sink. However, our message applies all year round – sewers and treatment works are built to deal with human waste, toilet paper and water. Anything else should be put in the bin.”
