ENGINEERS are having to spend millions of pounds cleaning fat from Yorkshire’s water and sewer pipes.
More people than ever are disposing of cooking fats, oils and grease by pouring them down the sink.
This has led to a greater number of blockages in the sewer networks, says Yorkshire Water.
Last year Yorkshire Water removed nearly 14,000 sewer blockages in Yorkshire. Some one in three of these came after deposits of cooking fat, oil and grease built up in our sewers.
Forecasts for all of 2008 indicate that the number of blockages caused by such substances is likely to increase, potentially topping 6,000.
Cooking fat, oils and grease get into sewers from household drains, usually via the kitchen sink and appliances such as dishwashers.
Over time these substances build up on the inside of the sewer pipe, reducing the flow capacity and leading to blockages.
Brian Smith, of Yorkshire Water, said: “Fats, oils and grease aren’t just bad for your arteries, they’re bad for your drains and the sewers serving the community.
“They can cause blockages in sewers, which can lead to people’s homes being flooded and watercourses polluted.
“Our message is very simple. We’re asking people to put their sewer on a low fat diet and think before they dispose of fat, oil and grease down the sink or through the dishwasher.”
