Restaurants are being urged not to pour their leftover fat and grease down the sink this Christmas, in order to avoid unwanted drain blockages.
The Consumer Council for Water has warned that washing oil away with soap and hot water will only cause blockages in the plumbing once the fat starts to cool. Blockages in pipes and drains can cause wastewater to back up, leaving restaurateurs with more than a kitchen-full of sewerage to deal with.
Tony Smith, chief executive of the CCW, said: “The cost of having your own drains unblocked can be expensive, and if the public sewers are blocked, the sewerage companies` costs in removing blockages get passed on to customers via sewerage bills.”
Fat, oil and grease should be poured into an empty container, wiped into the bin with a kitchen towel, or poured into a ‘fat trap’, which are provided by most sewerage companies and are free to collect.
While fats, oils and grease being poured down the drain cause three-quarters of blockages in the UK, over the Christmas period this figure rises by an estimated 25 per cent.
