Grease is the Word

Grease is the Word

After our extreme Summer weather, most of us won’t be surprised to experience the ‘other side of the coin’. We’re preparing ourselves for more extreme weather and this may well be vastly increased levels of rainfall. Combine this with the Fats, oils, grease and food waste we have disposed of down kitchen sinks, toilets or drains, then we can start to prepare for more flooding and pollution.

What happens to the environment?
Our sewers were designed to carry sewage and not other forms of waste. Where these sewers also carry rainwater from our roofs and other paved areas, any accumulation of debris in the drainage system can rapidly overload the network. Where storm overflows exist in our sewers this can lead to unnecessary discharges of untreated sewage into our streams and rivers. Where such overflows do not exist, sewage flooding can occur to homes, businesses, parks, gardens and other open spaces.

What happens to the fat?
Fats, oils and grease (FOG) in liquid form may not appear to be harmful but when disposed of into the drainage system they mix with food and other sanitary waste, congeal and harden in the pipe. Over time this builds into blockages.Using detergents or bleach may have some impact on clearing grease and other debris from the pipework beneath the kitchen sink, but these chemicals have little impact when they become naturally diluted in the sewer network.

We don’t like Food Macerators
The use of food waste macerators only makes things worse in our sewers by grinding up waste food, including any fats, and releasing it into the drainage network.

What happens to the waste pipes?
Gradually the fats, oils and grease build up in the sewer network until blockages occur. This is a significant problem.

What’s the answer?
Prevention is better and far cheaper than the cure. Call us and we’ll arrange for one of our team to take a look and see if you’re storing any problems up for winter. If you are, we provide a fully Dosing Service, that gives you piece of mind and can prevent you from getting a hefty repair bill!

Fat Facts

  • Blockages account for 80% of sewer flooding incidents in the UK and more than 5,000 properties are flooded each year as a result.
  • There are approximately 370,000 sewer blockages throughout the UK every year, of which up to 80% are caused by fats, oils and grease, wipes, sanitary waste and other unflushable items.
  • Around £100 million is spent annually on reactive blockage clearance nationwide, with further costs for clean-up after flooding incidents. These costs will be paid for through customer bills.
  • Through sewer flooding, FOG build-up is indirectly responsible for many cases of property damage and pollution incidents.
  • Even when FOG compounds cause few problems in sewers, they can result in serious difficulties at sewage pumping stations, including problems with build-up.
  • If we all take care not to dispose of fats, oils, grease or other food waste into the sewerage system, the number of customers affected by flooding and the impact on our environment will be significantly reduced.
