FOG Alert – Protect the sewer system against fatberg buildup!
Many Canadians aren’t giving this issue a second thought. A lot of people are carelessly disposing of fats, oils and grease (FOG) by pouring it down kitchen sinks and toilets. People may think it’s not a big deal if they do it once, twice or three times; but because of this, fatbergs are forming in local wastewater systems and costing taxpayers a lot of money in clean-ups and repairs.
With damage to sewer infrastructure on the rise, taking action and making clear changes for a better environment is essential. Releases of fats, oils and grease into waterways pose a very large threat to public health and safety.
The food industry along with residential and industrial sewer users are major sources of FOG discharge. However, only food service establishments (FSEs) and industrial sewer users require to take action in reducing the amount of FOG discharged into the system. While FSEs require to have a grease intercepting system in place, excessive amounts of FOG may still be entering the sewer system due to:
- Grease interceptors reaching their end of life
- Microbial and chemical corrosion, causing grease interceptors to deteriorate and malfunction, which in turn releases grease into the wastewater
- Improper or infrequent maintenance of the grease interceptor.
What are fatbergs?
FOG released into sewer systems can come into contact with improperly disposed of items, such as wet wipes, diapers and bandages – all things that should not be flushed down toilets or drains. FOG in the sewer will bind to these improperly disposed of items, creating a mass that will accumulate more debris and FOG. Eventually, the mass will become too large for wastewater to continue flowing through the sewer line. The solid mass, also known as fatberg, will eventually choke off the flow of wastewater. The result is a Sanitary Sewer Overflow (SSO) in which raw sewage may be forced through manhole covers and basement drains, and into streets, houses and businesses.
Fatbergs are large blobs that:
- Grow and multiply
- Generate foul odours
- Block sewers
- Damage sewer pipes and may even cause cracking
- Results in sending raw sewage spilling into the streets
Did you know in 2017, workers in London, England discovered a fatberg measuring over 800 ft. long and weighing approximately 130 metric tons; this is the size of 11 double-decker buses! If this doesn’t get you wanting new grease interceptors, nothing will.
Not only are fatbergs dangerous and gross, it’s also costing taxpayers a large amount to treat.
This is a lot of money going to something that can easily be reduced or fixed with proper maintenance and knowledge of grease interceptors.
Effects on the environment
This is an ongoing issue that has a huge impact on environmental costs and ecosystems like the death of aquatic and terrestrial animals. It’s time to re-think grease interception! We believe interception is the best defence. That is why we work with cities, municipalities and regulatory agencies to develop long-term solutions.
