Fatberg - The Hidden Menace

  • August 27, 2020




The accumulation of Fats, Oils and Grease (FOG) in a drainage system creates problems for commercial kitchens, food processing facilities and downstream infrastructure. FOG is generated from cooking processes and enters the drainage system via sinks, dishwashers and drainage outlets. 


Kessel size all their Grease Separators to the European Norm EN1825. 


The Building Regulations 2000 part H - Drainage & Waste Disposal (2002 edition) clearly set out rules for the management of grease :

2.21 Drainage serving kitchens in commercial hot food premises should be fitted with a grease separator complying with BS EN 1825-1:2004 and designed in accordance with BS EN 1825-2:2002 or other effective means of grease removal.

Grease Traps and Interceptors must be fitted by law to the following establishments:

Restaurants - Hotels and guest houses - Pubs, bars and cafes - Commercial kitchens

Fast food restaurants and takeaways – Bakeries - Food processing - Hospitals and healthcare facilities - Manufacturing operations - Industrial process applications

Untreated FOG has damaging effects on sewer infrastructure and wastewater treatment plants and downstream may cause surcharges and environmental watercourse pollution.
