Wastewater from commercial kitchens is contaminated with FOGS (fats, oils and greases). Introduction of FOGs and food solids into the general drainage/sewage system (either main sewage network or private treatment facilities) is detrimental to its proper function and has been shown to be a significant cause of blockages, restrictions and flooding.


The FOGI Grease interceptor/separator range has been designed to conform to both Building Regulations Part H and also BSEN 1825 the British Standard for Grease Separators/Interceptors. The FOGI’s design will effectively intercept (FOGS) fats, oils and greases and solids before they enter a wastewater drainage system in so supporting the effectiveness of both the drainage system and the final treatment process. FOGI interceptors/separators are designed for larger kitchens and restaurants as well as use in industrial food processing applications and meet all the requirements of the relevant legislation


For smaller kitchens and catering establishments we have an extensive range of both underground and above ground grease treatment systems available. Please ask for more details
