A grease trap or grease interceptor is a receptacle which is located between the drain lines and the sanitary sewer lines.
It’s function is to allow for the separation and collection of fats, oils and greases (FOG) from the used water and preventing these materials from entering into the municipal sewer system. There are a variety of businesses that use grease traps including: restaurants, pubs and bars, supermarkets, grocers, coffee shops, and cafeterias.
A grease trap can either be located in or outside the facility. Typically with larger restaurants or other kitchen facilities the grease trap/grease interceptor is located outside of the facility, usually in the ground, whilst facilities with smaller grease traps are usually housed indoors. At United Sewer Service we are experts in the pumping and cleaning of exterior and interior grease traps.
Why do I have to have a grease trap?
FOG can create significant problems for municipal wastewater systems, for this reason governments require commercial facilities to have a grease trap installed. Most municipalities will have a minimum amount of FOG that is acceptable in the water leaving an establishment. If you exceed these minimums, fines can be imposed.
