As of a July 19, 2006 amendment to Ordinance #387, the use of manhole style grease interceptors has been disallowed in new restaurants. A large vault style interceptor is the minimum District standard.
Anyone involved in the remodeling or construction of a restaurant of any size should contact Mark Eddington, P.E., District Manager at the DeKalb Sanitary District for an appointment to discuss grease trap specifications. Call 815 758-3513 between the hours of 8 a.m. and 4 p.m.
DeKalb Sanitary District collections system personnel often receive customer or neighbor reports of grease spills or are called out to check sewer mains that are backed up only to discover the sewer lines are blocked by grease from nearby restaurants.
Costs and Fines
The facility responsible for such blockages is liable for the costs to clean and clear the sewer line and possibly for any costs for damage done to adjoining properties, as well as for fines up to $1000.00 per day for violation of local ordinances.
Denial of Service
Regulations may also require the installation of a larger, more efficient grease trap. It is even possible that the offender might be disconnected from sewer service to halt or prevent a discharge that presents an imminent endangerment to the health or welfare of the population.
Rules for Grease Disposal
***The use of additives (chemical or biological) or hot water to emulsify grease and allow it to pass through a grease trap circumvents the purpose of the trap and is therefore not acceptable.
DeKalb Sanitary District staff make unscheduled random visits to food service license holders to:
While existing restaurants and food service establishments are allowed to use interior or the smaller type of exterior grease trap that was legal at the time of their construction as long as they do not contribute grease to the sanitary sewer lines, it is recommended that they “upgrade” to the current specifications. Problems with grease clogging sewer lines in their vicinity or discovery, upon inspection, of improperly maintained grease traps will result in a mandate to install the required type.
If you have any questions regarding these very important issues, please call the DeKalb Sanitary District at 815 758-3513.
