Fats, oils and grease (FOG) (PDF) can be discharged to the sewer system, so long as the concentration remain within acceptable limits as defined by Chesterfield County’s Sewer Use Ordinance and Local Limits. Excessive discharge of FOG can accumulate in sewer pipes and manholes, commonly referred to as the collection system. This accumulation, over time, could result in blockages within the collection system which, in turn, could cause overflows into surrounding waterways or sewer back-ups into homes or businesses. This would be hazardous to public health and safety and aquatic life.
The FOG best management practices (PDF) minimize the discharge of FOG to the sewer system in accordance with Chesterfield County’s Sewer Use Ordinance Chapter 18 Article IV Section 18 to 103.
Grease Interceptors (GI)
Any business that discharge fats, oils and grease (FOG), must install a grease interceptor (GI) inside or outside of the building. GIs must be properly maintained and are subject to inspection by Chesterfield County’s inspector. The inspector ensures that the equipment is functioning as designed and that it is being cleaned and serviced properly.
