The Town of Leesburg prohibits the discharge of fats, oils, and grease (FOG) down the drain in amounts that will cause or contribute to a blockage in the sewer collection system. Sanitary sewers are designed to carry the normal waste discharges from a residence or business. When FOG byproducts are discharged into the sewer, it can accumulate on the interior of the sewer pipes. Over time, this accumulation of FOG restricts and/or blocks the flow of wastewater which can result in sanitary sewer overflows, sanitary sewer "back ups" in residential and commercial properties and other discharges into the environment.

To ensure compliance with town standards, the Environmental Compliance Inspector inspects food service establishments and non residential facilities annually.

FOG is a byproduct of many foods.  Among the most common are; bacon grease, butter, margarine, lard, gravy, shortening, dairy products, fat scraps from meat, mayonnaise, cooking oil, fryer oil, fryer grease, salad dressing , milkshake mix and ice cream. All commercial facilities are required to implement Best Management Practices (BMP's)

How does this affect you?

  • Sanitary sewer blockages and overflows can disrupt your business which can cost you money. Fines can be incurred if you are found to be contributing to blockages in the sanitary sewer.
  • Raw sewage is a health hazard.
  • Sewage overflows into our waterways are illegal, and can subject the Town to fines for each one that occurs, and will further increase the cost of our sewer service.

The cost of grease blockages and sewer overflows are ultimately paid by you.

What is required of my business to prevent FOG discharge?

  • Use Best Management Practices (BMP's)
  • Intercept the FOG and remove it from the discharge with a grease interceptor. 
  • Know where all FOG devices are located and how to open them.
  • Inspect and maintain the interceptor routinely.
  • Train all employees and post signs and instructions where they are needed.
  • Record all inspection, cleaning, maintenance, and training activities.
  • Keep all records for at least 3 years.
  • Communicate.
  • Take pride in doing your part.

See the Plumbing and Drainage Institute PDI Standard G101-2017- Testing and Rating Procedure for Grease Interceptors, Section 8 for guidance on grease interceptor sizing.  A guideline to assist in evaluating interceptor sizing can be found here

FOG Inspections

Town staff will conduct annual FOG inspections. The Environmental Compliance Inspector will make efforts not to perform these inspections during peak business hours. At a minimum during the inspection, the inspector will request the cleaning schedule and/or manifests. The inspector may also physically inspect FOG devices to ensure compliance.
