Info & Registration


The City of Lynchburg is in the process of developing a program to address fats, oils and grease from food establishments. These products will cling to the walls of sewers and eventually cause blockages and subsequent overflows. Any new food establishment being proposed will be required to install an exterior grease interceptor. Existing establishments being either enlarged or converted to food establishments should also install an exterior grease interceptor. For information on this developing program, you may contact an Industrial Monitoring Coordinator at 434-455-6240.

Preventing Sewer Backups at Your Business

If your business discharges fats, oils, or grease (FOG) you are required by the City of Lynchburg to pretreat the discharges containing these materials. Controlling grease discharges makes good business sense. A grease blockage can shut a business down for several days and cost thousands of dollars in lost profits and cleanup expenses. A little preventative maintenance will help ensure that you are in compliance with City Code and avoid this costly problem.

Recommended Maintenance Schedule

Grease Traps may require inspection and/or cleaning weekly depending on the amount of grease entering the drains. If the establishment is cleaning the interceptor too often, the owner should consider modifying employee procedures to reduce the amount of FOG entering the drain or install a larger interceptor.

Gravity Grease Interceptors (larger concrete tanks) may require inspection and cleaning quarterly.

Criteria for Inspecting Grease Interceptor

All food service establishments suspected of causing problems to the collection system may be inspected and subject to fines. City of Lynchburg uses the following criteria for grease trap inspections:

  • 25% Loading: Good
  • 25% to 50% Loading: Cleaning Required, Verbal Warning
  • Greater than 50% Loading: Poor. Immediate Cleaning Required, Violation

Proper Maintenance Procedure for an Interior Grease Interceptor

Proper Maintenance Procedure for an Interior Grease Interceptor less than 100 gallons:

  1. Open trap and skim floating material into a garbage bag (Note floating material depth). Bail out water to facilitate cleaning. This water can go back in the trap when cleaning is completed.
  2. Remove baffle(s) if possible and then remove the accumulated grease and solids out of the trap or interceptor and deposit them into the same garbage bag. Note depth of accumulated grease and solids.
  3. Scrape the sides, the lid, and the baffles inside the trap to remove as much attached grease as possible and deposit the grease into the same garbage bag
  4. If self-cleaning, contact a hauler/recycler to collect the grease or properly dispose of it into a dumpster.
  5. Replace the baffle(s) and fill the trap with water. Replace the lid.
  6. Record maintenance performed on the attached Maintenance Log, including the volume of grease if possible.

Proper Maintenance Procedure for an Exterior Grease Interceptor

  1. Keep an extra gasket on site for your grease trap/interceptor's lid to prevent leaks and odors in the event of a gasket failure.
  2. It is recommended that a professional service be used to ensure proper maintenance for Exterior Grease Interceptors.
  3. Facilities experiencing high employee turnover or other factors making regular trap/interceptor maintenance difficult should consider using a professional service.
  4. When contracting with a grease pumper service, it is in your best interest to find out how the contractor will dispose of the waste. Obtain references from other businesses that use their services. Witness all grease interceptor cleaning and maintenance to ensure you are getting value for the cost of cleaning the grease interceptor. To properly clean the interceptor the entire contents must be removed, which includes the scraping of the walls, floor, baffles and pipework. The return of gray water back into the interceptor is strictly prohibited.

Prevent Grease from Entering Storm Drains

  1. Cover outdoor grease storage containers so that they do not collect rainwater. Rainwater can carry grease and eventually reach the stormwater system.
  2. Locate grease storage containers away from storm drain catch basins.
  3. Use absorbent pads or other material to clean up spills in the dumpster area and dispose of through solid waste procedures.
  4. Do not clean equipment outdoors since water can flow to the gutter, storm drain or street.
