Environmental Compliance

All traps (inside grease traps, outside grease interceptors, oil-water separators, and sand interceptors) must be designed in accordance with the Authority Sanitary Sewer Specifications and Standards. Plans and sizing calculations of the proposed traps must be submitted to the Authority for approval.

Any new or existing FOG generating business (food service, hair salon, pet grooming, car wash, automotive maintenance, etc.) is required to obtain grease trap approval. The grease trap approval process consists of two steps:

1. Design Approval Process – The following items are required to receive a Grease Trap Design Approval Letter:

  • Two complete sets of plans
  • Grease trap sizing calculations
  • Grease trap manufacturer’s specification sheet of the grease trap proposed for installation

Once the aforementioned items have been received by the Authority, a Grease Trap Design Approval Letter will be issued to the applicant. The Grease Trap Design Approval Letter must be submitted to the City of Peachtree City Building Department as part of the Building Permit process.

2. Installation Approval Process – Consists of two inspections:

  • Preliminary Installation Inspection – Inspection of visible plumbing lines within foundation for grease trap connection and inspection of grease trap installation (if required) prior to covering with dirt, sand, and/or concrete.
  • Final Installation Inspection – Inspection of kitchen wastewater piping connection to grease trap; complete inspection of grease trap installation (if required) including manhole lids, vertical tees, horizontal tees, cleanout caps, etc.

After the Grease Trap Installation Approval Process has been completed, a Grease Trap Certificate of Approval will be issued to the applicant.

Listed below are associated documentation used in the grease, oil, and sand interceptor plan review and approval process:

Grease, Oil, and Sand Interceptor Sizing Information


Grease Trap Sizing Information for Inside Grease Traps Only

The purpose of the Authority’s Fats, Oils, and Grease (FOG) Program is to assist in the prevention of sanitary sewer backups and overflows from occurring within the wastewater collection system through management of commercial and residential generated FOG. These FOG prevention process includes plan review, installation approval, and inspection of grease traps, grease interceptors, oil-water separators, and sand interceptors.

The FOG Program ensures that restaurants, schools, hair salons, pet grooming salons, car wash facilities, automotive repair facilities, oil change facilities, etc. are in compliance with the Authority Sewer Use Ordinance through proper grease trap/interceptor installations, accurate FOG inspections, and adhere to established cleaning frequency schedules. In addition, the FOG Program educates the local public and residential, commercial, and industrial customers about methods and practices for preventing FOG from entering into the wastewater collection system.

** Residential Cooking Grease Disposal Program (FOG) **

Disposing of FOG correctly is essential to ensure your home’s plumbing and the Authority’s sewer lines don’t get “all choked up.” Pouring cooking grease down the drain is not recommended because as grease cools, it hardens, leading to “chokes” in your plumbing or sewer line. Even though we live in a warm climate, many fats harden at room temperature.

The aim of the Authority’s Grease Disposal Program is to help our customers capture and dispose of their cooking grease in an environmentally safe and effective way. Please return the used oil to the container it came in (if possible) or pick up a grease container that you can use to store and dispose of household cooking grease. Return your filled container to 1127 Highway 74 S, and exchange it for an empty container, ready to repeat the process. It’s that simple!

FOG Program Education

The Authority invests in FOG education in an attempt to garner compliance among its residential and commercial customers to properly dispose of FOG.  By preventing improper disposal of FOG, customers can help the Authority protect its sewer system, not to mention the environment.  Industry studies show that more than half of all sewer system spills and overflows are caused by FOG.

Rather than dispose of fats, oils, and grease down the drain, residential customers should let grease cool, place it in a can, and dispose of that can in the trash.  Also, customers can help protect the sewer system and environment by wiping food from dishes into the trash, before washing in the sink or dishwasher. Below are education materials that provide an overview of information and tips for the proper disposal of fats, oils, and grease, in addition to other helpful consumer behaviors.
