Whether originating from a food service facility, car wash, business performing vehicle and equipment maintenance, or another source, any F.O.G. reaching the sanitary sewer system can cause a variety of problems. Issues range from sewer line clogs, possibly causing sewage overflows or backups, to decreased treatment efficiency, resulting from the microorganisms at the sewage treatment plant being metabolically overloaded with an overabundance of  grease.

Residential users

Be aware that keeping F.O.G. out of the drainage system helps both the Township and you. Many homes have drain clogs that can be attributed to the buildup of grease. 

When cleaning up after a meal   Dispose of food waste in the trash before washing dishes. The bottom line is the less fats, oil and grease that go down the drain, the better it is for everyone in the community! If you would like more information on what residents should or shouldn’t flush, please visit  Pretreatment and the Homeowner in Cranberry Township.

Commercial users 

Our program is designed to reduce the impact that F.O.G. has on the wastewater system. Commercial users are required to employ devices such as grease traps, grease interceptors, or oil/water separators to aid in F.O.G. removal. Maintenance is crucial to maintain proper function. Cleaning and service should be performed at least quarterly on the separators, unless stated otherwise, and is a Township requirement to avoid excess F.O.G. coming in to the sanitary lines. 

The F.O.G. program, from start to finish. 

Sizing Guidelines  All new and renovated facilities must complete and submit the sizing guideline worksheet. Note: These worksheets will open in Excel spreadsheets.

Installation  The pretreatment administrator must inspect the device after it has been plumbed but prior to backfill. The device must pass a vacuum test by holding 10 inches of mercury for one minute, as stated in Chapter 17.

  • Permit Application The application  gathers contact information, and information regarding the cleaning service that will maintain the trap.
  • Permits Issue a (example: wastewater permit ) to the facility with the potential to discharge F.O.G. in accordance with the pretreatment ordinance.  
  • Cleaning Logs  All commercial facilities are required to maintain a log of grease interceptor cleaning activities. This log sheet must be available to inspectors. F.O.G. Grease Interceptor Cleaning Log
  • Inspections - Inspections are performed at all permitted commercial facilities to ensure compliance.
  • Communications - Cranberry Township holds ongoing communications to help everyone remain compliant and keep our sanitary sewers F.O.G. free.
