We Have an App for Fat

Walker Environmental Group is helping the City of London save money and improve their management of their grease trap interceptor programs with our Grease Interceptor (GI) Compliance software.

Grease traps are found in the plumbing of commercial kitchens. Grease traps remove fats, oils and grease (FOG) from wastewater before it enters the municipal sewer system. FOG is the leading cause of sewer damage and sewer system overflows. The proper installation, cleaning and pump-out of grease traps is an essential part of a healthy sewer system. To ensure that happens, municipalities have bylaws that set standards for interceptor installation and management. GI Compliance is being developed to simplify the management of the bylaw compliance. Barry Orr, a Bylaw Enforcement Officer, City of London, trialed the software. Barry’s use of GI Compliance has streamlined data entry and location management, making compliance status and inspection information readily available. Barry estimates that the City of London has saved nearly $100,000 in sewer maintenance costs since adopting the GI Compliance program.

The City of London is considering running a fully integrated GI Compliance pilot program. That pilot would allow commercial kitchens to upload their interceptor service details to the city. With 2,200 food service establishments and only one GI bylaw compliance officer, the GI Compliance Live Monitoring program could prove to be what the City of London needs to keep FOG out of their sewers.
