Reviewer: Les Krestel Division: Wastewater Treatment Plant / Pretreatment
The subject application has been reviewed but cannot be completed until the following items have been addressed.
The installation of a GGI will be required for this building in phase 2 to capture fats, oils, and grease (FOG) that will be created from food service establishments (FSE) that will
occupy spaces in this building.
GGI’s should be placed as close to possible to the kitchens they serve.
Size GGI’s to accommodate the maximum number of possible FSE that may occupy spaces in the building. The minimum size GGI for a FSE is 500 gallons.
Provide detailed cut sheets showing the proposed GGI/GGI’s for this location.
A GGI should have:
6” PVC lines entering and exiting the GGI
Proper venting allowing free air exchange between both chambers
Brackets supporting all downlegs in GI. It is very important to secure the downlegs to the vault walls; it may prevent costly repairs in the future. It is recommended to use stainless
steel unistrut bar and 6” clamps to secure pipe
Specific for traffic
Graded away from the manholes to prevent runoff from entering the GI
Man hole covers above each downleg for inspection and maintenance
The following fixtures must be connected to the GGI:
Mop sink
3 comp sink
Dishwasher and prewash
Prep sink, if used for meat
Floor drains in the scullery/food prep area
The following fixtures must not be connected to the GGI (unless approved by pretreatment):
Hand sink
Vegetable prep sink
Please have the GGI installer notify me for inspection soon after the GGI has been installed but before complete backfill. The grease drain will need to be inspected running to the GGI.
A water test will need to be conducted, before complete backfill, to verify the integrity of the tank. The tank is filled with fresh water, no leaks should be visible through the baffle
wall or outside the GGI.
Please call me Monday-Friday for questions and assistance.
