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/completed. Please submit 3 sets of revised drawings to a Development
Services Permit Coordinator, if required, or a written response to the review comments to the Development Services Permit Coordinator and the Pretreatment Reviewer.
Please complete and return the earlier provided GGI sizing worksheet. You will not need to complete the HGI section of that worksheet.
Locate the outside grease interceptor as close as possible to the kitchen fixtures to reduce to reduce maintenance (grease build-up) on the discharge line from the kitchen to the GGI.
Provide a detailed cut sheet showing the proposed GGI for this location.
Please provide the anchoring system design that will prevent GGI lifting.
The 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 prior to the setting of the GGI. I prefer to be present during the setting of the vessel to eliminate potential problems. The mechanism that
fastens the GGI to the concrete anchor will need to be inspected as well.
A water test will need to be conducted, before any 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.
