Reviewer: Rick Bagan Division: Wastewater Treatment Plant / Pretreatment
The subject application has been reviewed but cannot be completed until the following
items have been addressed.
1. I do not see a grease trap included with the submitted plumbing plans. Is it the intent to
remove the old existing interior grease trap and replace it with a new exterior Gravity
Grease Interceptor (GGI)? If so, please provide detailed cut sheets showing the proposed
GGI for this location.
2. 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
• Rating specific for traffic
• Graded away from the manholes to prevent runoff from entering the GGI
• 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
4. The following fixtures must not be connected to the GGI (unless approved by
pretreatment):
• Hand sink
• Vegetable prep sink
5. 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.
6. 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.
