added sediment loading to the interceptor or increasing the interceptor size.

3. If the disposer is kept in the plans, more frequent pump outs may be required to keep the fat,
oils, greases and sediment levels captured in the GI within the city's acceptable limits.
This will bac' coorditi ted between the city and the client at- time of operations. They

13. Please have the GI installer notify me prior to the setting of the GI. I prefer to be present during
the setting of the vessel to eliminate potential problems. Additionally, 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 one compartment at a time; no leaks should be visible through the baffle wall or outside
the GI.
W/e will heave the contractor contoc tt ytpufor instcallotion sequencing and to c oorclinote
schedules.
14. An exterior hose bib should be installed as near as possible to the GI location to facilitate the
pumping, cleaning, and priming of the GI.
