detail sheet.
We often get asked how much grease our grease traps and interceptors hold. We will look at our 1,500 gallon HS20 traffic rated grease trap and answer that question for this tank. The amount of grease held by a precast concrete tank is surprising!

Compartment A (first compartment) holds 5,461 pounds of grease

Compartment B (second compartment) holds 2,659 pounds of grease

Total capacity is 8,120 pounds of grease


Notes
• In an ideal world, grease should only fill compartment A.
• Compartment B acts as an emergency overflow or secondary protection for the utility.
• The key to grease retention is extending the baffle ninety and outlet tee twelve inches off the inside floor.
