Abstract

This specification covers design requirements, manufacturing practices, and performance requirements for monolithic or sectional precast concrete grease interceptor tanks. This standard describes precast concrete tanks installed to separate fats, oils, grease, soap scum, and other typical kitchen wastes associated with the food service industry. The different materials and manufacturing practices of precast concrete grease interceptor tanks are presented in details. Structural design of grease interceptor tanks shall be by calculation or by performance. The different structural design requirement of grease interceptor tanks includes; concrete strength, reinforcing steel placement, and openings. The different physical design requirements of grease interceptor tanks includes; capacity, shape, compartments, inlet and outlet pipes, baffles and outlet devices, and top slab openings. Testing for watertightness shall be performed using either vacuum testing or hydrostatic testing.
