Grease Traps / Sand-Oil Separators / Water Separators

Mitchell Concrete is Alabama’s largest manufacturer of commercial grease traps and separators. Our grease traps are designed for maximum efficiency, structural durability, and compliance with the following standards: ASTM C890, ACI 318, ANSI Z1000 and ASME A112.14.6. Materials and manufacturing conform to ASTM C1227/C1613.

Our Mitchell “no-lid” clamshell style tanks are significantly stronger, by design, than conventional “bucket style” flat top tanks. The Mitchell H20 commercial interceptor is built using a 5000 PSI.+, fiber reinforced concrete mix poured over a structural #4, #5, and #6 steel reinforcing cage. Like a parking deck, this steel cage is constructed bidirectionally and wraps vertically around the tank edges- tying the horizontal steel of the tank top and bottom with the vertical steel in the tank walls. In addition, the top access openings are reinforced with steel tied into the top of the cage. This tank series is available in 4” and 6” inlet/outlet sizes and features poured-in-place rubber seals for inlets and outlets. The baffle wall is constructed with a poured-in-place PVC sleeve, allowing for a solid crossover pipe installation by providing a “hard point” for which to glue the baffle wall plumbing. This tank series also comes standard with two 24” top access openings that mate to our line of concrete grade rings and approved metal ring/cover sets adding to the ease of installation associated with the Mitchell Concrete product line.
