Abstract
A grease trap for separating grease and solid waste from waste water. The grease trap includes a tank having a downwardly shaped bottom. An upwardly shaped divider divides the tank into an upper chamber and a lower chamber. A hole near an upper part of the divider allows waste into the upper chamber. An inlet invert in the tank receives incoming waste water, while an outlet invert removes water from the tank. A lid covers the tank. A pipe extends through the lid, upper chamber, and lower chamber for sucking solid waste out of the lower chamber.
