The riser kit comprises at least one collar extension having, a lower edge for engaging an upper edge of the upwardly extending walls of the grease interceptor, a middle portion forming an upward wall extension for the grease interceptor, and, a top edge sized and shaped to engage the cover to permit the cover to be secured to the extended grease interceptor. The riser kit also has a means to secure the collar extension to the grease interceptor. Also disclosed is a latch assembly for securing a cover onto a container, the latch assembly comprising a catch member secured to the container transverse to a container wall at an upper end thereof, a latch member pivotally mounted to the cover adjacent an edge thereof and positioned to register with the catch member. The latch member has a hook portion and a lever portion wherein pivoting the lever portion when the cover is positioned on the container causes the hook portion to engage and disengage with the catch member. A method of installing a wastewater grease interceptor is also disclosed.
