Abstract
A tank sump has a one-piece body comprising a hollow base member for collecting fluids leaking from a piping system, the base member having an upper portion and a lower portion, and a hollow riser section having an upper portion and a lower portion, the riser lower portion extending upwardly from the base member upper portion, the riser section having sidewalls with alternately adjacent vertically extending wall portions and outwardly extending, U-shaped grip portions. An integrally formed cover is defined on top of the riser section upper portion. The cover may be cut off from the riser section of the body. A gasket may extend between the cover outer periphery and the outwardly extending grip portion of the riser section, and a mechanism removably secures the cover to the outwardly extending grip portion with the gasket therebetween, in a substantially water resistant sealing manner. The cover may alternately be cut away from the body and discarded. A substantially rigid lid is removably mounted on an outwardly extending grip portion of the riser section, and a mechanism mounts the lid to the outwardly extending grip portion in a substantially watertight manner.
