ABSTRACT:
A sump shield assembly particularly adapted for creating a watertight seal with a container sump which are used with underground fluid storage tanks is disclosed. The assembly prevents water from entering a containment sump. This assembly includes a sump adapter, a sump shield and spill collector boots which couple to spill collectors that are commonly used to collect fluid spilled during the filling or evacuation of underground fluid storage tanks. The sump adapter is mounted to a containment sump, and includes a groove to receive a sealing member. The sump shield is shaped and configured to mate with the sump adapter and the gasket, and is secured to the sump adapter with releasable latches. The latches are used to make the shield easily removable, and also provide the clamping force needed to compress the gasket sufficiently to create a watertight seal. The spill collector boots join the spill collectors and the sump shield, and have watertight seals at both ends. Alternatively, a watertight sump lid is placed over the sump shield adapter and is secured to the sump adapter with releasable latches, thereby providing a watertight containment assembly. The watertight sump lid is used when no upward protrusions are required.
