ABSTRACT:
A sump liner comprising a liner wall joined with a base member, the liner wall extending about the periphery of the base member, the liner wall comprising a primary reservoir portion and a secondary reservoir portion, with a weir extending from the base member and the inside surface of the liner wall. The weir divides the sump liner interior into a primary reservoir and a secondary reservoir, with a primary pump to remove water from the primary reservoir and a secondary pump to remove water from the secondary reservoir. The primary reservoir receives drainage water through an inlet pipe. The secondary reservoir receives drainage water that flows over the weir in the event the primary pump in the primary reservoir fails, in which case the secondary pump in the secondary reservoir pumps out the water.
