  • Sewage tanks and grinder pump systems
    Patent number: 7624892
    Abstract: A sewage tank for use with a pump such as a grinder pump to convey sewage. The sewage tank includes a container having an upper portion and a lower tapering portion defining a chamber for containing the pump. The lower tapering portion has a reduced size compared to the upper portion. The upper portion and the lower portion may include a plurality of intersecting vertical ribs and horizontal ribs defining a plurality of recessed pockets. The lower portion of the sewage tank may also include an outwardly-extending flange sufficiently sized so that soil may be backfilled around the bottom of the tank to prevent the tank from floating upward out of the ground due to its buoyancy under high ground water conditions. A sewage tank having a stepped flange is also disclosed.
