Pit assembly with removable cartridge

A removable cartridge configured for installation in a pit comprising a pit inlet connector and a pit outlet connector comprising:

• a chassis;
• a cartridge inlet connector configured to operatively couple in fluid communication to the pit inlet connector;
• a cartridge outlet connector configured to operatively couple in fluid communication to the pit outlet connector;
• an inlet locking mechanism mounted to the cartridge inlet connector and selectively movable about and between a locked position and an unlocked position, the locked position configured to securely couple the cartridge inlet connector to the pit inlet connector, the unlocked position configured to release the cartridge inlet connector from the pit inlet connector;
• an outlet locking mechanism mounted to the cartridge outlet connector and selectively movable about and between a locked position and an unlocked position, the locked position configured to securely couple the cartridge outlet connector to the pit outlet connector, the unlocked position configured to release the cartridge outlet connector from the pit outlet connector;
• and
• a piping system in fluid communication with the cartridge inlet connector and the cartridge outlet connector and mounted to the chassis.

A method for connecting a piping system in fluid communication to a piping infrastructure, the method comprising:

• inserting a removable cartridge into a pit liner, the pit liner comprising a pit connector positioned in a pit interior defined by an inner surface of the pit liner, the pit connector being in fluid communication with the piping infrastructure, the removable cartridge comprising the piping system, a chassis, and a cartridge connector in fluid communication with the piping system, the piping system and the cartridge connector mounted on the chassis;
• operably coupling the cartridge connector to the pit connector to place the piping system into fluid communication with the piping infrastructure;
• and
• engaging a locking mechanism to secure the pit connector to the cartridge connector.

A pit assembly comprising:

• a pit liner defining an inner surface and an outer surface, the inner surface defining an interior of the pit liner, the inner surface and the outer surface further defining a pit opening proximate to an upper portion of the pit liner;
• a pit piping element positioned in the interior of the pit liner;
• a removable cartridge positionable within the interior of the pit liner, the removable cartridge comprising:
• a chassis, and
• a piping system in fluid communication mounted to the chassis, the piping system comprising an inlet;
• and
• a means for operably coupling and locking the pit piping element to the inlet of the piping system of the removable cartridge in fluid communication.
