Fluid evacuation collection vessel assemblies and fluid evacuation systems and methods

A collection vessel for receiving a fluid as part of a fluid evacuation system, the collection vessel comprising:

• a top end of the collection vessel;
• a bottom end of the collection vessel;
• one or more sidewalls extending between the top end and the bottom end to thereby define an internal volume for containing the fluid;
• a support member disposed within the internal volume of the collection vessel, wherein the support member is connected to and extends between the top end and the bottom end of the collection vessel, and extends through the bottom end, wherein a drain is formed within the support member and the drain is in fluid communication with the internal volume and a drain valve;
• and
• one or more reinforcement members mounted to the support member, wherein the one or more reinforcement members extends outwardly from the support member and is proximate to an inner surface of the one or more sidewalls to prevent deformation of the one or more sidewalls to thereby maintain the internal volume of the collection vessel when the internal volume is subjected to vacuum pressure.

A system for evacuating fluid from a reservoir, the system comprising:

• a vacuum source;
• and
• one or more fluid extraction apparatuses, each comprising:
• an extraction device;
• and
• a collection vessel comprising:
• an internal volume for containing the fluid,
• a support member disposed within the internal volume of the collection vessel,
• one or more reinforcement members mounted to the support member, wherein the one or more reinforcement members maintain the internal volume of the collection vessel,
• an extraction valve in fluid communication with the internal volume and with the extraction device,
• a vacuum source valve wherein the vacuum source valve is in fluid communication with the internal volume and the vacuum source, and
• a drain valve in fluid communication with the internal volume and a storage tank;
• a pedestal including a drain pipe in fluid communication with the drain valve and the storage tank, and wherein the one or more fluid extraction apparatus is mounted to the pedestal via the drain valve;
• and
• wherein during a fluid evacuation process the internal volume is subjected to vacuum pressure generated by the vacuum source.
