Benefits

Safety and Security Benefits:

• Prevention of communication and the passing of contraband between cells.
• The ability to turn off the plumbing in individual cells or groups of cells to prevent the flushing of contraband.
• A vacuum flush toilet eliminates the "flush plume" thus reducing the spread of germs.

Water Usage and Cost Benefits:

• ½ gallon of water used per flush.
• Vacuum plumbing systems can reduce water usage by up to 68%

Maintenance Benefits:

• Drastically reduces system blockages
• When blockages do occur, they can be located at the fixture, making it easier to identify inmates attempting to vandalize the plumbing system.

Flexibility Benefits:

• Flexibility in layout and design—vacuum plumbing systems do not require continuous slope and can be routed overhead around existing systems.
