A UK based NHS board had observed the potential for problems when moving operations from one of their older buildings to another area of the building. The abandoned area of the building would be left with a huge water supply system with nobody using it, increasing the potential of bacteria growth. The problem was, shutting off the water supply was not an option as it still supplied the occupied areas of the building. The NHS board called upon the knowledge and expertise of Biochemica Water to reduce the risk of legionella.

The NHS board called upon the knowledge and expertise of Biochemica Water to reduce the risk of legionella.

WHAT WE DID

• Installed two automatic flushing valves, reducing the need for staff to physically flush the system.
• Linked the automatic flush to the temperature of the water, meaning when the water reached a temperature at risk of legionella growth the system flushed. This is an alternative to a timed automatic flush which would not be as accurate and could waste water.

WHAT WE ACHIEVED

• Significantly reduced the potential for bacteria proliferation.
• Saved time and money by installing automatic valve rather than the alternative of physically flushing the system.
