To reduce the consumption of potable water in new buildings through minimising wastage due to water leaks.

• Reduce potable water wastage associated with leaks.
• Minimise damage, costs and disruption arising from water leaks.
• Reduce costs related to water consumption.

Water leakage within customers’ properties represents 6% of the total public water supply in England and Wales1Department for Environment, Food and Rural Affairs.

Available from www.gov.uk/government/uploads/system/uploads/attachment_data/file/69346/pb13562-future-water-080204.pdf . This is equivalent to 25% of the total water leakage, with the rest being attributed to water distribution systems of the supply companies. Water leaks in building systems are responsible for major damage to property resulting in major disruption and costs. It is, therefore, important to ensure that water leaks are detected and controlled on a building level as early as possible.
