To reduce the consumption of potable water in new buildings through the effective management and monitoring of water consumption.

• Increase awareness of water usage within the building.
• Identify and monitor large water uses and changed consumption levels to improve management and maintenance as well as to encourage reductions in unnecessary consumption.
• Reduce costs related to water consumption.
• Manage water demand for different building areas and uses.
• Reduce the need for large-scale increases in water infrastructure in the future which are likely to increase costs over time as well as impact on our rural and urban landscapes and communities.

Due to increasing population densities and relatively high levels of water consumption, much of the UK is at risk of water shortages which are likely to increase over time as rainfall patterns due to climate change . Reducing water consumption in the UK is, therefore, crucial.

Sub-metering water consumption means that water consumption can be better accounted for. Large water consumers can be identified with the aim of encouraging the reduction in water use where practical. Moreover, changes in consumption can be identified and dealt with as appropriate, thereby minimising risks of systems failures which can have costly and disruptive consequences.
