Water efficiency

Low water use taps (aerated, push top, PIR), low flush toilets and low flow showers can all reduce the day to day potable water consumption within a building, at no or very little extra capital cost for a new building

Metering and leak detection can assist in the management of water consumption within a building. Understanding what is being used and how this can be reduced can lead to an action plan, setting targets and monitoring progress for reducing water consumption within the building.

External and internal planting tend to rely on irrigation systems. To minimise water consumption these systems can be installed to only release water when the soil reaches a certain level of ‘dryness' or to use collected rainwater. Alternatively the planting can consist of plants that solely rely on precipitation.

Water recycling can be used to reduce the potable water consumption within a building and should only be considered once the more cost effective water efficiency measures have been specified. Water recycling can consist either of rainwater collection or greywater recycling. These systems can be used to flush toilets and irrigate planted areas and should be sized according to the amount of recycled water that will be used e.g. flushing capacity and can be collected (in the case of rainwater). There should always be a potable back up to this type of system.
