Metering recycled water

Water-consuming plant or building areas consuming 10% or more of the building’s total water demand need to be sub-metered. This applies to recycled water, such as rainwater, grey water or process waterΒ as well as mains water.

The aim of the Issue is to encourage reductions in water consumption, which is beneficial, regardless of its source. Monitoring the use of recycled water, may also help to reinforce the benefits of doing so and encourage further reductions.
