Where a timer is used to physically limit the use of showers or taps within a set period of time, this can be used as the basis for calculating a reduced flow rate.

For example, where use is limited to 2 minutes, 4 times per hour, for a shower or tap with a flow rate of 8 l/minute, the flow rate can be calculated as follows:

8l/minute x 8 minutes/hour = 64 l/hour = 1.07 l/minute
