If you do not know the ratio of female to male amenity users use a 50 per cent breakdown for each Refer to the WEMP samples for an example of this 5 Column G indicates the number of times the fixtures are used per day For example you may assume that people wash their hands every time after using the toilet So if they use the toilet four times per day four hand washes per day would be used 6 Column H indicates the number of days the premises are operational Link Column H to cell C10 in Tab G6 where you have already specified operation days 7 Column I indicates the flow rate of the fixture in litres per minute You may source this information from the fixture s specification or WELS rating If you do not have the specification or WELS star rating for the fixture you may need to measure the flow rate You will need a container where you know the volume for example an empty 600ml bottle or a 9L bucket and a stopwatch Record how long it takes to fill up the container at what you consider to be a usual flow rate for that fixture Divide the volume in litres by the time in minutes For premises with too many fixtures you may choose to take a representative sample of them but remember that if they are inefficient you may need to upgrade them all so it may be cost effective to measure all fittings Example 1 It took 30 seconds to fill up a 9L bucket from a shower Shower flow rate 9L 0 5min 18L min Example 2
