Looking at the Water Use Reduction - Additional Guidance in the section for Dual flush, they say: " For the female water closet usage, there is a 1:2 ratio in terms of number of full-flush to low-flush uses per day. For the male water closet usage, there is a full-flush usage per day." Does this mean that if a visitor female with 0.5 uses/day and male visitor with 0.1 uses/day according to the default fixture uses, then in the average for dual flush the default uses are broken down by the ratio like this?
(0.033 uses/day x full flush rate) + (0.066 uses/day x full flush rate) +
(0.166 uses/day x full flush rate) + (0.332 uses/day x full flush rate)
divided by 0.6 total female & male uses.
Is this assumption correct?
