Figure 13: Composition of grouped end-user’s water usage profile (EUWUP)
Each water end-user can have several EUWUPs simultaneously, which represent
different water utilisation patterns. Water consumption depends on many factors, such as
local traditions, water fixtures and economic levels. Through the demand side management,
water end-users can have different water usage profiles. The demand side management is
not directly included as it is not the focus of this research. Instead, its effects can be reflected
by different EUWUPs, which are named as the water usage scenarios in IUWS.
General EUWUP. If the detailed EUWUP is not available, the general EUWUP can be
used for roughly estimating water usage. General EUWUP is assessed by equivalent
average water consumption. Two possible units of EUWUP are adapted. One is the capita
