water subsystem in conception of the IUWS, several subsystems are built up, i.e. water
usage, water sources, desired water system, used water system, and
rainwater system, which are finally constructed together as one IUWS.
water usage contains the water information of water end-users, including water demands
associated with required water qualities, and used water amounts with their
water qualities.

water end-user can have different water usages profiles, which results in
different kinds of water usage, and they are named as the water usage
scenarios.
in general, it is the certain functional unit in cities and consequently, its
water system can be managed and coordinated within one entity.
It has the same structure as WUU but on a small scale that mostly focuses
on the single big buildings or mono water end-users.
