therefore confronted with the options of a change in either inlet concentration or
flow rate.
It is important to stress at this point that water pinch provides a systematic
approach for modelling an existing water network, rather than a single solution
to a problem. The available software provides a useful tool for the engineer in the
decision-making process, but identifying the actual minimum flow rate is an
