While there is no question about the fact that demands in a water distribution system can be dependent on pressure, the importance of considering pressure based demands in modeling has been widely discussed. This discussion often centres on whether demands are pressure or volume based. This, however, is the wrong question. Demands are BOTH pressure and volume based and demands are really a sum of several difference components of demand including volume based demand, controlled pressure based demand, uncontrolled pressure based demand and leakage. Each of these components is described in the paper with some special consideration of the case where pressure approaches zero and the implications of considering these components.
