Modelling intermittent water supply systems is a challenging task because these systems are not fully
pressurized pipeline networks but networks with very low pressures, with restricted water supply hours per day.. The
alternate emptying and refilling of water pipelines makes it problematic to apply standard EPANET based hydraulic
models because of low pressures and pipes without water. EPANET source code was adjusted to allow for modelling
pressure dependent demands, for adjust flows in pipe, for head loss and for velocity. Cases study of Gandhinagar
water supply project NC-14 was discussed, to illustrate the practical use of this approach. The experience from using
and adjusting the EPANET engine for the modelling of intermittent water supply systems is discussed in this paper.]
