These negative pressures indicate that there is inadequate head within the distribution network for water conveyance to all the sections. About 19 percent (18.52%) of the total number of nodes analyzed had negative pressures while 69 percent (69%) of the nodes had pressures less than the adopted pressure for the analysis. There was no statistical difference between the results of Epanet and WaterCAD, however, Epanet produced slightly higher results of pressure and velocity in about 60% of all cases examined. This study evaluated the performance of Wadata sub-zone water distribution system with respect to pressure, velocity, hydraulic head loss and nodal demands using WaterCAD and Epanet.
The result is that overall water demand is usually not satisfied. Population explosion in urban settings usually exerts enormous pressure on existing water supply systems.
