| Abstract | The major problem in the planning and operation of water distribution systems is ensuring an adequate level of service at all points in the system under various loading conditions. This work deals with assessing the water distribution system of the First Philippine Industrial Park in terms of sufficiency in flows and pressures and adequacy of storage volumes. A computer model to represent the distribution network and the facilities had been prepared using WaterCAD. After model calibration (by adjusting K-values and Cvalues) and validation, flows identifying with existing demand, future demand and emergency demand had been simulated over an extended period of 24 hours. It is an integral part of the simulation to have demand data on a demand pattern format. These were obtained from field surveys of consumptions of the existing water users and were estimated for the future condition. The simulation results for pressure were drawn as pressure contours. Booster pump operations were compared._ It has been found that the system can provide satisfactory levels of flows and pressures even into the future. This deteriorates under emergency conditions such as fire and pump failures. It has also been found that the storage volumes are under managed as pressure is maintained in the system through pumping. WaterCAD has been observed to fail in recognizing hierarchy in controls. This was rectified using simple programming commands for inclusion in the control preview. An operations strategy was developed by modifying the operational settings of the booster pumps. This will result to significant energy savings. An operations strategy of a wider scope including an economic analysis was also recommended. ii |
