Design and Analysis of a Sustainable Water Distribution Network for the Aeta Community in Brgy. Diaz, Porac, Pampanga

This experimental research aimed to propose a conceptual design of sustainable water distribution networkthat addresses the current water system in the Brgy. Diaz, Porac, Pampanga. In the barangay, the mainsource of water is groundwater that came from manually operated pump that is located at the highestelevation of the barangay. Water samples were collected for physiochemical and microbiological testing ina laboratory. The water sample only failed the DOH standards for heterotrophic plate count, having aresult of 2000 MPN. The software used to design the WDN was EPANET. Beforehand, collected datasuch as the difference in elevation, length, and the water demand for each station. The elevations andlengths were measured in actual by means of auto-level surveying. This study based the design of WDNwith the future water demand, since the design that can accommodate the future demand, will and can alsosupply the current water demand. The total water demand in the barangay was distributed equally to thesix stations. The design consists of pipes having a diameter of 100mm and 200 mm, one main storage tank,and a pump with 1.5 hp. The pressure and head loss were analyzed during normal hours and peak hours.The maximum and minimum pressure within the network were 22.63 m and 11.88 m, which are within 10psi to 60 psi. Based on the output of EPANET, the design of WDN can fulfill the current and future waterdemand based on its water flow rate.
