Water supply distribution systems are facing several challenges to deliver acceptable quality and adequate quantity of water with the required velocity and pressure. These challenges come from rapid population growth, urbanization, migration to urban areas and cities, scarce water resource, poor design, poor operation and poor maintenance of the system. These also expose infrastructural decay; inefficient distribution system and water demands on pipeline increasing every day. Togoch’ale Town, in Somali Regional State is rapidly grown commercial town with many refugee camps. To stimulate the growing economic development and to assure the residents’ health, reliable and adequate quantity of potable water supply is needed. Therefore, evaluating the hydraulic performance of water supply distribution system of the town was have paramount importance to upgrade the distribution system or add new resource to meet current and future demand. Evaluating hydraulic performance of water distribution system is useful to identify the gap between supply and demand, as well as the deficiency of hydraulic parameters in water supply distribution system. Hence, the main objective of this research is to evaluate hydraulic performance of water distribution system based on widely accepted key standard. Primary and secondary data was collected. Hydraulic network Simulation with WaterGEMS was be carried out to track water supply, water demand, flow velocity and pressure at each node. Both single and extended period simulation was be carried out. The result of the hydraulic analysis of the distribution pipeline for the peak hour demand of the base year 2023, Shows that 30% of the nodes in the distribution pipe line has a pressure in the range of 15 to 70 m and meet the minimum and maximum pressure requirement of the urban water supply design guideline by MoWE (2006).
