Within the framework of immense plans for water networks renewal in Egypt, as a potential solution for Optimized Renewal Plans, this research was originated with the intention of investigating water network asset management, numerically. Basically, previous researches in asset management domain were amassed. Within the umbrella of Holding Company for Water and Wastewater "HCWW", 3 areas in 3 governorates were investigated (i.e. Damietta [area 1], Gharbia [area 2] and Matrouh [area 3]). "GEMS" model was selected, as it offers a renewal plan, which depends on Risk-Score of pipes. "GEMS" was operated. Three simulations were achieved to the 3 areas, where pipe break analysis was utilized to incorporate several aspects (i.e. Pipe age, diameter, material, feeding critical customer and criticality). Results were obtained; analyzed and presented. The results indicated that this method could support accurate pipe renewal plans within financial condition. Results emphasized that the obtained plan will assist decision makers to allocate pipes to be replaced, based on their risk. It was recommended to utilize this methodology to achieve high performance. It was suggested that networks replacement should be based on priorities.
