Within the framework of immense plans for water networks renewal in Egypt as a potential solution for Optimized Renewal Plans, this research investigates water network asset management numerically. Basically, previous research in asset management domain were amassed. Within the umbrella of Holding Company for Water and Wastewater "HCWW", 3 areas in 3 governorates were investigated namely; (Damietta [area 1], Gharbia [area 2] and Matrouh [area 3]). "Water GEMS" model was selected, as it offers a renewal plan, which depends on Risk-Score of pipes. "GEMS" was operated where three simulations were achieved to the 3 areas, and pipe break analysis was utilized to incorporate several aspects (i.e., Pipe age, diameter, material, feeding critical customer and criticality). The results indicated that this method could support accurate pipe renewal plans within financial conditions. Results emphasized that the obtained plan can 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.
