Waste Water Networks (WWNs) Modeling and Optimization. Application to a Study in Northern Coast of Spain

The change of the hydrologic cycle is one of the biggest concerns related to global warming effects. Larger intensities of rainfall events greater in magnitude are foreseen in the coming years, strongly affecting Waste Water Networks (WWNs), leading to higher flowing rates and reaching the limit of the hydrologic cycle’s capacity or even exceeding it. In this field, the proper modeling of a WWN is a useful and economical approach to detect the networks’ critical issues. This work presents a procedure to model a WWN, including different infrastructures and controls and testing different conditions using the EPA-SWMM 5.1 hydraulic solver. The proposed method was applied to a simplified WWN located in Asturias Region (Spain)
